plugs NGK'S or Champions?

[JsMidnightblue]

I have been reading that most people go with the Champion double platinum's but I have also noticed that there are a few that use the NGK iridium's, I would like to hear from both sides about the pro's and con's (if any) of these 2 plugs and if you really need to go bigger than 8mm. with your plug wires and are there any out there that are less expensive than most. I am still running stock plugs and wires and am trying to narrow down my choices.

Hey JS.

I just changed my plugs and wire last week. Got the Champion Double Platinums from my local Advance Auto for $4.48 a piece. Picked up a set of Crane FireWires for around $50 (8.5mm).

Car runs nice and smooth, seems to have better pick up and smoother acceleration. Haven't driven it much since doing that, but so far I'm please with the results.

JS-
You don't say, but I assume your PT isn't turbo. On my '02, I went the same as Wyzard - Champion double platinum & Cranes. I had a "miss" or stumble that completely went away.
I got the plugs at NAPA, wires from RaceAndStreet.
I don't think bigger wires are needed, just ones that are better than stock - they don't last. The Cranes do.

Agreed, for a non turbo the double plats will work fine and if you can find them cheap so will the MOPAR high performance wire set for $40. What yu really need is not bigger but higher quality plug wires.

You can get NGK's and wires for about $70 from NGK, or sparkplugs.com, I have the Iridiums, and love em.

Yeah, I just picked up a set of NGK Iridium IX's & a 9mm wire set for $69 from sparkplugs.com. I installed them in my '03 GT this past week and have been very satisfied.

My car now idles and runs smooth did yours?? I was really suprprised how much of a difference they made as I was not unhappy with the stock condition.

It was still running pretty good before the plug change ... just a some occasional unevenness on strong acceleration. As smooth as new now, but I haven't had a chance to see the long term effect on milage. No unevenness even at WOT.

The champions I pulled still seemed in pretty good shape - all had a .055 gap & the insulators seemed the right color/condition (though the electrodes looked a little blurred around the edges). The NGK's were dead on the listed gap of .052 right out of the box.

Hopefully the silicon grease in the boots will make the next change easier. Getting the stock boots off was a bit of a pain (literally - I lost some skin on a couple when they broke loose).
