I have a d-series turboed, running 15psi, with stock plugs set between .30-.35. I was thinking about going a heat rating to a 6 or 5, but not sure. What do you have? And how does it run?

 

NGX-BKR7E

.28 gap

platinum.

 

I have 6E's at 0.038", 14b @ 10 psi. For 15psi I would go with some 7's as platinum stated.

 

running bkr7e's myself and gapped to .25

 

damn, I gapped them at 30-35, but Its still a little ~~~~ doesnt seen right.

By the way, Running 15psi on a Td05, built bottom end, stock top half on a d16z6. DSM Injectors, FPR. And Uberdata <-- The car came to me with this problem, but I will figure it out, it may be a start of a scorched valve, being stock head...

Same plug here gapped @.032

 

running 15-20 psi....

bkr7e-11s's (i think)

i have them gapped to .28 also, and i havent seen any issues with it.

 

i run 10-11 psi on a 14B

NGK BKR7E-11's gapped at 25

 

BKR7E gapped at .28/.30 tried both cant really tell a difference...

stock d16y8, t3 .60ar/.48 10 psi

 

Well the biggest gap you can run is obviously best I have to .028 or I developed a miosfire... Definitely get a step colder lug in there you could be getting preignition.

 

I have the plugs gapped at .030-.035 on Stock NGK Plug which are a heat rate 7.
The car ran smooth for a while and now its develope a flu. When you rev to about 1.5 in gear it bogs, and will bog again around 3k. Havent done a compression test yet, will do probably tomm. The bottom end was built but I think It my be a valve letting in some unwanted air..

 

Try a smaller gap 0.28 you boosting at 3k?

 

I will try that, and I will get some new plugs just for insurance, there about 3month old too
