hey if you are turbo now there is a diff. You should gap your plugs about .32 if running low boost anything higer than like 10 psi then go to .28 .

I have some friendsd doing .20 but on 20 psi on a 4g63 enigne, It shoould all be the same any engine though. I have mines gaped at .32 for now since running low boost

 

Man I have had mine turboed for 3 1/2 years and I have yet to find any plugs that will benefit my turbo kit. I also have the Hahn Stage 2 but I have heard that the only company to make any colder range plugs is Denso at @ $16.00 a plug. Are the BKR6E's any colder than stock?

 

i dont know but I just put those in and gaped to .03, and my car runs great now, no more cruising surge and even idles a little better, I used to have the bosch +4's

That's a nice gap...
A 0.028" gap is for 16 psi or more of boost.

dude 16 a plug that is a lot of money man look i kow this company that sells bkr7e's for our cars that are one range colder.

I bought 3 sets for like 40 dollars man or you can just buy one set like for 10 dollars..


http://www.philsinc.com./ that is the web site call them and ask them for this part #6097 that is the part # for the bkr7e


laterz hope it helps

 

Just go to Advance Auto and have them order NGK BKR7E-11. They're like $1.50 a plug.

 

Yeah, what he said... 16 a plug, f$k that! You should change plugs every oil change or every other... 16 a piece would kill you... the ngk's are the best i've used anyway, and the cheapest just about... upto 15psi, you should gap to .030, 15+ psi, gap .025. Thats straight from Len, cant get a better source than that just about, imho.

I believe that the gap is:
0.030" for up to 16 psi of boost and 0.028" for more than 16 psi...

 

2. "RE: plug gap with msd?"
In response to message #1

.030 up to 15psi or so, .025 at 20psi. That is the gospel according to Len (Ayala).

Anbody care to shed some light as to how I would go about getting some non-$16 plugs from Len?

Thanks for the help

Check the last paragraph from this link...
It doesn't matter which ignition system you use, the gaps are always on that range...

 

Yeah, .025-.028, its not like your gonna feel much of a difference, as long as your close, you're set, I just follow what the HRC pit crew team does on their 420a motors most of the time, since they're running high 8's, low 9's on their forcefed neon, cause I dont have the $$ to dyno tune every single aspect of every little bit of tuning that can be done, where they can.... Must be nice, hehe. I know RRE knows just about nothing about our engines(420a's), as they told me that on the phone... Hell, I ordered plugs from them and they sent me the wrong ones (5's instead of 7's), knowing my engine had a Hahn kit...
