Solves header clearance issues
These worked great to solve the header clearance issues caused by the shorty stainless headers I installed on the '78 Camaro.

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.

Not the proper plug
When I ordered these plugs it stated they were the exact fit for my 1988 Corvette. When I attempted to intall them I noticed the plug I removed was different than the product received. After some research on youtube I discovered there are 2 different plugs used that year, One for aluminum heads and a different plug for the cast iron heads. Since I didn't install as soon as received they are non-returnable now. Be sure to do your research !!!

Description says it all.
I have a 70s small block chevy with stainless steel shorty headers. These plugs will make spark plug replacement easier.
