Icm
The ICM is about 80 bucks at the dealer and Autozone. I happen to have one Ill let it go for $40! They can get screwed up by the heat coming off of the head. Make sure you put compound paste in between the module and the metal harness. Or space it away from the head.
i know i only use AC delco.. i tried a fram oil filter and it leaked like hell, i put an AC filter in and it doesnt leak..
That being said used for $30 as long as it works will do, or $66 for one BRAND NEW AC DELCO From DAL
