I know we have the GM 100,000 mile spark plugs in our cars(which are nice) but is there a better plug i could get for my 2.2 that might off a tiny gain of hp or something? or is getting added performance from a plug not possible. anyone have proof or dyno's of increased hp from different/better plugs? thanks guys

I don't know if the pulstar would give our vehicle 5hp or more honestly,maybe 3hp,and most likely better fuel economy.

I agree, 3hp is probably more like it. It's been proven to reduce choppy idle also, but like I've said before.... An ignition system is only as good as its weakest link. For your everyday driver, I'd say just stick with platinum plugs because $100 for plugs is kinda crazy.

I honestly doubt there a gimmick. DC magazine did tests on these plugs on three different vehicles and the results were good

i think we all know. so even with the GM plugs in whats the best mileage to change these maybe the next oil change?? I'm at like 34000 and just changed my oil at 9% life



Talking about oil life... Im using natural oil if i switch next time do i have to do anything so the computer knows its synthetic, or does it read the same?

anddd why dont i get the little gray "blah blah added 30 sec later" thing? lol

it's a post merge, it does it automatically

as for the synthetic switch, just do it, there is nothing extra you have to do. Remember this though, it's more expensive, and once you switch, there is no turning back.

lol kinda made it sound like an epic thing. okay i guess next time is it. as far as cost i heard that since synthetic lasts longer it pretty much balances out.

you got that right, run it till the change oil indicator tells you to, then change it. The cobalt's oil life indicator was designed around the use of the synthetic motor oil, so it is set up to go off it. Information given to me by a GM Certified technician from one of the plants where they built the cars. Cant remember which one tho:confused:
