Prevent water, mud and sand from congesting your air intake system with the aFe Pre-Filter. This aFe Pre-Filter slips right over your performance air filter, adding an extra layer of defense against moisture, grime and other roadway filth, extending the cleaning interval of your aFe filter. Water is repelled by the proprietary hydrophobic treatment to the Pre-Filter�s polyester fabric, and the pre-filters uniformly spaced micron holes prevent debris .005� or larger from passing through. Best of all, using the Pre-Filter does not significantly diminish your air filter�s performance�the smooth rush of oxygen keeps rolling right into your engine. Visually, the Pre-Filter blends in seamlessly with your aFe Cold Air Intake System and other components under your hood.

This particular pre-filter is custom sized to fit the following aFe Intake Kits:
54-10171 (E36 6 Cylinder)

Built for performance and show, the Typhoon Air Intake System is a free-flowing mandrel-bent aluminum tube induction system designed to fit many sport compact performance vehicles. Each kit is proven on a rear-wheel dynamometer to increase horsepower and torque. Typhoon intakes come in one of three designs; cold air intakes (CA), short ram intakes (SR), or complete cold air (CCA) intakes which can be configured as either a cold air intake or a short ram intake. Available in an assortment of powder coated colors and polished aluminum, these kits are sure to please in every way. They come with an oversized High-Flow conical air filter designed to provide increased surface area and dust capacity. This extra surface area provides even more airflow at lower restriction than a standard K&N O/E replacement filter that is limited to the size of the factory air box. The oversize air filter also captures more dirt increasing the service life before a cleaning is required (up to 100,000 miles).

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!
