Heard twp different things

[bcjjones]

I have read on my car, 1993 eclipse non turbo 2.0, that the spark plug gap is. 044
But the guy at the auto parts store says its .026 which is a huge difference.

Not the best place to get advice so I decided to ask y'all experts. Which is correct? Also my car has been running a little rich so could I possible close up the gap a couple thousands to help that or is that a bad idea?

pretty sure i ran my n/t around .40ish

 

[Bud92gsx]

The people at the auto parts store always say .032 on a turbo motor..Most of the people around here run .030 or less..

Now on the n/t motors you need a bigger gap..I would just go .040 and call it a day..

 

[Bud92gsx]

30 but I have the turbo

See .030 is pretty good..I run .028 I think..

On a n/t I would just buy the plugs and throw them in there.

 

[Bud92gsx]

^ ...Just throw them in there...That's got me cracking up..

ALLDATA specifies .039-.043 as a gap for a non turbo 4g63.

 

[Bud92gsx]

Just curious..What does alldata show for gap on the the turbo 4g63?

 

[95TalonOwner]

ALLDATA specifies gap of .028-.031 for a turbo 4g63.

 

[AK Thunder]

If I'm not mistaken, your owners manual will tell you what the proper gap is.

 

[Bud92gsx]

ALLDATA specifies gap of .028-.031 for a turbo 4g63.

It does..Well the parts stores really need alldata then..My car ran much better on smaller than the .032 gap they told me to do years ago..

The bigger gap is correct for the NT 4G63.

I just get the platinum +4's. They are gapless and their beast. I saw my MPG go up a couple two. I was surprised it went up that much.

OMFG, do not get these, stick with the tried and true NGK BPR6ES's. Bosch is garbage in these cars.

 

[Bud92gsx]

On a n/t I thought you could run platinums..

 

[FearlessNick]

Well my parts store didn't have NGK's. So I got the platinums for the mean time while I'm waiting to accumulate some money. And I talked to my dad about it and he said their fine for the 420. Because i heard someone ask the same question before I bought them.

I don't hear ping or anything with them. And my MPG's went up. So I'm satisfied with my buy.

The parts stores never have the cool stuff you need.You have to order all the cool stuff..

 

[FearlessNick]

FearlessNick, you probably have good luck with plantinums because you have the 420a. For 4G63s, use copper NGKs.
