I looked this stuff up but the conflict on it was horrible. I just want to know with a 4lb pulley .air induction, and single program chip. What plugs are best for the buck !!

I whould also like to no the number of the plugs so i can go get them from a auto parts store tonight .

 

NGK TR-6's are like $1.45 each from advance auto store. I think they are part # 4177. Not 100% sure though because I don't use them anymore.

What plugs are you using now the denso ??

 

IT-24's. they are probably too cold for what you do. In fact you should probably ask the guy who did your chip what plugs and gap he recommends.

 

NGK TR6's will be fine. Part # 4177. I am running them with my 4# lower and 75hp nitrous shot and they are holding up fine!

 

Do yourself a favor and get the Denso's IT 20's for your set up. You didn't spend that much on a L so you could save a little on plugs. The Denso will last and last, idle better and perform.

 

thanks for the replys guys nice pic USA

 

I like the Densos better. I wish they would cost less. I broke the set in the picture when I didn't use enough race gas, I have a set in the truck, and three sets back up. BTW, It only takes me 1/2 hour to 45 minutes to change the plugs now.

 

get tr6's jacob and ill even help you put them in. Thats what i have in my truck. but if you buy my 2lber id run tr5's thats what i did at least. Jamie at manchestor can get either of the NGK's for you. he has them in stock.
