What Plugs And Wires To Buy?

[cybertech]

I have just purchased a 2003 thoe with the 5300 engine and I would like to change the plugs and wires. I was wondering if you guys would have any suggestions as to what kinds to use and what to stay away from. Thanks

oem wires all the way. either that or a really really good brand like taylor or msd - but some have had problems with them.

 

for plugs either the stock delco plugs or ngk tr55ix's, and to that end I believe I still have a full set of brand new ones $40 to your door.

I love ngk plugs and they would be my first choice. But I wasn't sure what experiences you guys have had on here with them.

Stay away from the platinum and iridium plugs and go w/ the standard copper core ones for $2.00 each. As far as wires...aftermarket wires are far superior than the stock GM wires and probably cheaper. I've got MSD wires on my truck and have experienced no problems whatsoever.

The stock plugs should be iridium. I would not use platinum or copper, stick with the iridiums. I have used the stock AC Delco iridiums and now I am running the NGK Iridiums. I like them both, but prefer the NGKs. Mercruiser (GM) boat engines come stock with ACs, but Mercruiser recommends NGKs as replacement plugs.

 

I have used the MSD wires, but now I'm using the Taylor Thundervolts 50s. My preference is the Taylor wires and NGK plugs.

I was told by a reputable speed shop that tunes hi performance vehicles for a living that iridium and platinum plugs are crap. Pay $60 for a set of plugs but these guys say run copper.

So whats wrong with Platinum's? Do they ruin gas mileage? Low life span? Someone said so? Im failing to see why iridium and platinum plugs are crap.

Call the guys at Lonestar Performance in Dallas, TX and they'll tell you why. I discovered this on a recent visit there when I towed a friends Saleen Mustang to them to tune. First thing they did was take the platinum plugs out of that Stang and throw them in the trash. They installed 2 dollar copper core plugs and told us that the others were crappola. This place uses a dyno to tune vehicles on a daily basis and they are usually booked solid. I'm thinking if anyone knows what plugs to use it would be guys that do that sort of work for a living. I've tried the iridiums in my truck personally and I don't care for the way they idle not to mention they are just too expensive. To each their own, if you want to use iridium or platinum plugs go for it! Like the old saying goes, "opinions are like a**holes, everyone has one".

I got the ngk iridiums and I ordered a stock set of wires from teh dealer. But the plugs are still in the packages so I can still switch if need be.

That's your call man....for me nothing more than 2 dollar copper core are going in my 5.3L.

I run copper core NGK TR55's with platinum tips, I think they were around $2.40 each. I was just curious

 

Iridiums do seem controversial, some people swear by them, some people swear against them.

I guess i'm going to have to do some research on the net about the different metals and what not.

[cybertech]

What about GM wires is there any problems with them?

Here you go....give them a call and ask the experts and no offense but TR55's are not platinum, they're basic plugs...just what the guys say to use.
