has discovered a number of Genuine BMW parts and accessories which can make outstanding upgrades to your BMW as direct replacement parts or OEM quality upgrades accross BMW models. The OEM E36 OBDI M50 Manifold is one of such kind of parts.

As always, changes were made to the E36 platform when cars went from OBDI to OBDII in 1996. In many cases, some of these changes resulted in the 1995 OBDI M3 possessing a performance advantage over the newer OBDII E36 M3s from 1996-1999 mostly due to emmissions restriction laws.

One of the changes toward the lower power side of the spectrum involved the E36 OBDII M3 manifold being airflow restrictive compared to the OBDI manifold, which, in a performance M3, or BMW tuning application, at some point becomes a limiting factor.

This restricted air flow problem can be corrected, and opened up by installing an OBDI M50 M3 manifold onto an OBDII M3, resulting in approximatey twice the runners capactiy, increasing airflow and fuel mixture capabilities.

To accomplish this conversion from OBDI to OBDII a number of differences between the two manifolds and their linkups and mechanics must be accounted for. There are currently two ways to do this.

The M50 Manifold Basic Conversion kit includes all of the components required to covert your OBDII M3 over to an OBDI M50 Manifold, however it requires more mechanical inclination on the part of the installer, and is a less elegant solution than the other conversion kit option available, the Eurosport M50 Manifold Conversion kit.

KO Performance carries both kits, which basically boil down to a choice on the part of the purchaser between a less expensive, basic kit, or a custom manifold interface that is super clean, designed for perfect fitment conversion, and more expensive. Either way you go, our M50 Manifold Basic Conversion kit includes the M50 manifold, which is required for the Eurosport Conversion kit as well, at much better pricing than you can find the M50 manifold by itself without the Basic Coversion components. You can't go wrong!

We installed the M50 Manifold conversion kit on our E36 1997 Dinan Base, KO Stage III Boosted Supercharged M3 and saw an additional 32 rear wheel horsepower on the dyno from this modification alone (see dyno to the right). On our track car, we used the Eurosport M50 Manifold Conversion kit, which we also sell, instead of the Basic Conversion Kit for the cleaner look (see pic on right, installed on our track car with our KO Vortech Supercharger Boost Kit)
