CNC ICV Elbow – Fix for ICV elbow vacuum leak E30 M20 engines

January 1, 2022

These CNC ICV elbows replaces your stock ICV elbow. The original elbow is press fit from factory and loosens over time. Once loose, you end up getting a vacuum leak and up until these there was no great way to solve the problem. Most people either try a glob of JB weld or silicone; eventually fail again and cause risk of material ingestion.

The CNC units use two viton orings to produce a reliable and serviceable seal.

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 anymore, so grab one now if you want one.

Price: $100 + $8 shipping globally via small packet air.
