BKR7E Spark plugs RB26DETT

[archenemy236]

Can I run BKR7E spark plugs in a RB26DETT? I'm running 14psi intakes, and exhaust done, plus a Tomei tune.

That's what I run in mine, similar boost with a Blitz tune, works great for me. even better after I upgraded to Yellowjacket coils.

Just make sure they're gapped at .8mm

Awesome thanks alot!

Who makes these? I would consider picking up a set for my rb26 if they were good

[archenemy236]

They are copper NGK V-powers.

Did you guys ever heard of NGK R5671A-10, this are super cold spark plugs, i am running them on my Daily driven turbo Altima for like 50k now and love them! Here is the pic!

Just put in the BKR7E, and now im having a problem under full boost in 1st 2nd and 3rd it sputters and then i let off gas and it backfires, anyone know why it would be doing this?

I've run both these and BRK7Es with no issues. They are both popular in the turbo BMW world.

gap???

[archenemy236]

I have them at the stock gap for the plugs at .8MM, I didn't actually check them tho because I didn't have a gapper and I trusted the spec :\

[Daryl @ RightDrive]

Are those R5671A-10 a heat range 10?? If so that's too cold!

[archenemy236]

Just check NGKs site and they are showing up as "035" (0.9mm) Gap"

I use the napa 4091 plugs. Copper V-power, still good at 600whp as per other forums.

[archenemy236]

Is .1MM actually going to cause it to sputter under 14PSI?
