This Sangyue four-sensor set includes both upstream (pre-catalytic converter) and downstream (post-catalytic converter) sensors engineered to match the electrical and mounting specifications of many Chevrolet, GMC, Cadillac, Pontiac and Saturn models from 2008–2014. Each sensor is built for plug-and-play installation on the listed vehicles; checking vehicle fitment before purchase ensures correct compatibility.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines will these sensors fit?\u003c\/h3\u003e\n\u003cp\u003eThis kit fits a range of GM full-size trucks and SUVs and some passenger cars.
