NGK TR6 iridium plugs in a n/a cammed car - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

mike.nite · 08-14-2012, 05:18 PM

A friend installed NGK TR6 (V-POWER) iridium plugs in his 2010 SS L99 with just bolt-ons and told me that the difference is huge. He said that the upgrade was well worth the money.

I do have a 2011 SS with aftermarket heads, cam and bolt-ons. (compression 11:1). No F/I.

Will it be worth to upgrade?

I also have a l99 with cam and bolt ons. I was actually also recommended these last week. I was also told to space the gap in the spark plugs to 40 thousandths (0.040). I am going to put them in in a couple days

Not to be a smart ass!!

But have you're friend define the HUGE difference!!

I can see and expect the difference being in the wallet

waste of money. get some tr5 copper plugs. not kidding. tr6 is too cold anyways.

litle88 · 08-14-2012, 06:42 PM

It's a colder plug, I have them on my 12-1 compression Ls3 stroker in my sig and I would go with the Tr5.

Isn't the rule of thumb 1 step colder for each 100 hp gain??

Higgs Boson · 08-14-2012, 08:02 PM

yes if cylinder pressure is increased as a result. some cams can lower dynamic compression ratio.

op said bolt ons. that doesn't necessitate colder plugs. nitrous or forced induction and some cams depending on valve events.

Okay - With my friends setup (Intake, Headers, Exhaust) the NGK TR6 iridium plugs might seem to be a lil overkill.

But whats with my setup? I have higher compression (11:1), cam and heads. Are they really to cold for my setup?

Higgs Boson · 08-15-2012, 04:58 PM

what cam?

you could try it and see. that cam does not have any positive overlap. just put them in, see how they feel at idle and part throttle. check them once in a whole to see if they start fouling.

im lookin to do something like this aswell , what plugs do u guys recommend im at 470ish rwhp , lg g6x3 cam and boltons. also what plugs do u recommend with same thing but a 100 to 150 shot . will be doing a shot after about a month. but want to see what u guys think in both cases

Higgs Boson · 08-15-2012, 06:18 PM

tr6 for the shot.

I took the TR6 plugs out of my car and put the factory plugs back in and I thought the car idled and ran a bit smoother. I didn't notice any gain or loss in power.

Ted Jannetty was the one who recommended I try this. He said he runs factory plugs with all of his bolt on & cam cars.
