[archenemy236]

Thank you everyone for the help, I regapped them and its running perfectly!

I was getting big time stutter at 5.5k and up. Now she goes all the way up and i gotta be carefull cause the rev limiter comes awfully quick now! I honestly was suprised at the difference it made!

Going from 1.1mm to 0.8mm on stock boost with restrictor still in made a world of difference to me

Were you getting stutter with restrictor?

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

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

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

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

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 :\

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?

gap???

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!

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

They are copper NGK V-powers.

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