Brand: Pipercross Air Filters

Pipercross air filters have been used in every form of motorsport from Formula Ford to Formula 1.

This compact (7" L x 5.5" W x 3.5" H) filter is small enough to work on most cars even if the bodywork or air scoop is very close fitting. The three stage foam element draws air through the top as well as the sides to allow the greatest possible air flow for its size. The integral plastic base plate fits the Weber 32/36DGV carburetor and mounts the filter parallel to the valve cover on the Ford Kent 1600 Uprated and the Ford 2.0L SOHC Pinto engines. Simply place the included foam gasket on top of the carb top plate and drop the PX400 filter in place. Use the included O-rings and zip ties to secure the filter to the carburetor using the clips at each end.

The economical PX400 filter is not intended to be cleaned and re-oiled. It should be replaced at each engine rebuild, or after two racing seasons. For a similar but more durable filter that is designed to be re-used, we recommend the Pipercross PX300 Air Filter for FF1600 (Part No. 1265-001).

If the bodywork cuts into the space needed for the air filter, the filter will easily deform for clearance without adversely affecting airflow.

Pipercross PX400 Filter


I am using this filter on a VW Beetle with a single center mounted Weber 38/38 sync style carburetor. The filter fits great and even though I'm not using it on a Formula Ford, the install still went fairly smooth. The biggest challenge I one might face with this filter is where to run the wire ties/o-rings to hold it on. However this is also one of my favorite aspects, no more wing nuts or goofy metal clips!

Must Have For The Serious Tuner


The Innovate Widebands are excellent. I had been using an older model in my MR2. However, I recently got into seriously using Weber carbs. I can tune them well by ear and reading the plugs but the new Innovate wideband air fuel guage let me see what was going on as I drove tbe car under various conditions. Because of this I was actually able to run leaner jets thus saving gas and improving power. The gauge alao lets me datalog to a laptop. The kit was extremely complete.

Very difficult to install on a formula car


Very poor directions on how to actually mount the filter along with two o-rings and a couple of cable ties makes for a real amateur looking set up. I ended up modifying it to fit by Ramair unit and worked pretty good but a lot of work. Bring back the Ramair filter!
