Can't find searching. Would this be the correct spark plug for a mild bolt-on tuned z06? A Brisk RR14YS would be one step colder than stock correct?

I just put a set in myself, everyone I asked said it was the set to have. Will take to the track next weekend, know more then

I run the BRI-RR12S in mine, it is a non-projected plug. They also make a BRI-RR14S which is hotter.

I also had the BRI-RR12S with me racing engine LT4 installed
I removed the candles because the candles are too cold and the engine stuttered a lot.

I have now reinstalled original to test.
The engine is running perfectly

In the summer when the engine gets extremely hot eventually

I'm curious about your experiences

I have not had a problem but i do live in South Florida which is warm almost all year round. I run an E60 mix for fuel with meth injection to supplement the fuel system.

My car is with Jeremy Formato (Fasterproms) right now getting the goods put on the car and if I'm not mistaken, he used the 12's as well.
But I too live in FL and will run 100% E85 and have meth injection, etc...

Surely there are more members that can help and chime in on this..

The obvious best plug IMO is the stock Iridium. Why worry about the plug? The heat range would first to me? If I was worried about them. Someone enlighten me!

What gap are you guys running on the 14s?

rflow306

I run them at .28, I have heard of people having issues with them at .32 and above.

Don't mean to light up an old thread but need some help guys. Today I had the car dyno'd and threw a misfire code on the way home P0301 (misfire bank 1). I swapped the wires and got P0300 (random). IR gun showed Bank 1 running about 30-40 degrees cooler on the header pipe. I also threw a "Service Stabilitrak" warning which seems to be tied to the misfire. My thoughts it has be the wires and plugs. Pulled plug #1 and seemed to have a decent amount of oil on it (yes, I'm worried).. but I need to get new plugs and wires and wondering if you guys are having success with these 1-step colder plugs or should I run something different? I'm a Callaway with a 9% overdrive pulley, Kooks headers, Intake and Methanol. Dyno'd at the wheels today at 810rwhp.

Should I run the RR14YS or something different? If the RR14YS what should I gap it at?

I am using NGK LTR7IX-11 plugs gapped at .032

That’s what I am running in my ZR1

Thanks guys. After a little more research it looks like the RR12S is the plug within the heat range of 8. I would really like to stick with that heat range and not drop down to the 7 of the NGK LTR71x-11 plug no?

Nick001

Here is a list with Racing spark plugs to compare
The NGK 7 is very good, safe for the road

For races with very high combustion temperature
I would choose the 8

Meanwhile I drive the Denso ITV 24
The whole season without problems

SteenC7Z

Thanks Nick! That's actually what I just pulled and I think Callaway installs the ITV24 with their supercharger upgrade. The Brisk RR12S are in the same heat range and got alot of raving reviews on the forum. Just trying to figure out what to gap them at now? .025?

Nick001

With the Brisk spark plugs, I had many problems with misfiring P0300

For this reason I have changed

Since I have installed denso, I have a perfect ignition
The distance with 0.025 I have that too

SteenC7Z

dang! Ok.. maybe I’ll cancel the order now and order the ITV24s lol!!

What does Callaway say?
