Which vehicles and OE numbers does this sensor cover?

This Marsflex TPMS model matches a wide range of GM makes and model years, covering many Chevrolet, Buick, Cadillac, GMC, Pontiac, Saturn, Saab and Hummer applications. It is intended to substitute several original equipment part numbers, enabling cross-fitment across older and newer GM platforms.

How easy is installation and programming?
