N62 Secondary Air Injection Repair Tool

The tool allows the user to penetrate the secondary air plenum via the outside of the cylinder head. This exposes the individual 3.9mm air injection holes in each port. After clearing the small air injection holes, a tap fixture allows the user to plug the plenum entry holes with stainless steel plugs. Check out the video!
