Changing spark plugs?

I have 52000 miles on my HHR and I was checking to see if anyone has done their tune ups? How easy it was to change out the plugs and which ones out there are good? Any info would be great..

Merry Christmas!!!

Not too bad. You have to remove the air intake cover. And you will need an extension for the socket.

The spark plugs have a life of 100,000 miles so you are a little more than half way there.

Thanks for the info...it's just I've seen people changing or upgrading at 25000.I thought it would be good idea to change them early. Any good brands for a upgrade?

The last car I owned had 100,000 mile plugs which were in poor shape at 60K miles. I'm planning to replace them in the HHR at 50K miles..cheap insurance in my book.

Very easy job to do on these cars. I'd stick with AC Delco plugs and swap em out every 50K or so. Sure they'll still be working at 100K but will most likely be all carboned up and the gap will likely be way off by that point.

Spark plugs like oil are a lot better then the ones from years gone by. If everything else is in good shape the plugs will go the 100,000m easy.
Like people that change oil at 2500-3000 miles. To each his/her own

Agree - when I was working at a garage I and most of the Mechanics ran their vehicles on prematurely yanked plugs. But, I never tried running on used oil, had to draw the line somewhere

Plugs can last for 100,000 miles due to emission warranties.

But I find it best to change them at 50,000 miles just to make sure still be able to remove them without ripping the threads out of the head.

Most plugs come out easy but every once in a while [Toyota] I would get one that did not like to come out of an Auminum head. I found that removing them at 50,000 I never have any issues. But with 80,000 or more I would get a tough one now and then.

The worst is the front side plug on a Pontiac Fiero V6 as the water ran down on that side rusting plugs in. Mine have not been an issue since my first change as the car is rarely in the wet anymore. I wax it more than wash it.

Always put anti seze on the threads before installing.

I put new plugs in but if you cheap you can use the old ones if they appear normal for wear.

Long reach plugs in the old Olds 215 ALuminum V8's from the 60 were a tough removal too.
