CFM-Tech Injector Spacer for GM Tbi 4.3/5.0/5.7

The Injector Spacer installs between the injector pod and throttle body. It raises the injectors further out of the injector bores, but does not raise the air cleaner.

One of the biggest restrictions to air in the GM Tbi system is the placement of the injectors. Anything we can do to provide more airspace to the throttle bores, we will and have.
