We made black 4-ply reinforced silicone couplers to replace the dried, worn out or possibly torn stock rubber couplers for the oem G35 intake pipe or Stillen Z tube. We even made an option to replace the upper coupler with one that fits the 75mm Hitachi ETB0021 throttle body that is a common upgrade for the VQ35DE.
Fits Stillen or OEM Z-Tubes.
Our new Compatibility checking feature is still being updated and revised. If you have questions about vehicle fitment, please contact us.
