BMW M50 OBD1 Intake Manifold e36 e46 e39 M52 S52 m54 Upgrade swap manifold !

**M50 manifold, originally found on OBD1 BMW engines  1992-1995 325i 325is 525i and 1995 M3 3.0L** **Part # 1 735 728-2,5** ****The manifold is in good working condition .**** ****Comes with mounting brackets, hose's, and iat sensor**** ****Some typical ware/tare from being over 30 years old .**** ****(scratches, scrapes, dirt, grime,oil ect )**** **The **M50 intake manifold swap**** **is a popular modification for M52, S52, and M54 engines to increase** **high-RPM horsepower, as the M50 manifold has larger, less restrictive** **runners than the OBD-II manifolds.** **The swap typically requires a** **conversion adapter kit to ensure proper fitment and functionality of** **various components like the oil separator and idle control valve.** **Performance Benefits** **The** **M50 manifold, with its larger plenum and wider runners, allows the** **engine to breathe better at high RPMs, which is a significant advantage** **for performance driving and track use. The stock M52 and S52 manifolds** **were designed with narrow runners to enhance low-to-mid-range torque for** **street driving, which ultimately chokes the engine at higher speeds.** **- **Horsepower Gain**: Dyno tests have shown gains of 15-20 horsepower on M52 and S52 engines, primarily in the upper RPM range with supporting mods.** **- **Torque Trade-off**:** **The gain in high-end power comes at the cost of a slight compromise in** **low-end torque. This power band shift makes the modification ideal for** **track cars but less suited for daily driving where low-end torque is** **more often used.** **- **Aesthetic/Practical Benefits**:** **The swap can free up room in the engine bay, simplify intake tubing,** **and potentially reduce the chance of boost/vacuum leaks in forced** **induction setups. It also removes the problematic stock DISA valve found** **on some M54 engines.** **Verify fitment before purchase. Do your research this is a very common conversion with lots of information online.** **If you have any questions feel free to message us.**
