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): For products listed to suit a specific vehicle, our fitment data 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. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing. If you have any doubt, please message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm before you buy.
