I forgot what NGK spark plugs to buy... since I'm going to buy them as soon as someone replies to this thread, quick responses would be appreciated. It's been 20,000 miles so they need to be changed, and oh by the way, I buy COPPER spark plugs not platinum. I know they're NGK and 1 step colder, but I don't have the spark plug model number written down.

Thanks.

to answer my own question after looking through aim logs I found it...

HlH0501 (5:34:47 PM): yes definatly regap the plugs, I'd go one step colder NGK coppers if i weire you
HlH0501 (5:34:51 PM): BKR6E' s

 

those are the correct ones.

 

Stock number 2962, IIRC?

 

gap them to at least .30

 

Im sure you mean .030". And that is too small at 9psi on 1step. Id go somewhere near .036"

You want to drop about .004" for each 50whp you add.

I glad you replied, b/c I couldn't remember offhand what the ratio was...

 

yup. thats what im running. i gapped mine .045. oops oh well. ill get m next time around. before these plugs i was running factory, i guess if i had gapped them prop, i might have some better results , i guess next time around..

 

You guys with the 3.5's, remember the plugs are NOT the same as the 3.0L.

 

Thanks for the reminder Jim...

Always good to have that info on hand.
