Pipercross Air Filter

Something new we'll be trying this year is the Pipercross racing air filter. Based out of the UK, Pipercross has been in business for 28 years. Most people here in the states haven't heard of the name, but a couple bigger name teams such as Rizla Suzuki and the Ducati Xerox team are using the Pipercross filter with very good results. Recently Pipercross is making a push here in the U.S.

Knowing how I am, our next trip to the dyno will include a comparison between an OEM, BMC and Pipercross air filter. I think the results will be noticeable, but the dyno is always the best way to confirm. A few notes about Pipercross include:

- In dust-flow testing at 150CFM, the Pipercross filter went nearly 4 times longer at the same dust flow rate before suffering major pressure drop. In fact, at the point in testing where cotton gauze was having a big drop in airbox pressure, Pipercross was still over 90% effective flow rate. (24 mmWG drop at 15 minutes versus 220 mmWG drop at the same point for cotton gauze).

- Compared to the cotton gauze filters (KN, DNA, BMC, etc) their foam is able to retain more fine particles; over 4% more fine particle filtration at 98.68% versus 94.60% for cotton gauze. Sacrificing particle filtration for more airflow has always been a challenge for the brands that use cotton gauze media.

- In terms of total "net" dust particle retained, Pipercross had nearly triple the total dust retention during the course of the test, so not only did it flow as well as other "top brand" race filters when clean, but when they became clogged, it kept flowing air while letting less dust through to harm the engine internals.

- New to the US market, but one of the most dominant air filters in the European market, Pipercross gives you increased power and torque, is easy to clean/reuse, and carries a lifetime warranty.

I'll post some more info after we make our trip to the dyno. If anyone would like a lead on one, let me know.
