ISR Performance - Universal Silicone Coupler - 2.75" 45 Degree

The ISR Performance Universal Silicone Coupler is a 45-degree elbow in 2.75-inch diameter. Built from 4-ply reinforced silicone for extreme temperature and pressure environments, it's a direct fit for any custom intercooler piping, intake, or charge pipe application using 2.75-inch tubing.

What It Does

Silicone couplers connect two sections of piping in custom intercooler, intake, or boost piping setups. Angled couplers route piping around obstacles like the engine block, intercooler core, or chassis bracing without resorting to expensive custom-bent metal tubing. The 4-ply silicone construction handles the heat and boost pressure that lower-quality couplers fail under.
