Don't buy cheap plugs

[ls1camino]

This is why you don't buy cheap spark plugs. I was getting random misfire codes in the GTP, so I pulled the plugs and this is what I found. Number 3 and 5 are toast.

[FSANE]

what name brand are they?

[Dewman]

look like ac delco to me

[wheeliE-maxx]

I tried accel u-grooves when I first got my truck. The whole ceramic insulator along with the electrode broke off. So the plug was completely hollowed out. Still ran alright with new ngk's after. The cylinder may be gouged to hell when I take the heads off though

Wouldn't call delco's cheap plugs...maybe you have some detonation and it's not the plugs fault. Doesn't delco make NGK's?

i think that they do...either ngk or champion. i do know that autolite makes motorcraft...not that that has much relevance here.

and by no means are delcos cheap plugs. they retail on average $1 -$2 higher per plug across the board of comparable plugs.

What I was thinking ^. When did a AC Delco plug fall into the category of "cheap" or a bad plug? I think the GTP has other issues.

I think the GTP has other issues.

That may be possible, if it destroys these plugs (Autolite 104s), then I'll look into finding out what the bigger problem is.

After the plug change though, I went to work, and on the way, the car accelerated a lot better, and actually broke 140 without batting an eye...in the past few weeks, it's been a struggle to get to only 125.

[ls1camino]

Oh and the plugs go...2-1-4-3-6-5...not sure why I did it that way

[Y2KPewterSS]

Buy weaponX plugs and you wouldn't have any issues.

[EnjoiJoe]

weird i have never had a problem with my autolite 104s

Cheap plugs for cheap cars, good plugs for good cars imo.









So yeah, I steal plugs for my thidgen out of lawnmowers.

No no, that's what I just replaced these AC Delcos with.

Did you have to go with a cooler spark?

Like I said, it pulls really hard now. As a comparison, I barely beat a riced out 3.4L Grand Am last night...it was pitiful.

Yah. Running on 4 cylinders will do that to ya.

*sigh* yeah

[cammed goat]

Well, hopefully these plugs will last longer.
