Compatibility & Installation Notes

Always match the engine code shown above against the stamping or label on your original part before ordering. Engine codes are often shared across several models and years with small differences in sensors, mounts, timing components or emissions equipment, so we recommend confirming fitment using your VIN or chassis number – send it to us and we will check it for you. Installation should be carried out by a qualified mechanic. Replace consumables such as gaskets, seals, filters, coolant and oil, and transfer or renew ancillaries as required.

Before You Order

Ideal for Lexus repairs where a direct replacement for the 4AR is required. To avoid delays and returns, confirm compatibility before placing your order by sending us your VIN or the number stamped on your original part.
