sparkplug change

[harrison32]

my 08 gt has 38,000 miles....when should i change my sparkplugs and the best to use..

Stock motor or forced? I have a supercharger and I have to change them out every 30,000. If you don't have forced induction then I believe the service calls out for every 90,000

Oh yeah I think auto light ht1 are recomended for your car also. Could be Wong

You really do need to read the manual...08's have two different styles of plugs; the heads changed in the middle of that model year.
