NGK is tough to beat, I run them in all of my vehicles. GM to Mopar. Be careful if you order online, there’s been some knock off NGK’s to surface on Amazon and eBay.

I've ordered mine off of Amazon is there any way to tell if you got the real deal or a knock off.

What spark plugs do yall run or suggest to run on a 09-15 cts-v?
What are your mods? What are you seeing for boost pressure?

I went with the 7 range Densos and am modded. So far so good. I pulled the stock plugs on the car with less than 30k miles and the tips were gone on 7 of 8. Should have done them way sooner and grabbed a pic but it was like this. Any new plug is better than what's in there now!

NGK BR7EF (3346) gap .028
Brisk Silver racing GR14YS (non-projected) for E85 .028-.032 gap
TR7IX .030 gap

My personal choice [email protected]
No issues on either ones of these three.
For wires, Accel Extreme 9000 ceramic 9004C work great with LTHs.

NGK br8es plugs might be indicated for more "wild" engine setups. I found the 7 series seems to run a little hot.

Br8es is what I run in my 2 stroke quad. Interesting to hear this is run in LS set ups.

I just found my new career path. Buy 6 NGKs at O'Reillys, buy 6 NGKs off Amazon, return to Amazon plugs to O'Reillys. 😄😄
