Fitment Comes First
We look at engine code, chassis, production date, size and other application details that can change which internal engine component is correct.
Internal engine parts are too important to order from a vague fitment claim. We focus on the details that actually determine whether a part belongs in your engine—manufacturer part numbers, engine codes, production differences, chassis information and component size.
European vehicles often share model names while using different engines, production revisions or component specifications. Our approach is built around identifying the part itself—not forcing every application into a broad year, make and model match.
We look at engine code, chassis, production date, size and other application details that can change which internal engine component is correct.
Manufacturer, part number, component type and available size variants are presented as clearly as possible so you can compare them with what you already have.
When manufacturer application data is available, it is our primary reference. Secondary sources can help confirm a fitment claim, but they do not replace the underlying part data.
Manufacturer, part type, part number and available specifications.
Engine codes, chassis, production differences and manufacturer catalog information.
STD, undersize, oversize or other size-specific information when applicable.
If the available sources disagree or more information is needed, we tell you instead of presenting uncertain fitment as guaranteed.
Some European engine components are commonly used across several applications even when the available catalogs do not fully agree. In those situations, we would rather clearly flag the discrepancy than quietly expand or narrow the application list.
Year, make, model, engine code, manufacturer part number or the part you are replacing—we’ll help you review the application before purchase.
