Holy Cow!! Well heck that is almost high enough to drive clear out here , have us install and do for $130, and drive home. Okay, I am exaggerating, but this is not rocket science, and the price must include a couple glasses of an innocent Cabernet, foot massage, and a colon cleansing. If you want to pay $125 for a fluid change, friction modifier, and a plug install, call DC Performance ( Dan Cragin ) and talk to Tony. He is right there in the S.Cal area, and Dan is still considered one of the best Viper Techs in da World.

I really believe in doing this more often, so check them out and get it done right the first time.
Good Luck !!
