ISR Performance - Universal Silicone Coupler - 2.25" to 3.00" Reducer

The ISR Performance Universal Silicone Coupler in 2.25" to 3.00" reducing format is built for boost. 4-ply reinforced silicone construction handles the temperature and pressure ranges of real performance use, and the reducing geometry steps from common intercooler piping sizes to larger throttle body or core inlet dimensions.

What It Does

Silicone couplers connect different sections of intercooler or intake piping at the joints, absorbing engine movement and providing a sealed connection clamped at both ends. The 2.25" to 3.00" reducing format covers the common case where you're stepping from intercooler core piping (2.25") up to a larger intake or throttle body inlet (3.00"). 4-ply reinforced construction handles boost pressure and heat cycling that single-ply silicone would fail under.

Fitment

Universal. Connects 2.25" outer diameter piping to 3.00" outer diameter piping. Use T-bolt clamps (sold separately) for boost-pressure applications.
