This weighted shift knob makes shifts faster and the extra-large globe shape encourages over-palm shifting. The Black Forest Industries Billet Knob weighs in at 8.8oz (250g), about twice as much as a stock knob and a little heaver than the BMW ZHP knob. The heavier knob amplifies the pendulum motion of the shift lever resulting in smoother and faster shift times. BFI has designed this knob for BMW and VW fitments to fit snug on the shift lever and be secured with Allen set screws. They were careful to reduce tolerances compared to universal knobs. The overall height of the BFI knob is the same as stock anatomic knobs (some BMW M/Performance models have a stock knob that is shorter than this one).

Included with the BFI Billet knob is a matching BFI crest shift emblem. A 5 or 6-speed pattern emblem is available separately.

Choose from soft alcantara or perforated air leather with either a silver or black anodized base.

This is a simple kit to make it easier for you when removing your AFM/MAF when using a MegaSquirt ECU. In many cases, the air temperature sensor is built into the MAF, so removing it will require you to install an IAT Sensor somewhere else in the inlet tubing. This kit gives you the bits you need to do that.

BMW E30 1987-1993 E30 325i / E32 / E34 MS3Pro PNP ECU aka MSPNP Pro Plug and Play Standalone Engine Management System *Fits multiple BMW models: 1987-1992 325i (E30 Chassis with M20) * 1988-1992 735 (E32 Chassis with M30) 1989-1990 525 (E34 Chassis with M20) 1989-1993 535 (E34 chassis with M30) 1991-1993 M5 (E34 chassis with S38) *Note: This does not fit BMW e30 325e models with the eta engine (except the 1987 “Super Eta”), or the 1992 E36 chassis 325i with the M50 (in 1992, the convertible used the E30 chassis, while coupes and sedans received the new E36 chassis). These used a different ECU design. Additionally, some European 325i models for the 1987 year used an ECU with a part number of 0 261 200 073 or 0 261 200 081; this ECU is not compatible with the stock wiring on these cars. Also, this MSPNP may not work with automatic transmissions on the E34 or E32 chassis, which rely on the fuel consumption signal for the transmission computer. Automatic equipped E30s using a hydraulic transmission will work without issue. This MS3Pro based PnP ECU takes plug and play engine management for your BMW E30 / E32 / E34 to the next level!
