That's right...you didn't mis-read the title. Pipercross has released their air filter for the new 2011 ZX10R. And the best part, they are IN STOCK and ready to ship out :)

Check out the info below (yes, I know it's for a 09 GSXR1000, but we will hopefully have Dyno's specific for the ZX10 soon), but Pipercross has been boasted some great hP gains just by changing out the filter even over BMC and K&N. Just CLICK HERE to go to the listing on the website.

In July 2010 Bazzaz Performance did a head-to-head dyno comparison test using a 2009 GSXR1000 equipped with their fuel management system. They compared a BMC RACE filter to a Pipercross RACE and Pipercross STREET filters. The results? BOTH Pipercross filters beat the BMC Race filter in torque and horsepower! On several bikes, you can expect to see gains well over +5hp, and on the new BMW 1200GS dual sport, an amazing 8.5hp at the midrange.
Cotton gauze filters (K&N, BMC, DNA, etc) act much as a progressive-stage screening process. At some point, particles cannot penetrate and fill that "gap". Now we're talking tiny particles, but it adds up very quickly. If you've every poured sand through a screen, a couple grains stick, then more, then more, and you have a sand pile on top of the screen and NOTHING gets through.

Pipercross open cell polyurethane foam is wetted with specially developed dirt retention oil. The "sticky oil" is suspended in the path of the dirty air on the strands of the web-like cell structure of the foam. This makes it difficult for small dirt particles to pass through the depth of the filter without sticking to the strands. Larger particles are trapped if they are bigger than the distance between the cell strands themselves.

As the outer wetted strands become loaded with dirt particles and no longer sticky, the wetted strands downstream continue trapping dirt, until the entire foam thickness is utilized. Also, as dirt particles build up on the strands the space between strands decreases, further increasing the filter efficiency by trapping the smaller dirt particles that initially could pass between the strands in a clean filter. This approach prevents the surface loading and air restriction that single-stage paper filter elements experience and consequently extends the service life of the air filter element. Finally, when the filter is sufficiently dirty to stop trapping small particles and clogging reduces airflow, it can conveniently be washed, re-oiled, and re-used. When oiling a foam air filter, use as little as possible, but do get adequate coverage.

Pipercross filters are constructed of a multi-stage filter design. Stage 1 is the coarse foam layer that stops larger debris from clogging up the stage 2 filter layer. Stage 2 is the fine pore foam to collect smaller particle that the stage 1 layer missed. In essence, the finer layer of foam stops the fine particles from entering the combustion chamber, where the coarser layer of foam acts as a dust/dirt trap. Restricted airflow only starts when too many of the millions of tiny "routes through the strands" becomes blocked (think of your arteries and cholesterol versus a blood clot).

This is also why the race spec filter works so well. Instead of simply having "more/larger holes in a screen" which results in depleted particle capture, the race filter simply has less/thinner coarse dust trap foam. So the filter offers an overall higher level of airflow, but for a shorter amount of time before more of the particles are filling the space between strands and lowering flow efficiency. This IS NOT POSSIBLE with cotton gauze filters, of any brand.
