All engines need oxygen to produce power and optimising your engine’s intake system to ensure that the engine has all the cold air it can take in and use, will help to keep it functioning efficiently and generating the most power possible. One of the simplest performance upgrades is to replace the original paper filter element with a free flowing performance air filter from a brand like K&N Filters, ITG or BMC. Normally made from oiled cotton or oiled foam, a performance air filter element drops right into your original air box, and allows more air through than the original paper element meaning your car’s factory air box will perform as well as it possibly can.
The next step is a complete induction kit. By replacing the original air box, a much bigger filter element can be used. Normally the flat panel will be swapped out for a cone offering more surface area and this may be in an enclosed cold air feed, behind a heat shield or simply in the same supply of cold air the original air box was using. An open air intake will probably sound better, but an enclosed system will ensure the best supply of cold air into the engine. Pipework to and from the air box may be replaced, depending on the exact type of intake chosen.
Which option of air filter that you go for will depend on exactly what you want out of an intake. If it’s induction noise, then an open cone air filter is definitely the way to go. If it’s performance then an option with a cold air feed will work best. Whatever your preference, we’ve got a range of the very best performance air filters and induction kits from leading manufacturers trusted around the world including Revo, Pipercross and AEM, all suitable for a variety of makes and models.
