I need to upgrade my spark plugs in my CJ5 Sand Racer, 401
Currently I am using Accel 116.

What's everyone using these days ?

When I had my 1967 Plymouth Barracuda with a 383 Commando engine at 11.5 compression and an Accel 80k volt coil...the only plugs that would hold up were the NGK solid copper core...
All the other brands would break down within a couple weeks and the NGKs would last at least a year..
Needless to say ...I run only NGK in every vehicle I have...
