FEULING OIL PUMP CORP. BA Air Cleaner Kit - Black with Red Filter - '93-'99 Evolution Big Twin 5463

If you're running an Evolution Big Twin and want measurable gains in horsepower and torque without compromising reliability, the FEULING BA Air Cleaner Kit delivers the goods. The billet aluminum velocity stack optimizes intake runner length and air velocity for balanced, dynamic flow that scales with your engine's breathing capability—whether you're running stock or heavily modified cylinder heads. This is a bolt-on upgrade that's been flow-bench developed, dyno-tested, and track-proven to perform.

The high-flow reusable filter and convertible backing plate give you flexibility in how you route cylinder head breathing, while the engraved MADE IN USA construction ensures you're getting genuine FEULING engineering. Expect exceptional gains on ported heads, larger throttle bodies, and modified intakes—or solid, reliable performance on stock platforms.
