Wondering if u guys had thoughts on this....I'm currentely running the RB ones, but the Mazda shop that i take my car to said that when he uses NGK he has no problems, but when using other companys, he says that brake faster than the NGK's. Which one should i with ?

 

Ummm...what is "ones", and "other companies" what?
What the hell are you talking about?

plugs? RB sells ngk plugs...

 

Yea what he said... ^

The "ones" thats RB sells are the same as the "ones" that ngk sells. RB just has more heat ranges listed of these "ones" than you would get if you went to an auto store to get these "ones". Teh more powa your making the color you want the plug to be to prevent detonation... like this = BIG TURBO, LOTTA BOOST= COLD "ONES". "Ones" with higher # rating are colder, the lower the # the hotter. k?
