The XJ 5.0 V8 Supercharged uses the AJ133S — a 5.0-litre supercharged V8 petrol engine. It was fitted from 2009 to 2019 across the X351 generation, representing the flagship performance option in the XJ range alongside the naturally aspirated 5.0 V8 and the supercharged V6 models. The AJ133S is part of Jaguar's Gen III AJ-V8 family and shares the same timing chain tensioner design pattern as other JLR vehicles of this era.
