Seamless Intake Integration

When upgrading to a larger throttle body, the connection between your intake pipe and the throttle body is critical. The Grams Performance 3.15-inch to 3.00-inch Silicone Reinforced Reducer Coupler is designed to make your installation process as smooth as possible. Specifically crafted for owners of the '06-'11 Civic Si, Subaru BRZ, Scion FR-S, and Toyota 86, this coupler eliminates the struggle of trying to stretch original, smaller-diameter hoses over a larger 72mm throttle body.
