Ready to K-swap your BMW E46? Our BMW E46 K-Series swap kit is designed to make installing a Honda K-Series engine into your E46 as straightforward as possible.
Fits LHD and RHD BMW E46 models.
Honda K-Series engines are known for making great power on stock internals, making them a great match for the BMW E46 chassis.
