Pro-Flo Air Filter Cone 6.70 Tall Red/Chrome

The Pro-Flo Air Filter Cone 6.70 Tall Red/Chrome is a universal clamp-on conical intake filter designed for automotive enthusiasts and mechanics seeking improved engine breathing and filtration on modified vehicles. This versatile air filter element suits custom intake builds, street cars, and performance applications where a high-flow design enhances airflow without sacrificing engine protection. Available for immediate purchase, this filter cone serves as a drop-in replacement for existing air box systems or as a component in custom cold-air intake installations.

Engineered with premium cotton media and a durable chrome-and-red housing, the Pro-Flo cone delivers superior flow rates compared to restrictive OEM elements while maintaining effective particulate capture. The conical design maximizes surface area—standing 6.7 inches tall with a 6-inch base diameter and 4.75-inch top opening—allowing reduced intake restriction and improved volumetric efficiency. The 3–4 inch inlet accommodates standard clamp-on mounting systems, making integration straightforward on vehicles with compatible intake piping or tuning kits. Cotton media resists moisture buildup better than paper alternatives and enables safe cleaning and reuse, reducing long-term ownership costs.

Performance-minded owners benefit most from this filter when paired with upgraded fuel management, intake manifolds, or turbocharger packages where OEM filtration becomes a restriction point. Real-world applications include engine swap builds, naturally aspirated power builds, and street rod projects where air density and filter longevity matter equally. Universal mounting compatibility means verification of clamp diameter and inlet size against your specific intake tubing is essential; measure your system's internal diameter to ensure the 3–4 inch inlet specification matches before purchase. Once installed, expect noticeable intake noise and potential modest power gains—quantified by dyno testing on a case-by-case basis depending on overall engine tuning and supporting modifications.
