BMW 330d Parts & Accessories

The BMW 330d is one of the most acclaimed performance diesels ever built, pairing the M57 or N57 3.0-liter turbodiesel inline-six with the 3 Series platform for a combination of genuine sports car performance and diesel economy. Available across E46, E90, F30, and G20 generations, the 330d consistently delivers benchmark diesel driving dynamics that reward modification.

Popular Upgrades

An ECU remap is the most impactful 330d upgrade, typically adding 40-60 hp and 80-100 Nm on the N57 engine. A performance air intake improves turbo response and complements the remap, while coilover suspension and upgraded sway bars transform the 3 Series chassis from GT tourer to a genuinely sharp sport machine. Decat downpipes significantly improve the 330d's exhaust note and top-end power.

How much power can the BMW 330d N57 produce with Stage 2 tuning?

The stock N57D30 produces 258 hp and 560 Nm. A Stage 1 remap typically yields 290-310 hp and 600-640 Nm. Stage 2 builds adding a larger intercooler, high-flow intake, and decat can push 330-360 hp and 680-720 Nm on a healthy N57, making it one of the most potent diesel tuning platforms available.

What is the best coilover kit for the BMW 330d?

Coilover kits with adjustable damping and spring rates allow the 330d to be tuned for street or track use. The N57 diesel's extra front weight versus petrol variants means front spring rates should be slightly higher than the standard 320i specification. Look for coilover kits specifically rated for six-cylinder diesel E90/F30/G20 variants.
