BMW G01 X3 & G02 X4 M40i B58 Stage 2 Hardware Package
Description
Unlock the full potential of your BMW X3 or X4 M40i with this Stage 2 Hardware Package, engineered for enthusiasts looking to maximise performance and sound from the B58 engine platform. Designed to deliver significant gains in power, responsiveness, and exhaust tone, this package combines premium, proven components for seamless integration and long-term reliability.
The kit includes a K&N High-Flow Air Filter (33-3134) for improved intake efficiency, a DCE 5.2" Catless Downpipe with built-in heat shielding for optimised exhaust flow, and a DCE Resonator Delete Midpipe to enhance exhaust note and reduce backpressure. Together, these upgrades form the ideal foundation for custom tuning and Stage 2 calibrations, allowing your M40i to breathe, spool, and perform at its best.
For vehicles equipped with OPF/GPF systems, an OPF Delete Cable and CAN MIL Module are recommended, or professional coding/tuning may be required to remove related fault codes.
