The F‑Pace P340 uses the AJ300P — a 3.0‑litre inline‑six petrol engine from Jaguar Land Rover's Ingenium family. It was offered as a mid‑range petrol option within the F‑Pace lineup, producing 340PS. The P340 is no longer in production, but we continue to rebuild and replace engines for every one still on the road. Jaguar F-Pace P340 Engine Compatibility The F‑Pace P340 uses a single engine family across all generations — the AJ300P 3.0L I6 petrol. Before we quote or supply anything, we confirm: - Your exact engine code (AJ300P) via registration or VIN - Your generation (X761) - Drivetrain and ancillary specification This is why we always start with your registration rather than a generic P340 quote — it protects you from paying for parts that don't fit your actual car.

We replace timing chains, bearings and gaskets as standard on every AJ300P rebuild. Do you supply used P340 engines? Yes, in some cases a matched low‑mileage used engine is the right option.
