Here is the NGK-6509 / LTR6IX-11 that I pulled from the car. Looks light carbon fouling, maybe too cold of a plug.

I use NGK TR6IX/3689 & they look about like that, but light load driving will make them look fouled. When I make a drag pass then they look perfect. Also I noticed the plugs you are using have a 1.00" reach, which is to long. Mine are the factory reach of .708"

The LTR6IX has a 1.00 reach
The TR6IX has a .709 reach
Stock ACDELCO 41-114 has a reach of .98

Yours is far less of a reach than factory, and I don’t drive very light.

I just looked it up the 41-114 has a reach of .708 is what Summit Racing advertises & yes others say .984
Oh well I like the one's I'm using & don't like them protruding into the chamber if any & I like NGK way better than ACDelco

Interesting, I checked your source and you’re correct on that for summit.

Although I checked JEGs, oreillys, advanced auto, and something else and it says .98...hmmm I dunno man.

If mine don't look as good as 3rd row #2 I replace them.
