Hey guys want your opinion on something. I installed my MSD wires, coil pack, and NGK 4306 plugs gapped at .35 . When I drive in the morning now until the car fully heats up I'm getting a popping noise from my engine compartment. This noise only happens when I let off of the gas. What you think ?

 

what is the stock gap of the plugs. sure its not exhaust popping.

 

Burnout, my 4306 plugs came factory gapped to .052 just like NGK say's they are supposed to be. I did double check them carefully before putting them in but .035 sounds too tight.

I don't know if that would cause the problem you're describing but .035 just didn't sound right. I've also read a lot of posts in here saying to stay away from the MSD coil mainly because it's a waste of money rather than a poor product. It supposedly doesn't put out anything more than the stock coil.

This post below is straight from NGK's website.

I bought the coil for looks more than anything ..... I have been told by numerous people that a gap of .35 was the ideal gap for running stage 2, so that's what I went by .... I know when you buy the stage 3 kit it reccomends that gap.

And to answer srtbris......... [sm=pcwhack.gif]..... LoL... I'm not an idiot bro.

 

.035 is too small for s2. bring that up to around .040 or so.

 

Ya good call... I did that yesterday and since then no more noise.
