You can't tune the 08 so that's out of the question assuming you have a 3800 of course.

I didn't realize that.

do not get them bosh +4 plugs, your car will hate them.

use iridium plugs or copper core plugs. i like the acdelco's myself, some like the NGK's. iridium plugs is what your car came with.

I stick with AL605's had a bad experience with NGK although your n/a so maybe tr55's -ngk or AL606 up to you really. coppers need replaced more often keep that in mind to as our cars are not the simplest plug change

the iridium plugs will last up to 100,000 miles. like they should, the copper core plugs last 10 to 15,000 miles, so a yearly plug change is the norm. and the copper core plugs run about 2 bucks each.

I change my copper core plugs about every 20k miles. Super easy plug change

Please do not use Bosch plugs or O2's in your GM product. For some reason they have issues much more often than other brands. Denso is a great O2 and last I checked.. Rockauto had them for $35.

I've never heard of bosch problems, they're probably the best aftermarket for o2 sensors that I know of. I wouldn't buy their plugs though. Is denso the oem brand?
