As far as spark plugs, most will recommend the ACDelco spark plugs that are cars come with (some of us use different plugs), and the boots you can buy from Autolite or BWD (I use the BWD). The only other thing you can replace is the module and the coil pack, but thats hardly ever necessary from what I hear, and they're expensive items to replace as well.
thx guys....i change the oil every 4500 miles or so and the air filter has been changed twice. i figured the most i would need is plugs and wires but wanted to make sure. hopefully this weekend i can swap em
I would go to summit racing and order the E3 spark plugs, i ordered them and put them in and i get better gas mileage than before and it starts up a bit quicker and runs a tad smoother but thats just me. They dont have them listed for a 2.2L cobalt, but i called them and they got ahold of the company and sent me the ones i need. about 36 bucks shipped and you get a free hat and catalog, its not bad
Why are you doing a tune up at 30k? The plugs we have in our 2.2 are iridium plugs that can last up to like 100k. Just saying it's up to you. I would recommend a fuel filter and maybe a tranny filter and fresh fluid if it's an automatic...again our cars tranny service is 50k. I plan on doing my tranny and fuel filter every 30k. But I'm not plannin on touchin the plugs unless I have too. That's just me.
I've been looking for fuel filters myself, but everywhere I go I can't find one, was thinking of going to the dealer, but I know they'll charge a lot for that, can anyone reccomend where I can find one?
its just like anything else its preventative maintenance you are there inspecting the spark plugs anyway, for the $12 it costs to get new spark plugs you mind as well replace them. and if you read the service manuals they say to inspect and replace if necessary which you should check your spark plugs more often then 100k miles.
