As with any automotive component, correct fitment depends on the exact chassis code, build date, engine variant and factory options fitted to your vehicle, so please cross-check the reference numbers below against your vehicle's existing part before ordering.

Reference part / OEM numbers associated with this listing include K04-025. These numbers are provided as a cross-reference guide only and should be checked against the part currently fitted to your vehicle, since manufacturers periodically update part numbers across production runs.

Whether you're a workshop completing a repair or a DIY owner tackling the job yourself, this listing is intended to make sourcing the right part straightforward, without the guesswork or long overseas shipping times that often come with importing parts directly.

If you are unsure whether this is the right part for your vehicle, our team is happy to help you confirm fitment before you place an order. We aim to keep every listing on our store accurate and up to date, and welcome any questions about the specifics of this particular product ahead of purchase.

Every listing on the Auto Centre Parts site is checked against the manufacturer or reference information supplied for it before it goes live, and our team reviews fitment questions individually so you can order with confidence rather than guessing whether a part will suit your vehicle.
