41 reviewed application examples across 9 model families. These are selected UK catalogue facts, not complete vehicle coverage or an automatic fitment check. The source is the manufacturer’s 2024 UK PDF, still linked from its download page when checked on 8 November 2026. Recheck the current NGK UK Part Finder before ordering.

Choose the complete application, including generation, engine code and variant. An engine name or registration year alone is insufficient. These examples exclude diesel, pure electric, racing and modified engines. Hybrid examples are labelled individually.

No application selected. Offers are reference comparisons, not confirmation that a part fits your vehicle.

Coverage, overlaps and unresolved evidence

The examples retain bounded dates and exact engine details. They do not certify a particular VIN, supersession, fitment or installation procedure. A reference not shown here is unknown, not incompatible. Date ranges can overlap: resolve the complete variant and original specification with the manufacturer or supplier.

The Yaris 2020-on row is withheld because its engine/cylinder details need clarification. Older Duster references lacking an engine code are not used to recommend modern Duster parts. Open-ended catalogue date ranges have not been extended to today. No source artwork, complete catalogue, private fitment feed or invented vehicle match is published.

A standard and upgrade reference are separate catalogue fields, not a price or quality ranking. Retailer offers retain their own observation dates; catalogue review does not refresh a price. Check exact part number, stock number, pack quantity, delivery and returns with the retailer.
