NGK BKR7E11 Make sure you get them the bkr7e11 are pregapped for stockI buy them in boxes of 10 at 2.25 each so 22.50 a box. I order in the morning and get them at 3 in the afternoon. Always good to have an extra set.

Psi wise I'd run maybe 18 first run 10psi and then slowly up after doing some runs to make sure everything is going smooth.I got a t3/t4 and was running 17-19.

you were running 17 18 on pump gas? or race gas? and where do u buy them? that would be two step?

Ask for NGK plugs for a 2004 Jeep grand cherokee overland (high output engine) edition they come with the BKR7E. Put they come gapped at like .045 I think. When I go to O'Reilly's they can never find the right plug if I ask for BKR7E.

I would also recommend a Kenne Bell Boost-A-Spark. With the BKR7E plugs I run up to 17-18 psi with .06 plug gap. Everything is so much better with the wider gap. Among making more power I get better gas milage to boot. This is on a s14 with internal coil fyi.

What do you guys gap your NGK BKR7E's to?

I was on pump gas. I gap mine down to .030If you want a box let me know. $30 for 10 through paypal. Or just go to our sponsor and see how much they are.... Our sponsor is sparkplugs.com sell them for 2.24 each We get a discount from them usually. Last code I see from them is nicowire....Beleive it's napa that deals with ngk plugs....

.025 for me.............but thats at 17-19 psi on a str8 t3.............

The larger the gap you can run the better off you'll be by the way. So set the GAP for .038 to .040 to start with and only lessen it if you suffer from spark "blow out". The larger the gap the more spark you'll have for a better and more complete burn.
