The original rubber couplers for Porsche 996 and 997 GT3 models have become increasingly costly and hard to source, and many enthusiasts opt to avoid them for high-performance applications like hot rods or track cars due to their limited heat resistance.

Our precision-molded OEM+ silicone sleeves are the perfect direct replacement, offering double the temperature resistance of the original rubber couplers along with an enhanced appearance. These high-quality sleeves are essential for replacing worn-out rubber parts and are ideal for air-cooled hot rods undergoing a modern DBW (Drive-By-Wire) conversion using a GT3 intake plenum.

This set includes four silicone sleeves
