57i Induction Kits
The 57i-kit is the entry level K&N open air filter kit for vehilces equipped with a fuel injected petrol engine or a diesel engine. It includes a K&N High Flow open air filter (including the 10 Year/Million Mile Limited Warranty) which replaces the OE air box, resulting in an increased air flow and hence an increased engine performance. Each 57i-kit is developed for a specific application; therefore, each kit includes all necessary brackets, hardware and clear, illustrated installation instructions to help you fit the filter to your car using common hand held tools. When needed, the kit includes a cold air feed hose, a custom designed intake tube or MAS adaptor. It is for this reason that some applications have additional notes in the 'comments' column; where specified, the kit only fits the indicated version of the car, or excludes a specific version. Please do not attempt to install any kit on an application not listed to prevent any problems
