Don't quote me on the double platinum thing, might be laser platinum- not sure. But those are the guys you want

 

I use ngk coppers(probably v-power, but I forget) 2 steps colder 6psi wastegate. 2003 de

Stock iridium(no step colder) worked fine until I advanced my timing and I started getting misfires.

 

Stock ones are not iridium for the DE engine

 

Ohhh gotcha. Autozone tells everyone iridium's come stock.

What is it plats?

 

I use NGK LFR6A.

 

Yeah the ngk plfr5a-11 laser platinum are oem and imo they're great for na. I run the plfr6a-11 at 470 wheel no issues. Most everyone does

 

Ok..So the plfr6a-11NGK will be best for my F/I set up.

Laser plats..correct? Tks bros

 

Yes correct, good luck you'll like em
