914Rubber Air Inlet Box Grill and Seal Set for Porsche 914 (1970-76)
Optimize your Porsche 914’s fresh air system with the 914Rubber Air Inlet Box Grill and Seal Set, compatible with all 1970-76 models. PMB Performance, with 20 years of Porsche 914 restoration expertise, has partnered with 914Rubber for nearly two decades to deliver top-quality parts. As the leading 914Rubber retailer, we sell more SKUs than anyone, ensuring you get precision-engineered components like this grill and seal set, designed to OEM standards.
This kit includes a reproduction grille (Part #914.571.131.10) and a molded top seal (Part #914.571.129.10) for 1973-76 models (VIN #24929 and up), though it fits all 914 years without modification. The grille, made from corrosion-resistant stamped aluminum, prevents debris from entering the blower motor, extending its life by up to 20%. The EPDM rubber seal, with a tensile strength of 10 MPa, is UV- and ozone-resistant, maintaining flexibility from -40°F to 248°F. The kit also includes a foam sealing ring (Part #901.571.922.00) with adhesive backing for a tight seal between the fan housing and air box. One set is required per car, ideal for air box rebuilds or climate control refreshes.
Why this set? Early 914s (1970-72) lacked a grille, and degraded seals allow debris and water to compromise the blower motor, reducing cabin airflow by up to 30%. Introduced mid-1973, this grille and seal combo ensures clean, efficient air delivery. We’ve used this set in countless 914 restorations, from daily drivers to track cars, and it’s a must for maintaining heater and defroster performance. A customer shared, “My ’74 914’s heater works like new after installing this kit—no more leaves in the fan!” Installation is simple: remove the old seal, clean the air box with isopropyl alcohol, install the grille, and apply the new seal with even pressure. Secure clips (Part #914.571.905.10, not included) at 2 Nm torque. For 1970-72 models, the molded seal replaces the extruded version (Part #914.571.904.10) without issues.
