BMW 3.0S Parts & Accessories

The BMW 3.0S is the carbureted E3 large sedan variant fitted with the 3.0-liter M30B30 inline-six, offering a significant step up in smoothness and power from the earlier 2500 and 2800 models. These early-1970s luxury sedans represent classic BMW engineering at its most refined and are popular with discerning collectors.

Popular Upgrades

The M30B30 in the 3.0S responds well to performance exhaust headers and an improved cat-back system that improves gas flow without altering the car's dignified character. A complete suspension refresh with polyurethane bushings and quality shock absorbers transforms the chassis, while stainless brake lines and new pads restore confident stopping.

What carburetors does the BMW 3.0S use?

The 3.0S uses Zenith carburetors in its standard tune. Many owners upgrade to dual Weber 32/36 or Solex carburetors for improved throttle response and easier tuning. Carburetor rebuild kits for both the stock and Weber setups remain available from specialty suppliers.

How hard is it to find parts for the BMW 3.0S today?

M30 engine internals are broadly available across the entire 2500-3.0Si family. Chassis-specific parts like E3 body seals, trim pieces, and specialized suspension components require more searching, but a dedicated network of BMW Classic dealers and specialty restorers keeps supply reasonably healthy.
