BMW 330Li Parts & Accessories

The BMW 330Li is the G28 long-wheelbase 3 Series, developed primarily for the Chinese market where rear passenger space is a priority. Powered by the B48 2.0-liter turbocharged four-cylinder, the 330Li combines modern BMW performance technology with an extended wheelbase for improved rear comfort, while sharing the G20 platform's broad aftermarket support base.

Popular Upgrades

The B48 engine in the 330Li responds strongly to Stage 1 ECU tuning, typically adding 40-50 hp and 60-80 Nm over the factory 258 hp output. A cold-air intake complements the remap, and G20-compatible coilover suspension improves handling significantly, with front fitment shared across the standard and long-wheelbase variants.

What engine is in the BMW 330Li and how tunable is it?

The B48B20 in the 330Li produces 258 hp and 400 Nm in standard tune. The B48 is one of BMW's most tunable modern engines, with a robust Stage 1 map yielding approximately 300 hp and 450-470 Nm. The B48's strong internal components comfortably support these outputs without hardware changes.

Can G20 suspension parts be used on the BMW 330Li long-wheelbase?

Front coilover components are compatible between the standard G20 and the long-wheelbase G28 330Li. Rear suspension geometry differs due to the extended wheelbase, so confirm rear fitment with the suspension manufacturer using the specific G28 chassis code to ensure correct spring rates and strut travel.
