BMW E46 Air Filters

BMW E46 Air Filters Lackluster performance from a high-performance machine can only mean one thing: poor maintenance. Keep your car at peak operating levels by doing simple things like replacing your air filter. Stock BMW air filters are made from pleated paper. In some cases you can simply remove it from the car and give it a good shake or brush with a very soft bristle brush. But for heavily soiled filters a replacement is the only option. A lot of fresh air is crucial for your BMW's engine to make power. Don't let the filter be the weak link. We only offer OEM quality brands for air filters.

No-Toil Foam Filter Oil (for ITG Filters) Don't use harsh solvents like gasoline to clean your ITG on your Eurosport/Conforti intake kit (or similar foam filter element). This product is all you need to maintain your ITG foam filter, and is recommend for use with all Conforti Cold-Air Intake Kits.

When cleaning an ITG foam filter, ITG recommends using warm water and a mild detergent (simple dish soap is fine). Strong detergents and solvents can harm the foam, and cause the filter to break down. Once dirt, dust and debris are rinsed out of the filter, it should be re-oiled to ensure proper function of the filter. ITG recommends No-Toil filter oil, as it is safe to the foam filter media, and is completely waterproof. Drive with more peace of mind through heavy rain and puddles.

Please note, as this product is an aerosol, it MUST BE SHIPPED BY UPS GROUND. Sorry, this can not be shipped outside of the US/Canda.
