K&N's drop-in air intake filter is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance drop-in intake filter. These are very easy to remove and maintain. Turner Motorsport recommends this as one of the first maintenance/modifications you make to your vehicle after you purchase! 

K&N's drop in air filters allow increased airflow - dirt and particles stick to the oil on these filters, making them more effective than traditional paper filters in terms of protection. Additionally, K&N believes their filters are more efficient than paper filers - this means more oxygen getting into the engine, allowing vaporized fuel to burn more efficiently and increasing horsepower and fuel economy. The best of both worlds!

  • Covered by the K&N Million Mile Limited Warranty
  • Washable and reusable
  • Emissions legal in all 50 states
  • Will not void vehicle warranty

Looking to make loads of power on pump gas? Enter: water/methanol injection. Regardless if you're tuned for conventional pump gas, E85, or race fuel, use of a properly configured and integrated water/meth system will reduce temperatures, allowing you to make more power than on just conventional fuel alone. Select your engine-specific nozzles (which are standard 1/8" NPT and install in most aftermarket chargepipes), your tank to mount in the trunk, upgraded steel braided lines if you so choose, and some boost juice and you just need a management solution! Optionally, add a BMS FSB for JB4 integration!

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:

E36 3 series : 318i 318is 318ti
Z3 : Z3 1.9

This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

The Snow Performance Stage 3 Boost Cooler brings 2D mapped water-methanol injection delivery to your DI (direct fuel injected) and forced induction (turbocharged/supercharged) vehicle.

Bringing fuel pressure into the mix allows the injection curve to be extended past specific boost points for greater range/control. None invasive, the Stage3 Boost Cooler controller is designed to mount on the steering column or the dash so no additional gauge pods need to be purchased and functions as a boost gauge, water-meth controller and fuel system monitor all in one! Proven to reduce the air inlet temperature by up to 100 degrees and increase octane by 25points for maximum HP and cooling . Comes with adjustable Stage 3 water-meth controller, 4AN fittings, and stainless steel braided line to mount pump/tank in engine bay of vehicle.
