BMW 320d Parts & Accessories

The BMW 320d is one of Europe's most popular performance diesels, delivering genuine driving satisfaction alongside exceptional fuel economy across E46, E90, F30, and G20 generations. The M47, N47, and B47 turbodiesel four-cylinders are among the most modified diesel engines in the world, with a massive aftermarket backing every generation.

Popular Upgrades

A Stage 1 ECU remap is the most impactful single upgrade for any 320d, adding 30-50 hp and 70-100 Nm on the N47 and B47 variants. Performance air intakes and downpipe upgrades further improve turbo response, while coilover suspension and upgraded sway bars transform the 3 Series chassis from relaxed GT to sharp sport machine.

How much power can a BMW 320d make with a Stage 2 tune?

A Stage 1 N47 or B47 typically delivers 185-200 hp and 420-450 Nm. Stage 2 builds adding a performance intercooler, high-flow air intake, and decat downpipe can push output to 220-240 hp and 480-520 Nm while maintaining street reliability. Reputable tuning is essential to protect the diesel particulate filter and high-pressure fuel system.

Which suspension upgrade works best for a 320d daily driver?

For a 320d used primarily as a daily driver, a street-oriented coilover kit with 10-15 mm drop delivers noticeably sharper handling and improved appearance without sacrificing ride quality. Adding front and rear sway bar upgrades compounds the handling improvement across all BMW 320d generations.
