Spark confused

95boostedGSX · Jul 8, 2011

Hey everyone im trying to figure out a spark problem .Today i had my plugs gapped around .35, and when i got on it around 4000rpm the car pauses for a second then goes so i thought this would be blowout so i re gapped them down to .28 and i think the issue has gootten worse do i have the right spark plugs? they are BPR6ES do i need to have a different gap?

You mean .028", right?

BPR6ES is the stock heat range plug so they should work fine. I think the stock range is .028" to .032" but I'm not 100% sure (it does include that range at least which means you're ok). You may have a plug wire or coil pack issue.

I have a bigger turbo at 13psi would that make a difference?

If the problem got worse than you probably have bad spark plug cables. I ran .024 at high boost levels and .028 at low levels. You may want to go too .026. I also would run ngk BR6ES. The missing "P" is for non projected plugs. I always had lower issues with knock when running these plugs. They are usually used in motorcycle and marine applications.
