The factory throttle body coupler is one of those components that fail over time and mileage. What happens, is the inner fibers come apart which will eventuall cause a boost leak. So if you have noticed a sudden loss of engine power, and everything else checks out, then it could very well be the throttle body coupler. The COBB Tuning Throttle Body Coupler has been made from mutli-layered heat resistant silicone fibers that will provide you with performance for years to come.
This coupler will come ready to install with a supplied pair of worm clamps.
