Remove your dull OEM top mount intercooler coupler, replace it with a PERRIN Throttle Body Coupler Kit, and give your engine bay a touch of style.
The PERRIN TMIC Throttle Body Coupler Kit replaces your factory coupler with our high-gloss, vibrant color hose that looks and works better. Our silicone couplers are made from fiber-reinforced 3-ply silicone tubes. Our high-strength reinforced silicone's multi-layer design is capable of withstanding extremely high pressures and temperatures.
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.
The PERRIN Throttle Body Coupler upgrades your car’s old rubber connector with a durable, reinforced silicone one that performs and looks better. It’s tough enough for high-performance driving and extreme engine temperatures.
