Moroso's unique radiused air inlet design equalizes air pressure past the boosters for uniform air flow
Radiused air inlet is stamped into air cleaner base to reduce overall height
Back to back dyno testing proves a gain of over nearly 10 horsepower over running no air cleaner at all
Air Cleaners with 3" element have an overall stacking height above the carburetor lip of only 2-1/2", while 5" filters have a 4-1/2" overall height
Fits all Holley®, Carter, Rochester, and Edelbrock carburetors with 5-1/8" dia. necks
Includes matching wing nut and PCV adapter
