I know they are ngk's rebranded as ac delco's. What's the ngk part number and the stock gap, also would you guys recommend staying with stock gap? I'm running a trifecta tune at 24psi. I know I've seen the number on here before couldn't find it though.

 

NGK - ILTR5D
AC Delco - 41-108

I think the gap is 0.032. Stock gap is fine.

 

NGK 5476 is the short number.

 

I ordered stock ac delco replacements and put them in my car and its fine. i'm also trifecta tuned.

 

Right on, thanks guys.

 

i was surprised at how hard the delcos were to get. Autozone wont even let you order them from their sight. Advance either. O'reily got them in 1 day for me.
