I did a search and didn't find what I was looking for. I have currently have the stock plugs in my car, I want a upgraded set of plugs. I have a predator tune on my car and I think it needs some new ones..Can anyone suggest a best plug?

Thanks

Most people will just run a NGK TR55 on a naturally aspirated engine and a TR6 on a nitrous or blown application. I run the TR55s because I am not spraying...yet. But it is generally accepted that there is not much horsepower variation between plus so i would not worry about any special electrode tips like platinum, etc.

All in all, TR55s are probley what you need.

I use (and have used) TR55s on all my LS1 cars. Very good plug, IMO. I gap them at .055.

TR55s,gapped at .055. Engine runs much smoother than with the stock plugs.

TR55's all the Way! I gap them at .50

SpeedSin

are TR55s already pre-gapped at .055?

tr55's come gapped between .05 or .055, i just checked 'em all before i put them in and the ones that werent quite .055, i opened up untill they were

BTW - Orileys has a large selection of NGK plugs, i would check there first for them. dont go somewhere and let them "cross-referenced" with another brand just because they dont have the ones you need. a few sponsers of this board sell them also.

about three or four of us here have started using Brisk spark plugs with good results. We've noticed an improvement in gas mileage and power. It might be the placebo effect from spending $70 on spark plugs but we seem to be happy with them so far.

there's a couple of pics I took when I got mine.

!70 dollars on sparkplugs mod - no thanks lol i guess the gas mileage would make up for it in the long run (very long run), but i dont have the forsight for that

i could almost get a BMR STB for that much!!

Just ordered my tr55's....I'm still running on stock plugs after 40k miles...no telling what kind of difference I will see!!!

Are the Brisks platinum or copper, as in would they have to be changed as often as NGK TR55s in a stock internal NA set up?
And do they get gapped in any way before install at all?

Neither.. they are silver. We have no results on electrode life yet but the electrode is pretty oversized and should last a good couple of thousand miles.

I have them in my car right now. I saw a write up in GMHTP that did a dyno test using TR-55s and the Brisk plugs. The Brisks did 3 HP over the TR-55s. I figures what the hell, why not. Google it: Brisk GOR LGS-17 it the Part number for our cars.
