Default 2001 PT Sparkplugs Gap NGK at .35!!

Hey All,

I'm getting ready to replace the tired old plugs and wires from my 2001 Non-Turbo P.T. Cruiser.

I have done some of my homework and noted that the plug gap was changed from the old .50 down to .40 on replacement plugs on non-turbo cars.

I bought a set of NGK G-Platinum plugs (3381) and when I went to check the gap, they are all set to .35

I purchased a second set of plugs (Champion Platinum Power 3570) and they are gapped at .40 to .41

Any recommendations as to which plugs to run and why the NGKs would be gapped to tight at .35?

I sure appreciate all the great information from this site and all you experienced Cruiser owners who share what they have learned!

Let me know what I should do!

I believe it was Crewzin that told me that he gapped his Platinum Champoins at 40. Idk about the NGK plugs but i've been seeing them on ebay too and have been wondering about them.

As long as the plugs aren't iridium, you can re-gap them.. just gap them to the recommended spec and you'll be fine. Fixes rough idle issues, and hopefully you replaced the plug wires at the same time. They're complete and utter crap.

I was told that regapping platinum plugs was a no go by the counter people at the auto parts store. They said it would damage the platinum coating.

I'd like to run the NGK's but that .35 gap on the plugs worried me enought to purchase another set of plugs (Champion Platinums) just to make sure if I do the job, it go right.

They're idiots. They advise you not to simply because the average Joe will try to gap them in the traditional fashion by wedging the gaping tool in there, which can damage the plug. Just be careful, but you should definitely regap them.

Guys and gals, let's get this right, okay?

Factory specs (which suck): .050
Platinums (NEVER on Turbo!): .040
Performance on Turbos: .035

Now, it's very easy to test what is the best gap for you. After installing them, gapped at whatever you used, DRIVE THE DAMN THING! After one tank of gas, if you notice no more shudder or stutter, knock or ping, then pull one of two plugs and make sure they are running clean. If they are not clean you may want to open that gap a bit.

If you still experience, or believe you've not corrected, an issue, then go 0.0050 out or in, your call. For instance, if I'm running an NA and only run regular unleaded, I'd probably start at .040 and if I felt I gained nothing, I'd open that gap to .045. If I'm running a turbo, I'd start at .035 and work from there. DO NOT PUT PLATS IN A TURBO! Oh, and yes, don't try gapping them.

Hey Chris, could you get a bigger signature block??? LMAO.

This is a very old thread. There's better more current information to be had. I'm running NKG coppers at 0.043". That appears to be optimum for my car.

I use a very small set of needle nose pliers to gap plugs. Don't pry against the electrode no matter the plug type. If you are having problems with hesitation, consider changing the plug wires if yours are the originals.
