Just pulled out BKR5E spark plugs??
 

I decided to swap out my plugs today and to my suprise all the plugs were BKR5Es instead of the recommended BKR7Es. Is the 5 series hotter or colder?

two steps hotter.

i lied before, then edited.

One step. he's got a '99 so that's OEM. Get BKR6Es.

Already installed 7's guess i'll have to run them and see what happens.

You want one step colder than stock usually though right?

1 step for every 75-100 hp or so. 2 steps shouldn't hurt.

You want to run the hottest plug you can without detonation.

I found my 1st answer to my question...
BKR7E...
for the stock turbo setup?
Gap? .037?...
thoughts?

.03-.035"

The BKR7E is already pre-gapped at .035", I believe. The BKR7E-11 is pre-gapped at .043" (the "11" means 1.1mm, or about .043").

Thx., .035 GAP... I'll dbl check them.

Hrm. I grabbed BKR6E-11... How hard is to re-gap them? I bought a feeler tool... Do I just kinda squish the tip of the plug until the gap is right? Maybe I should take 'em back and trade 'em in for some non-11's. It's just a mile up the street.

Just squish it until it's right. I'm forced to run .024-.025 gaps on my plugs since anything higher will blow out with boost.

I need cops :(

Are you sure your dwell settings are right?

What are the symptoms of spark blowing out?

i'm using the same plugs as u (bkr6e-11) and i just used a gapper to set them at 33... pretty easy,
