Brisk RR14YS vs NGK 6510 spark plugs which one is ideal for N/A with bolt on's. Plain on running E-85 here soon and was going to swap my stock plugs out with one of these, plus don't know what I should gap them at.

n/a car, stock gap

either plug is great, but those are 1 heat range colder, which, n/a isn't needed.

1 colder would be for supercharged setups

unless your do for a plug change, leave whats in in, no need to spend money on nothing

I just went FI after E85 N/A for 6500 miles. The stock plugs I took out looked fantastic! Why are you wanting to go to a colder plug?

Why, why not, either way i'm swapping them out just wanted to know what others are running. Just want to run one step colder plugs. Perhaps i might run a wet shot sooner then later. What is the stock gap? .048-.052.

reason he is saying that, is colder plugs, if not needed, can actually cost you power

.050 ???? I thought I read where people were gapping the stock plugs at .044 or .045 NA for some reason? I have a set of 6510's that I was going to install with cat deletes, a JLT CAI, LU47's and a flex tune (but E85 most all the time). but no reason to until I put nitrous or a blower on it.

gap as wide as you can without blowout will get you the most power

Ok... so .050 is what you would gap a NA set up at? On a stock heat range plug..
