The XK 5.0 V8 uses the AJ133 — a 5.0-litre naturally aspirated V8 petrol engine. It was fitted from 2005 to 2014 across the X150 generation. The AJ133 is part of Jaguar's third-generation AJ-V8 family, and its timing chain tensioner design is the subject of a documented class-action lawsuit covering this exact engine across multiple JLR models. The XK 5.0 V8 is no longer in production, but we continue to rebuild and replace engines for every one still on the road. Jaguar XK 5.0 V8 Engine Compatibility The X150-generation XK 5.0 V8 uses the AJ133 engine throughout its production run. Before we quote or supply anything, we confirm: Your exact engine code via registration or VIN Your generation (X150) Drivetrain and ancillary specification Any electronics or ECU considerations specific to your exact build This is why we always start with your registration rather than a generic XK quote — it protects you from paying for parts that don't fit your actual car.
