Air filter DNA RACING for original air box on quad HONDA TRX 400 EX from 1999 to 2005

Here is the DNA filter R-H4AT05-01 for your HONDA TRX 400 EX from 1999 to 2005.

The flow rate of this DNA Fcd filter is high, more than 2 times more than the standard paper filter! This DNA filter is equipped with advanced FCd (design Full Contour) DNA technology. The installation of the filter is very easy, just follow the information in the workshop manual HONDA .

This DNA filter is designed as a high flow filter for on-road or off-road use. We all know that an original quad runs a bit too rich for origin for better protection in conditions never reached in our countries (use of engines in very hot countries, bad gasoline low-end and old. ..).

This is why we can afford even with a carburation / injection of origin to opt for a freer air filter. DNA FILTER filters are washable filters that allow more air for better performance with poorer AFR ! They last the life of the bike because you just need to clean them and then re-oil them.

It arises in place of your old air filter without any modification, ideal to gain performance without difficulty and at a lower cost.
