     Upgrade your stock rubber plenum to runner couplers to high performance silicone. Our couplers are made from nylon reinforced silicone that will never crack or fail. They seal very well and are a must for serious forced induction cars. These couplers are rated to an incredible 100 psi so you won't have to worry about them on even the most hard core applications.

      We have found that the stock rubber couplers only last a year or two at best before they develop cracks as a result of boost pressure. These cracks are dangerous because they cause the effected cylinder to run lean when off boost. Plus they rob a lot of power when the boost is on.

     These GTV6 & Milano couplers come with 12 Stainless Steel Guarded clamps.  The Spider couplers come with 8 Stainless Steel Guarded clamps.   These clamps will NOT damage the couplers unlike the conventional worm gear clamps found at autoparts stores.
