yep thats what i have in there now

 

I'm going to supercharge but i have a long shot before that happens so should i just put the plugs in for now and then when i'm ready to upgrade my intake manifold change to the ngk. Or should i just do it right the first time and go buy the ngk the only thinig is like a siad my dumb *** already has the bosch

 

I'd change to the TR55's now and then just change them for the TR6 when you go with forced induction. My stock platinum plugs were missing half their platinum tips at only 30k miles.

 

cool thanks for the tip bud.

 

Ok heres one for ya i'm getting ready to order a BBK TB for my 5.3 and wanted to know someones insight on getting a TB Spacer from poweraid/airaid when i order. Is the TB SPacer a waist of money ??????

 

01Blackerado... PLEASE don't spend the money on that BBK, gains are minimal for the $400. TB Spacers suck *** too. That's $500 toward the blower...

Also, I'd stick with basic copper plugs. TR55s are what I have in my Z71, the Bosch just aren't good in the performance realm for some reason. Besides the coppers are like $2/plug too.

 

Sweet thanks for the info. So you say no go on the TB and Spacer, should i just go striaght to Cam and Head work after the intake mani upgrade

 

I do believe that they are better than the stock ones, but they didn't seem to like my cam at all. They should be good to go for your truck I would just replace them if you plan on any power adders.

 

I have tr6's im my truck and I love them. Of course i am using NOS so thats why im using them. They are a great plug no complaints here.

 

Yes, TB and spacer are a waste. Stock truck intake will support a good set of ported heads and a healthy cam. You don't need to upgrade that until you're making some SERIOUS power.

Besides, if you went to that FAST intake now with the 90mm plenum you'd be slower as you sit now...flow IS NOT the only thing that contributes to power, velocity does also!
