Spark Plugs?

**CWW17** · 07-02-2007, 07:56 PM

I'm about ready to put some longtubes in and was wondering what spark plugs I should buy... Seeing as how I'll have a little better access to them with the headers off... Thanks!

NGK TR6's for Nitrous / FI setup
NGK TR55's for N/A setup.

Iridium

Then you won't have to change them every 12K

At about 15,000 miles on my TA I installed the ngk TR55 plugs because just about everyone on the board uses them.I changed my plugs last week with the car having 35,000, but I went with the AC41985 plugs, which is a stock plug.I have found that it idles better to me and I want have to change them as often.The TR55 may be better but I just can't deal with the content plug changing. I want be changing them again until I get about 75,000 miles on it.The car sits running and you can't even tell it unless you tap on the gas. I am sold on the stock plugs.

+1

Although there is something to say for stock ACDelco replacement plugs if a stock plug fits your application.

I like the NGKs. I'm currently using TR6s at .038 gap for the 383/spray...

havent change the plugs yet on a f body only on my other cars. is it true that you have to do the # 8 plug from under the car.

explain the install if you can. i have 35,000 miles soo far and getting ready for NX soo i know TR6

make sure you buy some anti - sieze for the threds of the plugs. and some sealer grease for the boots and top ends. only like 4.00 if you buy the small one time packs but great for the later use and utillitiy

I have found out that taking the coil packs off makes everything much easier. Although it might take 30 minutes longer but it will save your hands.

thanks everybody for the info!

It is ALL motor combo?

**CWW17** · 07-06-2007, 01:45 PM

yeah... i dont have any power adders

**va2001ss** · 07-07-2007, 08:19 AM

NGK TR55 this time. Last change I used the TR6's, I liked those better being a cooler plug, the the TR6's seemed to prevent knock a little better.

**LS2Tuner** · 07-07-2007, 10:33 AM

I would run the A/C Delco Rapid Fire #12's for a ALL motor combo.

**CWW17** · 07-07-2007, 12:03 PM

so you would recommend those over the NGK TR55 IX's?

**LS2Tuner** · 07-07-2007, 01:55 PM

Yes I do. I don't really care for the NGK's myself. If you really want a irdium plug which some do than I put the Denso in my customers and that part # is 5325.
