I need a plug that has a heat range 1-2 ranges colder then stock, and
is a non-projected tip.
I've run the AR472's, but I feel their too cold for what I need.
Just need something that is a little more forgiving while off the bottle.

 

ngk tr6 gaped at .035 i have had a set of those in my cars for around 10k miles. my idle is close to stock. i get a little surge but nothing that affects drivability.

 

That is a projected tip plug.
I need something in that heat range that's non-projected.

 

I had good luck with the AR94s. I have AR93s in the car right now and I am daily driving it. sitting out side the Office right now and it was 44 Degree's when I left for work this morning.

Maybe they will work for you ?

 

could try NGK BR7EF (stock number 3346)..... two steps colder than stock. we have run them pretty successfully with up to 250 shots
