For over 100 years, ACDelco has been recognised as a world leader in the automotive aftermarket.
ACDelco provides a wide range of quality products for the automotive replacement parts industry, including batteries, spark plugs, oil filters, air filters, wiper blades, and brake components. ACDelco also offers a comprehensive range of oils, fluids and cleaners.
As a global leader in automotive replacement parts and related services, our focus has always been on building a reputation as the number one source for quality auto parts to suit most makes and models. We have built a worldwide reputation as a premium source for experience, dependability, technology and performance.
Packaging: Manufacturers periodically update their packaging and labelling. You may receive the current or a previous design — the product, formulation and part number are unchanged.
Fitment (vehicle-specific products): Vehicle fitment is based on manufacturer and supplier catalogue data and is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant, and parts on older vehicles may have been replaced with non-original or different-style components.
Before you buy, compare the product images with the part currently fitted to your vehicle — check shape, size, connectors and mounting points. If the part on your vehicle looks different, please contact us before purchasing. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing.
Not sure? Message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm fitment before you buy.
Parts returned because they do not suit the vehicle, where the listing matches the manufacturer's catalogue, are treated as a change of mind and must be unused, uninstalled and in original packaging. Nothing in this notice affects your rights under the Australian Consumer Law.
