BMW 328Ci Parts & Accessories

The BMW 328Ci is the E46 coupe fitted with the 2.8-liter M52TUB28 inline-six, producing 193 hp of smooth, naturally aspirated power in one of the most elegant E46 body styles. The 328Ci occupies the sweet spot in the E46 coupe lineup, delivering more displacement and torque than the 325Ci in the same sharp chassis that has made the E46 a perennial favorite for enthusiasts.

Popular Upgrades

A cat-back exhaust system improves the M52TUB28's already-excellent inline-six sound and frees up high-rpm power. Cold-air intake kits improve throttle response, and coilover suspension on the E46 coupe body with upgraded sway bars creates a chassis setup that transforms the 328Ci from refined GT into a genuinely sporty track tool.

How much power can the BMW 328Ci M52 make with modifications?

The M52TUB28 produces 193 hp stock. A performance exhaust, intake manifold upgrade, and software tune can push output to 215-225 hp while retaining full street reliability. The 2.8-liter displacement also means the 328Ci makes more torque than the 325Ci at all rpm points, making it more satisfying to drive hard.

Is the BMW E46 328Ci better than the 325Ci for track use?

The 328Ci's extra torque from the larger M52TUB28 engine makes it more flexible on track, particularly on tighter circuits where low-rpm pull matters. The 325Ci with the M54B25 has double-VANOS and marginally more modern technology, but both are excellent track platforms with the same suspension and braking upgrade options.
