914Rubber Late Airbox and Wiper Shaft Seal Kit for Porsche 914 (1973-76)

Upgrade your Porsche 914 (1973-76) with the 914Rubber Late Airbox and Wiper Shaft Seal Kit, brought to you by PMB Performance. With 20 years of Porsche 914 expertise and a nearly two-decade partnership with 914Rubber, we’re the leading retailer of their SKUs, offering the widest selection available. This kit delivers precision-engineered seals to restore your airbox and wiper system, ensuring peak performance and weather protection.

Airbox Seal (Part #914.571.129.10) and Grille (Part #914.571.131.10): Unlike the extruded seal used in 1970-72 models, the 1973-76 914 airbox features a molded top seal and grille assembly. Crafted from premium silicone, the seal resists temperatures up to 250°F and withstands UV and ozone exposure for lasting durability. It ensures a tight seal between the air inlet box and body, preventing unfiltered air from entering the intake, which can reduce engine efficiency by up to 5%. The kit includes three PVC drain hoses (Part #PCG.571.900.00) to divert water, protecting the airbox from corrosion. For installation, secure the seal with 914Rubber’s Omega Clips (Part #914.571.905.10, six required) and clean surfaces with a 50:50 isopropyl alcohol mix to ensure an airtight fit.

Wiper Shaft Bushing Set (Part #901.628.924.00, 901.628.923.01): This set includes male and female elastomer bushings for both wiper arm mounts, replacing worn or cracked originals. These bushings minimize vibration, reducing wiper arm play that can lead to uneven wiping or motor strain. The male bushing fits below the nut, while the female bushing sits above the flange washer for a secure seal. Pair with 914Rubber’s Wiper Shaft Caps (Part #901.628.926.00, two required) for a full refresh. Installation tip: Torque the wiper shaft nut to 8-10 Nm to prevent over-compression, a common issue we’ve seen in our shop that can shorten bushing life.
