I will be doing some routine maintenence on my GT next weekend. I am going to clean the plugs, and re-gap them. My question is: Should I use Seafoam before, or after the plug cleaning? Thanks- SF
I don't think it would matter one bit. I would do the plugs and then the Seafoam since the engine should be cool when the plugs are removed. I've had better results when using Seafoam on a warm engine.
:Word:....not worth the hassle just to stick used plugs back in there. Ditch the Platinums and go with a set of Copper plugs while you're at it.
I have minimal mods; What kind of plugs would you guys recomend? And also, are there any downsides to copper plugs? And what are the advantages?
autolite 764, or the NGKtr6? someone will have to confirm the NGK, but i know the autolites are 764s copper top and bottom. they spark harder, and better for performance the platinum... they do wear out sooner, 30-50k instead of 100k, and they cost about 1/2 as much. torinalth
Without an sort of power adder, just go with a set of AWSF-32C's. The copper plugs will burn cleaner than the factory platinum ones and will perform marginally better as a result....not to mention they're about 1/3 of the price. The only advantage the platinum plugs have over the copper units, is their long life. Platinum plugs are good to 160,000km and copper should be changed about every 50,000km.
Seafoam before you change the plugs. Its definatly possible for Seafoam to fowl a plug... think of all the nasty crap thats being burnt off at once.
