About spark plug...

[AUSCE]

Do you know the calibration from spark plug to the ECOtec 1.6L?...

Or how can i obtayn the FSM?...

I smell gas in the exhaust, i thing the mix is very rich, and supost the calibration, mabe is wrong, when i replace the spark plugs for the iridium spark plug, i meassure the stock plugs end calibrate, but still smell...

The first time I install it with the precalibrated -011 I think is .44, an then i adjust like stock i think is .43....

i think you want spark plug gap but not sure so here it is.

Yes it is!!!, thanks, y calibrate with 0.043 inch, but smell a little a gas...

the spark plug came with .044 an smell more...

thanks a lot!...

I'm not sure if the thinness of the tip affect the size of the calibration, since the original tip is thicker and thinner iridium ..

the pics isn´t good...





the replace sparkplug...

I have 88k on my 07 and they have never been replaced..would I see a small gain replacing them w better plugs or should I just wait for a while?

s a big mistake, spark plugs are not eternal, wear out ...

of copper, are changed every 6000 miles ....
the Iridium every 25.000 miles if you use nitro or turbo, you should change it to half the use by abrasion ....
and platinum are changed every 60,000 miles or so ....

any material or plug is eternal, especially if subjected to combustion in an engine pressure are extreme conditions, see how mine are the stock at that time had only 6,000 miles, that wear causes a spark of poor quality ...

Change them and take a picture for you to realize or current ...

I gotta say AUSCE, your numbers are way off. Copper plugs are usually recommended to be changed every ~15k miles, and usually can go much longer if you regap them. Platinum plugs are rated for 60k miles and Iridium plugs are good for 90k miles I believe.

so should I go with platinum or iridium and what gap since Ill be testing it a bit for performance?

will not give you a lot of power but should improve combustion ...

Hey, I just wrote up a how-to about tuning up your aveo from stock plugs. Like you I waited way to long (81k). I used new wires and autolite platinum plugs and they made a noticeable difference in acceleration and in startup. like others have said, if you want to go with copper plugs, you just have to change them out more often. but the better metal plugs like platinum or iridium will last longer, which for you and I is a good thing since we like to procrastinate! lol. get them things changed and youll see what I mean.

[Daox]

You can go with whatever type you want. The platinum/iridiums will just last longer.

As for gap, just use the stock gap. You haven't done any work on the engine or ignition system to be messing around with it. The stock gap is optimal for the stock engine.
