K&N High-Flow Air Filters    
The best known and most highly regarded high-flow air filter range, K&N filters have stood the test of time.  The range is divided into two types: replacement high-flow elements designed to fit in the original air filter casings, and high-flow air filter assemblies to replace the entire original assemblies. K&N filters are designed for long life fitment, and are not replaced when the car is serviced; they may simply be cleaned and re-oiled using the service products listed here.
Because of the increased air flow through a K&N filter, some adjustment of carburation may be necessary to realise the full potential in increased efficiency.
