Brand: K&N Engineering
This cone-shaped air filter from K&N is designed to work in the 1983-85 Tiga Sports 2000 racecar air scoop, but it can be adapted to a wide variety of custom applications. The large inlet end is flexible enough to conform to an oval or rounded rectangle. The small end has a hole to allow debris to pass through the scoop.
Inlet: 6.12" Outside Diameter / 19.2" Circumference
Small End: 3" Outside Diameter
Effective Filtering Area: 230 square inches (enough for a 400 CID V8 revving to 12,000 rpm!)
