BMW Engine Performance Packages for BMW 5 Series E39 (1996-2003)

Clear BMW chassis

Please ensure your correct model is selected

Since 1993 Turner Motorsport has been at the forefront of performance tuning for BMWs. We show this best in our tuned Performance Packages, developed along stages for specific BMW models. Each staged Package is tuned in-house, bringing together expertise from our street tuning division, service shop, and race team. Nearly all of our Packages feature custom-tuned performance software from the best names in the business. The software is the best feature in our kits, maximizing power gains while doing nothing to affect engine reliability or driveability. In most cases, Stages are upgradeable - you can jump from one stage to another by purchasing the new parts and revised software (contact us directly about buying parts outside of the Stage). Or jump right into a higher stage by purchasing the complete kit. We'll work with you to select the appropriate parts and a matching software tune. Nearly all of our Packages have been tested and tuned on our in-house Dynapack Chassis Dyno. Our packages are designed for US-spec models only.

1999-2000 E39 528i Stage 1 Performance Package
Peak Power Gain: +14hp / +11ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is a cone filter with a heat-blocking shield around it. The larger surface area of the filter, combined with the heat shield, allow more cool air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

1999-2000 E39 528i Stage 1 Engine Upgrade includes:
aFe Cold Air Intake (filter, heat shield, intake tube)
Shark Injector performance software

Peak Power Gain: +18hp / +20ft-lbs
Rev limit: 7400
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and performance software. The aFE intake is made from high-quality materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe's Stage 2 Intake uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, ABS plastic intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash.
