what brand plugs do you guys use?

[Sinister95Z]

For N/A use : NGK TR55
Personally I use a NGK TR6 due to the spray.

[Brandon]

never heard of them. ill stick with my ngk tr-55 ix's

[bad93ta]

NGK TR55's also

[Shaggy67RS]

NGK TR55's also

Yep, same here. Always heard good things about them. They're pretty much THE recommended plug for N/A LT1s, from what I have seen.

[Tyler Wheat]

I was using the TR55s until I put the nitrous on my car. Now they're TR6s. Those plugs in the picture are more than likely not worth the money. Reminds me of the Bosch Platinum 4s (or whatever they were) that people were so crazy about.

[Z28pr0jekt]

MANY people found problems with those plugs (cracking etc..) if you do a google search you will find multiple problems with them

[fuels94]

Since everyone so far use NGK's i'll be the different one and use Autolite 104. A decent plug for spary and you can't be the price.

[YZF]

TR55 FTW!

[Boostin' Ain't Easy]

TR6 because of boost.

[Brandon]

Reminds me of the Bosch Platinum 4s (or whatever they were) that people were so crazy about.IDK why anybody would want those. How do you even gap them?

[YZF]

IDK why anybody would want those. How do you even gap them?

I love when people tell me they put pre-gapped plugs in their car.

I kind of feel bad for 'em.

[Hot94Z28]

I run NGK TR-55.

[Fixxer99TA]

NGK TR55 or TR6 .... AC Delco for stock.... You dont need anything else :D

[Malice]

I wanted to try the E3 plugs just to see if they were a gimmic or not.

I was gonna install them when I did my header install, but I forgot. I'm not gonna try to install new plugs underneath edelbrock headers unless I absolutley have to.

[Biggin'89]

I run the autolite 104's in mine, thats what Lloyd E. recommended.

[LT1_Fireman]

I ran tr55 in mine n/a ,tr6's on lower boost,now I'm up to ngk r8's due to boost

[Fastbird]

E3 = Gimmick plug. So does Bosch Plat +2, +3, and +4. Waste of money.

TR55's for N/A cars, TR6 for your typical Spray or Boosted cars (or equilavent from Autolite, they've got good plugs too).

[Toronto_LT1]

thanks for the reply guys

did a quick search, E3 plugs = garbage!

TR 55 users, platinum or iridium tip ? what do you guy's run?
also what is the part #?

[Alex94TAGT]

Since this forum is new, I guess we need to get the subjective "which oil/filter/spark plug is best" stuff out of the way so we can tell people to run a search. ;)

+1

I've used Autolite in my LT1 for the past 6 years or so -- I really like them. They're cheap, you don't have to worry about platinum pucks falling off and opening up the gap, nor do you have those stupid screw-on wire terminals which can loosen up. I end up replacing plugs once a year anyway just for shits and giggles, but they seem to run really well.

Everyone recommends the NGK TR55's, but my car didn't seem to like them back in the day. Maybe I got a faulty set. Only tried them once.

Exactly. I don't understand what people are thinking. There's only going to be one spark even if there are four electrodes. The extra electrodes are only serving to shield the spark from the fuel. I guess people think it's equivalent to putting four spark plugs in there?

[bad93ta]

TR 55 users, platinum or iridium tip ? what do you guy's run?

I just use the platinum
NGK Part #3951

Iridium plugs are 6 times harder, 8 times stronger and have a higher melting point than platinum. thus good for nitrous...

[Green96Z]

NGK TR55s here as well. AC Delco Platinum is a good plug too. I wouldn't put any plug in my car I couldn't gap.

[jarretthise]

never heard of these plugs...why do ppl use the ngk?? ac delco is way better in my opinion

[James Montigny]

TR55s here as well.

[Brandon]

what is so much better about ac delco?

[Toronto_LT1]

thanks for the reply,guys.
i think i'm going with TR 55's.

[SoulReaver]

I ran those for about 6 months before they shitted out. I'm running stock ac delco plugs now, but want to make the switch the the NGK's.

[Milk Man]

i just picked up a set of tr55's for my new motor. kinda thinking about the tr6's now bc i will be sprayin it. hopefully autozone has them lol, returns ftw

[captainofiron]

I know this is a REALLY old thread

But I wonder what people's opinion is about these now

Supposedly there is dyno numbers out there proving these to be a better plug

They showed on Hot Rod TV them testing these in an engine dyno

Of course I am VERY sceptical

[SexyTransAm]

NGK BF6 here for spray

[Spartan7]

I ran Autolite 104's in my H/C Camaro, and I'll probably go with AC Delco Platinums for anything else. I just can't see justifying spending $7 a plug for iridiums.

[razor02097]

I have AC delcos right now. I don't see much advantage with the E3 plugs when I really looked at them.

[CamaroGirl]

yea i've been told the older the engine is, the less it will get along with a plug like this. these newer cars need platinum and iridiums so they can run efficiently. older engines, not so much.
the e3 plugs, at $15 per, are not worth it imo.
go with what works, plats, or v grooves.
especially if they're a bitch to change.

[96LT1355Z28]

I used TR55's for awhile but switched to Autolite 104's recently as recommended by LE and Ed Wright. Both are cheap and work fine. To me the E3 is another gimmick plug like the Bosh +4, and the old Splitfires!

[MeenZ28]

I think the real question is - does anyone have anything good to say about these pulgs?

[SexyTransAm]

none what so ever! lol

Hotrod TV is also PAID by these companies that their products are shown. So if someone sponsors you, you better have good things to say about them. They are a gimmick plain and simple.

[huntr1117]

Another vote for the TR55s

Yea that was exactly Why I am skeptical, BUT I had the same point of view with the K&N's and that turned out to be a good thing

so not always are gimmicks equivalent to junk, I was just looking for some empirical data, aka independent dyno numbers

I would like to see the "emperical data" as well. Seems there is a LOT of opinion floating around here. For those who run NGK TR55's and are complaining the Platinum +2/3/4 plugs (or even the E3 plugs for that matter) shroud the electrode, I wonder how many of them index their plugs? If you don't, you are shrouded as well. Definitely not saying there is anything wrong with the NGK's, just saying opinions are like butt holes: everybody has one and they all stink. Give me some cold hard data.

So do the farts I cut, but you don't see me bragging about them (they speak for themselves :laugh: ).
