Looking to make your SuperSport 939 / SuperSport S 939 breathe better? The Sprint Filter P08 filters for the SuperSport are by far the best performance air filters you can install.

What makes them so great?

Sprint Filter with P08 has reinvented the concept of a special air filter. Unlike materials like cotton which fiber breaks easily or sponge that is inconsistent under pressure but an innovative polyester material that allows an air passage to be constant and calibrated.

P08 is an air filter totally different from others. There isn't a filter in the world built with such technology. The membrane filter consists of a fabric of polyester threads from ø 5 microns. What's more, the filtering surface is doubled than any other special filter. Here's an microscopic shot of the cotton filter and our P08 polyester in comparison.

What does this all mean?

Simply put, the Sprint Filter P08 air filter is able to filter out more dust than the OEM air filter while being able to flow more air.

What about maintenance?

The Sprint Filter P08 material is a non oiled material. Unlike other filters where oil has to be applied to catch dust and dirt, since Sprint Filter's P08 material is able to do so without oils, to clean your filter you simply need to clean it with compressed air and that is it. This means that you will never have to by another air filter again.

If you want to nerd out and read a 3rd party testing done by University of Wales of all performance air filters, here is an in depth analysis of filter flow tests: https://issuu.com/sprintfilter/docs/air-filter-element-flow-analysis_wa_b9b4f7976f1b38

Sprint Filter is also the OEM supplier of the air filters found in the Panigale R and Superleggera models.

Where can I get one?

It's a fact that OEM air filters have considerable air flow capacity redundancy to take account of filter use and normal flow reduction. Unless you increase the airflow requirements of the engine sports air filters are a waste of money. Even without a cleaner on it the airflow on the Supersport will not exceed the ability of the std air filter element even as it nears its end of life.

I was involved in the technical aspects of things like air cleaners. An OEM will have a ream of specifications that must be met. Whatever the after market filter makers say they struggle to meet these specifications. For instance the surface area of the Ducati filter medium in the pictures above is considerably larger than the after market one. These specs ensure clean air for longer periods of time these are not race engines that get stripped and rebuilt before they get worn out.
So your bike will not breathe better, do you really believe that a manufacturer would put on a filter that restricted air flow and consequently performance?

So spend your money wisely. But hey it's your bike.

Would a full exhaust and the adjustments required to accommodate it fit under increasing airflow requirements in a fuel injected bike? I know I've had to use free flowing air filters on carbureted set ups after a full exhaust and re-jet, but I've always been kind of curious about it in EFI set ups.

To honest just an exhaust and rejet would not surpass the airflow of the standard filter. It's a nice thing (for some) to do and the increase in intake noise is always a bonus and like a louder exhaust provides the feeling that the vehicle whether car or bike is faster.

A standard air cleaner is designed to achieve more air flow than needed right up to the end of it's service interval. Turbo cars are another subject as air volumes can be dramatically increased relatively easy. But even then it's not considered necessary until exhaust and turbo are changed.

In many cases as found by the UK's MCN in recent dyno tests they removed the exhaust valve and added a sports silencer to a bike only to show a drop in bhp over a standard set up, that is until a power commander was fitted.

But if an owner wishes to fit a sports air filter it's their choice. Me? knowing what I know would never fit one.

I have had great improvements on some of my other bikes by changing the filter. On the Indian Scout taking the filter and airbox out it made a huge difference. However, on the SS even with the full Akra system there is no major improvement in performance. So, concur with Steve on this one.

Unless you can prove its an improvement then there isn't one. Do you really believe that a major manufacturer who strives for performance would fit an air cleaner that cause the engine breathing problems. It just sounds faster. Yoou need to do significant tuning to a vehicle to need a more free flowing cleaner.

There are many factors you are not thinking about. Like emission standards and more. Also, major manufacturer rides a thin line between profit and loss, so every penny/dollar counts. If there was no improvement with a filter, they wouldn't supply the same filter material as this filter for the Panigale R and Panigale Superleggera. Ducati's own race teams would have just used paper filters and etc...

Also with this thinking, you should never ever replace your air filter, even if it is dirty, because with your mentality air filter/flow has nothing to do with the power of your bike.

Read the complete study done by the University of Whales link posted on the original thread, and there is your proof that filters do make a difference. Mind you there has been many dyno tests done. Not talking about old carburated bikes with no advanced ECU's as the current bikes. The current bikes will adjust/adapt to changes which in a simple case like an air filter change will result in higher power output since the ECU will be able to adjust to the parameters of the air flow and provide sufficient fueling.

Ducati puts this filter in when you get the full akra exhaust and up-map. But you are right, without changing the fuel table, increased air wont really do anything for you. However, if it filters better than OEM, that is a good thing.

I have not seen the intakes on the SS. Many bikes its not the air filter that is restricting the flow - it is the air box the filter is sitting in that is doing the restricting. So in many cases nothing changes when you replace the filter.

These bikes are not built on 1950's technology. The ECU is able to adjust/adapt to changes that would happen from running a free flowing air filters and more (things like ambient air temperature, fuel quality, elevation etc...). So yes, without changing fuel tables by flashing your bike, you will gain more power and your bike will also run more efficiently.

I might be missing something, so why would you need a power commander,rapidbike evo, ducati upmap if the ecu handled everything itself to get more power? I was under the impression that it would just change things enough to get the same results it was programmed for. So yes, it can handle the extra air, but it really doesnt do anything better with it. I think they call it the fuel trim settings.

You would need those in cases where the modifications exceeds what the ECU is able to adjust for.

So lets say the ECU can adjust between -5 to +5 range, maybe a Rapidbike Evo can do this at -10 to +10 range and the Rapidbike Race can do this at -20 +20. (I say maybe, because the numbers I am using are not accurate, but just to let you know what the differences are. The parameters in which they can adjust are higher with each case)

For a bike which is stock and you've change the air filter, the factory's ECU can adapt to this change. But if you were to run a full exhaust, you'd definitely need to run an aftermarket fueling system or some type of a upmap.

You haven't backed your claims up with a single fact. I've read the study. All its says is that filters constructed of various materials will have different maximum flow rates. Duhhhh! As if an engineering study was necessary to highlight this obvious fact. No filter at all will clearly have the highest maximum flow rate, so is that the preferred option???

The study makes no mention of the effectiveness of various filter types. That's why a filter is on an engine, to filter out damaging dirt. So any study that doesn't consider this key criteria in comparing filter construction materials is basically useless for a road engine.

And I encourage everyone to read the very last paragraph of the study. It clearly states additional research is necessary to determine what effect on engine performance different maximum flow rate filters has. And that additional, yet to be conducted research, will only be applicable to the EXACT configuration engine upon which any future research is conducted.

P.S. and in no way is the study independent. The way it refers to the 'patented technology' of the P08 filter you'd think it was written by the filter manufacturer's marketing department. I'd be willing to bet they funded the study.

I would also suggest people read up on 'Resonate air boxes'. They are deliberately engineered as a complete finely tuned unit to increase power at some predetermined rev range by 'supercharging' the intake (a bit technical in this short post to explain how). For a road bike you would expect the manufacturer to place that performance boost in the mid range (usually where valve overlap creates a potential problem). Go fiddling with any aspect of it and you can upset this highly engineered unit.

Peak HP isn't all that critical for a road bike, it is for a pure track bike running at WOT and redline constantly. Think about it, an air filter that materially chocked the engine say below 3/4 max revs would completely kill the engine at WOT. The main thing an air filter needs to do is effectively filter the air on a road bike. That's the number one, two and three most important criteria. The 'possibility' of a tiny HP increase at WOT as a trade of for reduced engine life is a poor investment, IMO.

So you must have read that the Sprint Filter is able to filter out smaller particles than the paper filters found on OEM filters right? Have we also mentioned these filters are non-oiled, and are cleaned simply with blowing compressed air?

So as far as a road user is concerned, it filters finer particles than the OEM filter, you will not need to purchase another filter again, simply blow it out with compressed air and reuse for the life of your bike, which means you will save money.

I am not going to keep arguing over this, as it is just becoming a noise in this thread, for some of us, it is the first thing we change on our bikes.

Again, you've prevented not a single piece of independent evidence of either the effectiveness or performance benefit of these filters. I'm assuming you have some direct or indirect commercial interest in them, and this thread has been nothing more than an advertisement for the product. Most forums I follow don't permit commercial advertising such as this.

The sprint filter is in the ducati performance akra race exhaust system kit, its a performance filter endorsed by ducati for their bikes. That alone indicates its a good filter. The materials in the sprint filter are the latest technology whether we accept it or not..
If anyone believes there is a better filter for the SS then please do recommend it with research details so we can have a read.

With all the dyno tunes done on my SS with the rapid bike evo, the autoadaptivity function trims the maps richer and has never requested a leaner trim. That suggests to me that the sprint filter is certainly not constricting the airflow.

K&N have been running these exact same promotional lines for years. Literally hundreds of independent tests have been done on all manner of vehicles, comparing the generally stock paper filter to aftermarket alternatives all promising significant performance increases. Overall, no meaningful performance improvement is observed.

If you use the maximum air flow possible (even if it massively exceeds the engines requirements) as a criteria for an air filter, then as the 'study' that was referred to in this thread shows oil based foam and paper filters have the lowest maximum air flow. That is true. But they are still excellent air filters. What the report failed to say is that these filter types are the most effective at filtering dirt. That's why oil impregnated foam filers are widely used in dusty environments. And the humble paper filter is almost universally used by every manufacturer of all types of vehicles in the world, regardless of whether the vehicle is budget priced or massively expensive. Are they all wrong!

Thanks for your reasoning and rightly so. I am not sure I get the point though, are you saying the Sprint is not a good filter or is it that the article does not provide sufficient details. The Sprint filter is given to the user when they buy the race exhaust for the SS. If it was not needed then why would they do it.
