Hi,

University of Swansea made only the airflow test and pictures at electronic mycroscope and measured holes of each air filter. Read the total test here: https://issuu.com/sprintfilter/docs/...76f1b38/13?e=0

We support from many years 80% of MotoGP, Moto3, WSBK (World SBK), FIM Superstock 1000 Racing Teams. Our filters stop dust also into the Losail Circuit (Qatar).

We hope that these infos are enough for you, at the moment.......

This is MUCH more important on an H2 because the supercharger impeller is right after the filter. Grit, or anything else, will erode the rotor tips causing very expensive damage.

Hey SPRINT AIR FILTERS, question. Exactly how much R&D do you really do? I bought one of your filters from Brocks for a 2010 ZX10R and was stunned by how much smaller it was than the stock filter, surface area wise. Why do you make it so small?


Compared to say a DNA which has 1/3rd more surface area using their FCD technology.


Should I post pictures? I mean seriously if I am to take you seriously on the H2 filter please explain why the 2010 ZX10R Sprint filter is so small compared to stock and even much smaller than the DNA.

Can I suggest you withdraw your offer of " all forum members ".

It is most definitely my experience that the smaller the aperture is the better. Oiled up or dry seems to make little difference to my performance. I have known these things be re used and not even cleaned. The fact that it is not clean ( though desirable ) is no deterrent. Once they have been inserted too many times the edges will deform and a tight seal will not be possible. A sloppy fit with gasses escaping can result in the strangest of noises.

I'm interested in this too would like to see independent testing done.

I'd encourage reputable cos such as Sprint to work on performance products for the H2. The fact they're working closely with Brocks in developing the filter is all I need to know. I already bought the DNA but if Sprint can develop one that's equal to or better from a performance standpoint but also does a better job at filtering fine particles I'll switch it out myself in heartbeat.

Not sure who did this testing but interesting:

Sounds like you are describing your mouth with something in it.

Well done. Cigarette smoking is the answer. I left out the part of passing it around to your mates as smoking dope and owning an H2 don't mix .
