At Pipercross we have been making high performance air filters for the motorsport and domestic market for over 25 years. Based in Northampton, England, we are situated amongst some of the biggest names in motorsport engine design and manufacturing in the world.

Over the last 25 years, Pipercross performance air filters have helped many race teams win major championships on the British, European and World stage. The development work carried out with these teams and constructors have enabled us to produce some of the most technically advanced filters on the market.

Pipercross air filters are Original Equipment on Triumph Motorcycles.

No other performance air filter manufacturer can boast such a wide ranging application list and dedication to the development of new kits for road and competition.

Why use a foam air filter?
Pipercross air filters consistently outperform paper and cotton-gauze rivals to supply air to the engine - even when dirty! This is thanks to the multilaminate construction used in every Pipercross performance air filter. Layers of varying porosity foam all work together to trap different sized particles.

Race Specification Air Filters
Unique to Pipercross, we also offer a range of race use only motorcycle air filters with a specification designed to maximise airflow and performance. Fuelling modifications are necessary to take advantage of the increased airflow and to prevent damage to the engine.

Performance Benefits
Designed to provide a dramatic increase in airflow over a standard paper air filter whilst still retaining the highest level of engine protection, a Pipercross motorcycle air filter is the last air filter you will need to buy for your bike.

Pipercross motorcycle air filters have been repeatedly tested on many different motorcycle configurations and the results speak for themselves. An increase in both power and torque without the need to modify fuelling, all by simply replacing the air filter unit.

Proven Results
Through extensive research and testing using the SAE J726c air cleaner test, we have developed the perfect combination of filter density and thickness for each layer within the air filter.

Where Pipercross filters are impregnated with the dirt retention additive, the filtration performance is greater enhanced as the additive helps the foam to swell, opening the cells whilst providing a "sticky" layer to hold more dirt. This greater dirt capacity translates to longer service intervals, saving you time and money.

At Pipercross, our performance air filters are also tested on independent state-of-the-art engine Dynamometers and the results speak for themselves with the graphs below showing both horsepower and torque figures in comparison to the standard air filter and intake system.
