Would it be okay to run these plugs on a n/a motor? I am getting some knock and hope these plugs will help that. I also plan on adding a dry nos setup later so the plugs will already be in. What should I gap these at for n/a use.
Thanks in advance.

Sure, they'll be fine NA. You don't want to change the gap more than .010 and they come gapped at .039. If you're going to install N2O soon then go ahead and gap them at .038-.040.

 

Sorry for all the questions, but will they help my knock problem? Will they hinder performance n/a?
Thanks

They're defineitely a colder plug and be ready for a rougher idle.
If it still knocks, use some octane boost just to see if it takes it away. Use a brand that is reputable and you have heard good things about. Some use dyes that can harm plugs. NOS makes a couple of good ones. This will not, however, be your ultimate fix for detonation.
Have you done any lid or intake mods recently?

 

Thanks for the reply. The only intake mods I have done are, Lid and descreened stock maf. I will try the nos octane boost.

 

You're idle will not be rougher with TR-6 plugs. More likely you'll find it's smoother if you're using stock plugs now.

Use some unleaded racing gas to confirm that the KR you're getting now is indeed real and not false KR.

What do your O2 sensors tell you?

 

z28ss21; sorry for not responding to your email. the reason i run the colder plugs is to reduce engine knock from the ported maf running lean. no NOS in the future for this car.

 

Thanks everyone! I will be ordering some tr6's today.

 

It worked for me...got them from Thunder - best prices I've seen.

FWIW:I tried TR6 @ 45 and lost gas mileage big time about 3 miles per gallon on my bolt on car. Switched back to TR55 @ 57 and got all 3 mpg back plus a little more.

 

i didnt notice any gas loss on mine either... but then again i dont think I ever have a full tank any more.. weight reasons <img src="images/icons/smile.gif" border="0">

but other than idle being a little rougher i ran my best NA with them...

 

I didn't get the car to get good mpg it was nice to 32.8mpg <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" /> on trip <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" /> with the TR55's

With the TR6's the car just <img src="graemlins/gr_chug.gif" border="0" alt="[chug]" /> the fuel down only getting 20-21mpg <img src="graemlins/gr_cry.gif" border="0" alt="[whiner]" /> in my normal driving instead of the average 24mpg.

 

Mmmm, I have TR6's at .45 and get 19-25 mpg with headers, 3" o/r Y, no cat-back(just over the axle), lid, Maf ends, MAFT... In an A4 and stop and go traffic most of the time.

 

I was hoping mine wasn't the only one idling rougher. I went from Autolite 103 to these.

 

Hmmm...I wonder why some have a rougher idle with them and others have a smoother idle? <img src="images/icons/confused.gif" border="0">

I went from stock (good idle) to Autolite 103s (rough idle) to TR-6s (great idle.) My TR-6s were gapped at .037.

 

My car idled and ran like crap on the Autolite 103's. I left them in a week until the TR6's came in.

 

I had a lot smoother ride with the tr-6's.

 

TR6's gapped at .040 and I've probably checked my wires and plugs three times , just to make sure they're all tight. LOL
4 months with heads and cam and you would think I would be used to it, but sometimes that idle seems off.
I guess burning the CPS harness twice would make me a little leary as well.
FWIW, we just changed my buddy's plugs from 103's to TR55's and his idle is great and he ran new best numbers on the spray. He's all bolt-on though.

I'm still going with the tr6's, becuase of my knock and the car idels rough anyways. Thanks for all the help guys!

2K2 LS1, what are your plugs gapped at? <img src="images/icons/smile.gif" border="0">
