I removed the plugs on my 92 and it had (Torque Master R6) plugs in it. I do not know anything about them.(Torque Master) Are they good or bad?? Thanks!!

Personally, I have never heard of them. I would replace them with NGKs.

I agree find the appropriate NGK iridium plug for your heat range and enjoy.

I ran across this thread from years back on a google search, as I'm currently shopping C5's and doing some research - had a couple notes:

1) Torque Master spark plugs are warranted forever - and honestly - don't wear out or degrade in performance.

2) a torque wrench isn't the worst idea for inexperienced hands and especially in aluminum heads.

3) did I miss anyone mentioning using anti-seize compound on the threads? For Pete's sake, kids - it's not that out of the park to the consider.

Enjoy your rides and be safe! - Aaron

My experience w using anti-seize, at least on LT-5 heads, is that the plugs will need constant re-torque. I use a dab of oil on the threads. And yes, very helpful to use a torque wrench when installing plugs. They only need about 19-21#.

Sorry, cant get on board with that.... there is no spark plug or primary ignition component that will never degrade over time. Constantly sending 40-50k volts through coils, ignition wires and spark plugs eventually wears them out. After driving several thousand miles take a look at the electrode on a spark plug and notice its sharp edges are now rounded off... its beginning to wear. There is no magic pill or elixir for an engine that is an end all be all..... everything needs maintenance and replaced eventually.

Agreed. There is no "forever" spark plug.
