ABSTRACT:
An air filter having a tapered cylindrical filter member is attached to an engine air intake at its larger end and has an inverted frusto-conical member inside the opposing smaller end for reducing turbulent air flow through the air filter. The inverted frusto-conical member includes an air filter portion which may be the tapered walls of the inverted frusto-conical member, or the smaller flat end of the inverted frusto-conical member. A funnel inside the larger end of the tapered cylindrical filter member further reduces turbulence of the air flow from the air filter into the engine air intake.
