I was going to buy a set of stock delco plugs to replace the ones that are currently in the car unless there is a better plug out there. I found on a search a lot of people using NGK TR55's (i think) and I see some people useing D3's

what do you reccomend?

 

If you are just bolt-on's etc... TR55's. If you are anything else like internals and/or boost...try tr6's. you can get either of them for only like 2 bucks a plug at your parts store

 

i run ngk tr55's.switching to br6's when i install the nitrous kit

 

TR 55's and if your doing FI or Nitrous TR6's. I have tried every plug out there and I can say with an amount of certainty, that the NGK product is the best out there for the LSx base engine.

 

TR55 IX, I like the iridium plugs. If your car runs good and is tuned properly, the should last a long time.

 

Like they said, make sure you choose the right plug for your setup: N/A (TR55) or blown\tubbed (TR6). I also like the IX (iridium) plugs, because they have a thin wire contact that allows better flame propagation.

 

Thats not good advice.tr6's are projected tip plugs and should not be used with nitrous.A non projected tip like the BR series plugs are what should be used on the jug

 

cars stock, I read about E3 plugs, is that a gimmik?

I have also wondered about the E3s.

 

Here is the thread on what sleekbeak is talking about

Is this the plug to buy?

This is what i've been told by guys i know with LS engines running juice. The BR6s are great with nitrous; but they aren't so great when you're driving around and NOT spraying... That's why alot of people recommend the TR6s because they're great driving around without juice, but they handle spray really well... just not that many runs. So you end up having to change them out so often.

So it's just a matter of what you plan on doing. Driving alot with the "occasional" spray? TR6s will be ok, just check/change them periodically. Driving around only looking to spray everyone you see in sight? BR6s is what you need.

If non of this applies to you, you are just bolt on/cam etc, TR55 or TR56s should be fine. I have TR56s on my cammed LS1; runs great, no ill effects, plugs look good after giving it hell for 3 months. But i do want to see how the TR55 iridiums fare; several people i know seem to prefer them

 

Like most have said, TR55's will do the trick!

 

Yup thats what I'm running used to run those tr55s with a 75 shot on my old gt and never had a problem.

Sorry, shouldn't have thrown tubbed in there; thanks for the correction...

 

Here is a platinum TR55...

They are less than 1/2 the price of Iridiums.

 

I don't know because right now out of the 300+ members 10% of the cars that are part of our car club run juice to include myself. We are all using tr6's and to date no issues. But then again I could be wrong.

 

no problem
i hope i didnt come off as a smart ***.Alot of people run tr6's and have no problems.its just a good measure of caution to run a non projected tip plug with spray.That link that was posted is a goldmine of info.read it.you will be glad you did.I know i sure was



And OP, like it was already stated if your not spraying then dont worry about any of this and go get yourself some TR55's.

 

what is the recommended gap setting for these plugs? Motor will be a carbed ls engine with cam and bolt ons.
