So will a different plug better suit the running charicteristics of a cam'd motor over the OEM plugs? For those that don't know, I'll be running a 6.0L with the TR 224 114LSA cam, what will be the best plug for that set up? Is there a better plug than the Delco's for a cam'd motor?

 

I've always like NGKs. I ran the TR55's with my old LS1 w/ TR220 cam. I'm now running the TR6 (one step colder plug) because of the higher compression LQ9 11.5:1

 

do the TR55's suit a cam'd motor better than the Delco stockers?

 

Delco and NGk are basically the same company.. or one owns the other IIRC..
but you can probably get TR55s cheaper.
Im goin with TR6s before i spray..

but im not sure if you will see a difference with just plugs.. but i dont know...

 

can I get the NGK's at the local parts store? and will they show them as an application for my rig?

 

I'm doing zex for turbo's, but they also have zex for high performance and I like them so far. Check em out.

 

yea just tell them what you have and tell them you want NGKs and TR55 should show up..
or just go in there and tell them you want some NGK TR55s...

 

stock replacement plugs will be fine. i'm still running the factory ones with 43k mi. with no problems

 

your numbers speak for themselves...I'll stick with the stockers

 

yep. is allen doing your tune? if so, he suggested that the stock plugs were fine for my application.
