Features & Product Details

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.

Looks good 3 years ago

It was a really good replacement for the stock one. It is a bit bigger than stock so it'll take manovering or cutting to make it work... I just manovered. It looks nice in the bay. I drive 05 wrx hatch

  • Q: Cobb vs Perrin coupler.  chrispy bacon5 years ago

    Why is the Cobb coupler 12$ more expensive than the Perrin one when the Perrin one is a 5 ply and comes with T clamps? how many plies is the Cobb coupler? thanks
  • Q: Compared to Perrin?  astaticwinter6 years ago

    Can anyone compare this to the one made by Perrin? ( Same piece, but I've read in those reviews that the Perrin version is shorter than stock. Not that it's a major issue, but I'd rather go with the one that fits the best. Perrin is cheaper, and does have nicer clamps though...any suggestions on which to go with?

      A:  They are both going to be excellent pieces and the length difference is very minimal. You can not go wrong with either selection! :)
