Just wondering whats the best plugs to run with about 15psi to 20psi

 

You can get away with 7's, but some will suggest 8's. I think 7's should be fine, but without first hand experience, I'll let someone else fully answer the question. There shouldn't be any way you'd be in need of anything colder than 8's, though.

 

ngk 3330's...just change them out kinda often(like every oil change) cause they tend to get sketchy when they are ran for awhile. but they are only like 1.25ish a plug so its no biggy.

 

where do you guys buy your colder plugs?

 

for 15-20 psi try running ngk part number 1095 which is bcp7e-11
for higher boost run ngk part number 5820

I get all my NGK's at Advance Auto Parts. If they don't have them, they can get them the next day for you. Like $1.80 a plug too.

 

the part numbers for the 7s are 4091. and for the 8s is 4554.

 

I know this might sound stupid but these 7's and 8's you talk about are they ngk

 

yes

 

damn, those are some cheap plugs. The guys around here have them for 2.40 or something.

 

thanks for the help

 

i would run the ngk bkr7. i think it is a beeter plug for a turbo app.

 

thanks for the info

Just for future reference, do not get the '-11' plugs. They come with a stock gap of .044. Get the regular BCPR7ES's which come with a .032-.034 gap. They are the exact same as the -11's but the gap is different, which means less stress on the actual tip when gapping. The BCPR7ES part number is 3330.

I was under the impression this was a better plug too until I compared it to the bcpr7es. If you look at the 2 side by side you will see the insulator of the BKR is actually longer which sits further inside the combustion chamber. You know what that means... it is exposed to higher combustion chambers which can lead to either pre-ignition and/or detonation.

Just a little more FYI for you guys.
