Yup......GM has GM products which are thee actual OEM parts and then ACdelco is the closest in quality to OEM parts, pretty much identical just a bit less expensive. Man, if GM wasn't so overpriced I would buy from GM directly. Their prices are just ridiculous and in some cases aftermarket products are actually better depending on the part and which aftermarket manufactuer thats building it bc they correct some flaws that the OEM originally had.

But luckily we have after market manufactuers like ACdelco bc otherwise I would be spending close to $600 if not more to GM opposed to $130 after a $110 core charge to ACdelco. Big difference lol, companies like ACdelco saved me a bunch of money.
