Ngk -11?

[Pimpin Dsmstyle]

I asked for the bp.... ( i forgot the rest) but the ones we are SUPPOSED to run in the dsms. I put them in and all of that. For some reason, I think there was a dash 11 at the end. Now I am having spark issues. Could anyone give me some insite on this? Thanks.

BPR7ES, unless your car is totaly stock you should run BPR6ES.

Well if you have the wrong plugs, that's probably it....

They do make a BPR11ES I believe, and if you have them in your car it will most likely run like shit. I usually gauge it by boost with my cars, if you are running more than 16lbs then run the BPR7ES and anything under that run the BPR6ES. The BPR6ES are less prone to fouling as well.

No, he got some BPR6ES-11's. Did you check the gap before you put them in? The -11 just means the stock gap. I believe the -11's are .045" gap or something like that. They will need to be re-gapped to .028" or so. If you are running them stock the gap is way too big and will cause your spark issue.

JET is right, they are just a lot wider gap. Bring 'em down to .030" and you're good to go.

The plugs with -11 on the end mean a 1.1mm gap. You have to gap them way down to use them, next time just try to get the ones without -11 on the end, so that you don't have to bend the ground strap over so much.

i just bought the right ones. The fuckers at napa gave me the -11 instead of the regular ones and i dont have a gapper so i couldnt take car of it right away. The car is still missing all over. Mostly in the boost. I know the plug gap is part of it, but it was doing it with the other plugs ( good ones i had gapped at QPR and installed 100% properly). I guess it could be something fuel.. ideas would be cool.
