GM Engine Components offer installer-friendly product categories -- such as intake manifolds, intake manifold gaskets, engine oil cooler lines, tensioners, balancers and pulleys, etc. -- for most GM cars, light-duty trucks and SUVs on the road today. All are OE validated by GM Engineering to assure proper form, fit and function. This is important on these high-labor-hour heavy repairs. The part designs are enhanced to incorporate OE updates, upgrades and Technical Service Bulletins (TSBs). Only GM can offer complete late-model coverage.
