Why replace the factory standard air-box?
Standard air filters along with their housings are designed to perform a satisfactory filtering job whilst keeping noise levels down. Ideal if you’re an old lady going to the shops – but not if your interested in performance! Getting rid of the air box and replacing the standard paper filter for a sexy cone filter not only looks great but performs so much better.

What’s so good about a K&N?
K&N air filters are designed to achieve high, virtually unrestricted air flow whilst maintaining excellent filtration levels. The secret to their success lies in the unique high flow media, which consists of 4-6 sheets of oiled cotton gauze layered between aluminum mesh. The result is an air filter which allows dramatically more air into the engine, is washable and reusable, and will protect your engine for the life of your vehicle.

How does this improve performance?
You’ll have seen cone filters used on thousands of race cars. They’re there for a reason! A cone filter allows far greater volumes of air flow into the engine. More air provides more oxygen for combustion, which gives greater efficiency and more power.

What about the sound?
A cone filter will create an awesome induction ‘roar’ when you apply full throttle. In general driving there will be no discernable difference in noise level compared to a standard air box – It’s only there when you put your right foot down! Factory standard air boxes are designed to muffle the sound. That’s fine if you want to listen to Radio2 whilst visiting the garden centre! As a performance enthusiast you’ll crave the induction sound that you get when the throttle’s wide open!

How does this noise compare to other induction kits?
A cotton gauze filter (like this K&N) will tend to be slightly louder than a foam element filter. It’ll give a good ‘roar’ on full throttle. The exact noise level will depend upon the amount of sound insulation in your car.

How do I fit it?
Fitting varies greatly from car to car. In most cases the job can be carried out in around 20-30 minutes using ordinary DIY tools.
