Description Why is there not one good plenum intake for the E30 M20 engine for sale? Maybe this is where it begins. I’m sharing 3D files with everyone hoping someone with capable CNC machines and skills would want to make it. I already 3D printed it out and tried fitting it to the actual engine and it fits perfectly without much modification. This one was designed to fit perfectly with the E30 OEM brake booster.
Update 11/13/24 With the help of CNC Innovations, we have a perfect plenum intake for the E30 M20 engine!
