Spectre Performance® 47621

Extraflow Custom Assembly
Average Rating: (0 reviews)
Spectre's 14 inch by 3 inch tall Extraflow air filter assembly is designed to fit throttle body injection assemblies and carburetors with a 5-1/8 inch neck flange. Featuring a zinc plated 1-1/4 inch drop base for increased hood clearance, this assembly requires 2.9 inches of clearance above the carb flange when installed. This assembly includes an ExtraFlow filter lid, which increases filter area and allows it to outperform standard closed lids. Available with black synthetic media, our Extraflow assemblies are designed to provide greater performance than ordinary paper filters by increasing air flow into the engine. Full overview
