Why ACDelco Is the Right Choice for Your GM Vehicle
Share
If you own a Chevrolet, GMC, Buick, or Cadillac, ACDelco is your factory parts brand. Here's why sticking with ACDelco parts — particularly spark plugs and oil filters — makes sense for your GM vehicle.
ACDelco's Relationship With GM
ACDelco is General Motors' genuine parts division. When GM engineers design an engine and specify a spark plug, that specification is what ACDelco builds to. The result is a part that's engineered to work with GM's specific ignition timing maps, compression ratios, and combustion chamber geometry.
ACDelco Spark Plugs
ACDelco's Professional Iridium spark plugs are the OEM specification for most modern GM engines including the EcoTec3 5.3L and 6.2L V8s found in Silverado, Tahoe, and Sierra. They offer 100,000-mile service intervals and are designed to maintain their performance characteristics throughout that entire service life.
ACDelco Oil Filters
ACDelco oil filters are engineered for GM's oil passages, flow rates, and pressure specifications. The bypass valve opens at exactly the right pressure. The anti-drainback valve is sized correctly for your engine's startup requirements. These details matter for engine longevity.
The Price Advantage
ACDelco parts from independent suppliers like Texan Supply are the same OEM-quality parts you'd get from the dealer — at a significantly lower price. Skip the dealer markup without sacrificing quality.
