Spark Plugs
Does anyone here use NGK copper in his GSR? I have a 94 GSR 4d and it's about time to change spark plug. Manual says NGK platinum but I am planning to use copper and change it every 12-15k. Just want to make sure someone has done it before and it wouldn't hurt the engine.
Thanx.

Stick with the coppers. They're cheap and work great. Platnums are expensive but they do last longer.

There was a big discussion about this before the big crash, and I believe the general concensus was that coppers are the way to go. They do need to be changed about twice as often (I think) as the platinums, but I believe they only cost about 1/4 as much. There was some talk about copper producing a better spark since it is a better conductor than platinum, but I don't think it would make any difference. Copper :thumbup:

I think copper plugs are recommended for non-vtec engines and platinum plugs for vtec engines. Just want to know if using copper in a vtec would do any harm. Anyone?
