Re:correcrt spark plugs
If you go to www.ngksparkplugs.com they have a part finder you can use. Once you find out what spark plug you need for the stock engine just get 1 or 2 steps colder depending on how much horsepower your making.

BKR7e-11 I believe is the one you want. Is anyone here good at reading plugs.. What do these tell you?

Re:correcrt spark plugs
I think those look fine.
Those Iridiums???? BKR7E-11 is what you want. Hard to read (cant link full res pics :-\ ), but the 7 is heat range. http://a8.cpimg.com/image/F8/C5/1950...-016E0200-.jpg |
Re:correcrt spark plugs
Those are the stock platnum ngk.. the car was running horrible with them in. I switched over to autolite 3922 which is non platnum one range colder.. its running much better. I know the car is rich from the gas smell it has.. I hope to fine tune it soon. I think the platnums were too hot... if you look closely (you probably can't see it) The porcelin part kinda melted/glazed over.

Re:correcrt spark plugs
I know the platnum is bad.. I did say that I have non platnums now.
