give us some spec on the motor it really depend on compression ratio nitrous and type of fuels you might need a colder plug than stock or what your using

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... |
