At PMB Performance, we’ve spent over 20 years perfecting Porsche 914 restorations, and our nearly two-decade partnership with 914Rubber makes us the top retailer for their SKUs, carrying more than any other.
If your 1970-72 914’s airbox is failing—causing poor heat, weak defrost, or air leaks due to brittle seals and worn components—our 914Rubber Airbox Rebuild Kit is the complete solution for early cars without the factory grille. Tailored for 914s from 1970-1972, this all-in-one kit (one per car) includes everything for a full overhaul: housing seal, air flapper seals, airbox top seal, fan motor seal, airbox hoses, drain hose set, bowden cables with grommet, climate control knobs (two black, one red), plus all necessary hardware—clamps, screws, bolts, washers, omega clips, and more.
Crafted to OEM specs, the seals use high-grade EPDM rubber to resist heat and cracking, while precision-molded hoses ensure airtight flow. Our tech experience highlights the importance of inspecting the air flapper valve alignment and lubricating bowden cables during install to restore crisp climate control.
Trust PMB Performance and 914Rubber to revive your 914’s heating and defrost system with unmatched quality.
