Solves clearance problem.
These Accel spark plugs solved problems I was having regarding clearance with my headers wrapped with Titanium Heat wrap on my 350 engine in a 1979 Corvette. Before using these Accel plugs I could just barely get socket over plug to tighten as needed. These plugs solved the above problem.
