Pro-Flo Air Filter Cone 3.70 Tall Blue/Chrome

The Pro-Flo Air Filter Cone 3.70 Tall Blue/Chrome from Edelbrock is a universal clamp-on conical air filter designed for enthusiasts and tuners seeking improved engine breathing and airflow consistency. Built for carbureted and fuel-injected engines alike, this intake component replaces restrictive factory air boxes with a direct-flow design that promotes cooler, denser air charge into the combustion chamber. Whether you're building a street machine, classic hot rod, or upgrading a daily driver, this high-visibility blue and chrome filter cone delivers both functional performance gains and eye-catching underhood aesthetics.

This conical air filter element features a 6-inch base diameter tapering to a 4.75-inch top outer diameter, with a compact 3.7-inch height that fits tight engine compartments without sacrificing filtration surface area. The cotton media construction provides excellent flow characteristics while maintaining effective particle capture across a wide range of RPM conditions. A universal 3- to 4-inch inlet accommodates most carburetor flanges and intake manifold adapters, making installation straightforward with standard hose clamps. The durable chrome-plated steel base and vibrant blue filter housing resist corrosion and are engineered to withstand sustained high-velocity airflow without deformation or seal degradation.

Mechanics and engine builders favor Pro-Flo cone filters for applications requiring reliable performance without complex mounting brackets or proprietary hardware. Installation requires only a compatible intake adapter (sold separately) and basic clamps; no modifications to the original fuel or ignition systems are necessary. This filter suits street and strip applications equally well—from mild carburetor upgrades to turbocharged conversions—provided inlet diameter falls within the stated 3- to 4-inch range. Weighing just 1.34 pounds, the Pro-Flo design minimizes underhood weight while maintaining structural rigidity for prolonged durability.
