Hey, I read all the previous posts on this issue...and I am finding that people are giving mixed info. Which is the correct setup??? NGK BUR7EQ - trailing or Leading
NGK BUR9EQ - trailing or leading?

Rotary Performance has the BUR9EQ listed as the trailing plugs....but here on the forum people have said that its OK to use 9's as all four plugs...why would you use the trailing as all four???

Next question...where besides "options auto salon online", can i get MSD wires? I did a yahoo search and came up empty.

I recommend (turbos) FC's to run all 9's cause:
1) It's easier to buy all 9's rather than for both 7's and 9's.
2) The leadings fire twice as much, and running 9's in the leadings will give you longer spark plug life for the leadings.

Unless you do a LOT of stop&go driving, you can run all 9's in all four holes.&nbsp You don't have to worry about running 7's in the bottom holes and 9's in the tops.

What about a retailer to get the MSD wires from?

 

MSD stuff, you can't beat Summit Racing.

I don't think it'll show up on their online catalog, so call them up for your application.

Don't use Jegs! they cancelled my order and didn't tell me. I waited two weeks untill I finally called and they said "Oh, sorry; your order was cancelled two weeks ago"

 

What the hell is Jegs?

and...will summit have the plugs too?

 

Spark plugs can be bought from the local auto parts stores.&nbsp If you got a Kragen/Schucks/Checkers or Pep Boys, they seem to have the best price on the NGK spark plugs.
