BMW 325is Parts & Accessories

The BMW 325is is the sporty coupe variant of the E30 325i, placing the M20B25 inline-six in the stiffer two-door body for a driving experience that feels even sharper than the sedan. The 325is remains one of the most sought-after E30 variants among enthusiasts who appreciate the combination of a real six-cylinder engine and the coupe's superior rigidity.

Popular Upgrades

A performance cat-back exhaust system transforms the M20B25's inline-six soundtrack and improves breathing at high rpm. Cold-air intake kits and individual throttle body conversions improve throttle response, while E30 coilover suspension and strut braces transform handling into something genuinely track-capable. Upgraded sway bars and polyurethane bushing kits complete a sharp street and track build.

What is the difference between the BMW 325is and 325i sedan?

The 325is uses the same M20B25 engine as the 325i sedan but in the two-door coupe body, which has additional structural stiffening resulting in sharper steering feel and better chassis dynamics. The coupe also received cosmetic upgrades including sport seats and additional trim features over the base sedan specification.

Can the BMW 325is M20B25 be converted to individual throttle bodies?

Yes. The M20 individual throttle body conversion using Weber or Dellorto sidedraft carburetors is one of the most popular E30 builds. Alternatively, a Megasquirt or other aftermarket EFI system with individual injectors and throttle bodies is a more modern approach that delivers strong throttle response and tunability.
