ISR Performance Universal Air Filter 3" inlet (clamp style)

The ISR Performance universal air filter with a 3 inch clamp style inlet is a high flow cone filter that slips over any turbo inlet or intake pipe with a 3 inch outer diameter. It is the filter supplied with ISR intake kits and a simple replacement or upgrade for any 3 inch intake that currently runs a worn or restrictive element.

Filter facts

• 3 inch clamp style inlet
• Cone shape with a large surface area for high flow
• Washable and reusable
• Clamp included

Where it works

Any application with a 3 inch outer diameter pipe or turbo inlet: SR20DET and KA24DE turbo setups, custom intake pipes, or a direct replacement for the filter in an ISR intake kit. Because it clamps on rather than using a flange, it is not tied to any particular vehicle.

Care

A washable filter can be cleaned and reoiled instead of thrown away, which keeps a turbo car breathing properly between service intervals. Inspect it regularly if the car sees dusty conditions or a lot of track time.

Installation

Slide the filter over the pipe, seat it fully and tighten the included clamp. Check that the filter does not contact body panels or hot components once the engine bay is buttoned up.

All ISR Performance products are designed for off-road use only.
