BMW E46 Engine Performance Packages

BMW E46 Engine Performance Packages 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.

E46 330i/ci 03-06 Stage 1 Turner Motorsport Performance Package 3/2003-2006 E46 330i/Ci Stage 1 Performance Package
Peak Power Gain: +12hp / +10ft-lbs
Rev limit: 7000
Octane: 91 or higher

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

The software is also Conforti-tuned and supplied with the Shark Injector software loader. The Shark Injector is a do-it-yourself reflash tool that plugs into the diagnostic plug in the engine bay. 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.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

Turner Plug-and-Play IAT Relocation Kit

All vehicles will lose some degree of performance due to heat soak under the right operating conditions.  Engine management systems constantly monitor operating conditions and modifying parameters based on sensor inputs. BMW integrated the intake air temp sensor in the MAF housing on models such as the E39 M5, and, being sandwiched behind a hot radiator and in some applications next to an even hotter valve cover, this is less than ideal for performance applications. Absorbing excess heat from its surroundings, the MAF can’t shed it fast enough, and the ECU reads an inaccurately high intake air temperature. Compensating for this false hot air measurement, the ECU pulls timing and runs a richer fuel mixture, resulting in a significant loss of torque.

What can you do?  Locate an intake air temp sensor in a location where it can properly measure incoming air temps and where it's less prone to heat soak. Mounting the sensor further away from the heat source and isolating it from the MAF housing, it can both resist the effects of heat soak longer and respond to temperature changes more quickly.  The result is you’ll experience reduced torque loss and more consistent power output when you’re pushing your engine hard. 

The Turner engineering team was initially skeptical of the claimed performance benefits of this modification. They first set out validate the functionality and performance benefit of a temp sensor relocation. Replicating stop-and-go traffic heat soak in a 2001 540i was a simple task in a controlled environment - their dynometer. First the car was heat soaked to simulate being stuck in traffic or moving at low speeds by running the car four times on the dyno with the dyno's cooling fans disabled. The fans were then turned on for three more runs to observe the recovery rate once air flow was reintroduced. The test: following this procedure once with a stock IAT, and once with their relocation kit in place. 

The result? Turner recovered 11lb-ft torque at 2500rpm through use of their relocation kit, with even greater recovery to be found for M5 owners. Here are the heat soak-related torque losses Turner experienced:

Stock IAT location:
18rwtq at 2500rpm
10rwtq at 3000rpm
9rwtq at 3700rpm

Turner IAT Relocation:
7rwtq at 2500rpm
5rwtq at 3000rpm
5rwtq at 3700rpm

The Turner engineering team designed a complete plug and play kit (unlike all other options on the market) that makes for quick, easy, and reversible installation. Weather-sealed connectors keep out the elements, while sheathed wiring offers a clean appearance underhood. With a harness nearly 3 feet long - the Turner IAT relocation kit offers flexibility in positioning, but not too long that you're left with unsightly excess wiring. Turner recommends positioning the sensor in a location away from engine heat, but still within the intake ducting to achieve accurate intake temp readings - such as the far side of the base of the airbox. Vehicles with cold air intakes with cone-style filters can even position the sensor in the end of the filter. Simply drill a hole in your (cool) location of choice and plug in the harness. More information including installation instructions and some good examples of sensor mounting locations can be found in our DIY PDF. 

We include everything you need to relocate your IAT, just select your desired sensor brand below - Genuine BMW or original equipment Beru.

Also the perfect plug-n-play option for anyone looking to upgrade their intake to utilize an Alpha-N tune!

Note for vehicles with M62 engine: applicable to 1999 and up
