Product details
These CNC ICV elbows replace your stock ICV elbow. The original elbow is press fit from the factory and loosens over time. Once loose, you end up with a vacuum leak — and up until these, there was no great way to solve the problem. Most people try a glob of JB Weld or silicone; it eventually fails again and risks material ingestion.
The CNC units use two Viton o-rings to produce a reliable and serviceable seal.
I initially made one for my own use, and many asked that I do a larger run — and I have, 100 units to be exact. Once sold through, I’m unlikely to be making any more, so grab one now if you want one.
Pairs with the CNC throttle body booster side elbows — the bundle options below ship everything under a single shipping charge.
Price: $100 + $8 shipping globally via small packet air. Bundles ship for the same single $8 charge.
