BMW E46 Performance Intake Kits

BMW E46 Performance Intake Kits The BMW Performance line of intake kits deliver power gains with exceptional engineering and good looks. BMW Performance Intakes are designed to take advantage of a larger air filter to gain more cool air for the engine. The cooler and denser air will develop more power and torque. BMW engineers this kit for a perfect fit with materials and design consistent with the rest of the engine bay. With a factory-designed performance intake you get the power gains of an aftermarket kit blended with style and engineering direct from BMW.

Performance Air Scoop & Air Filter - E46 M3

Replacement air scoop and filter to restore the power you love from your intake system. 

Eventuri was founded by true enthusiasts who had a shared passion for cars and performance. Engineers that had a background in Aeronautics as well as automotive tuning. After experiencing disappointment time and time again from the claims set forth by the automotive aftermarket, they set out to raise the bar. Their goal was to set a new benchmark for intake design providing true gains, not just "claims."

Designed to use the "venturi effect," Eventuri has created a unique intake system that out-performs the competition. The Venturi effect is when the smooth reduction in cross-sectional area along the length of the housing causes the airflow to increase in velocity. This means more air-flow and smoother delivery, resulting in more power. But that isn't all that sets their design apart. They also use an inverted cone filter that is decoupled from the MAF. This is done because it means the filter no longer dictates the shape of air-flow, thus creating the venturi effect.

Active Autowerke Methanol Injection System - E46

Turbo vehicles often suffer from heat soak - methanol injection systems help cool the intake charge, and increases your engine’s knock limit – giving you a failsafe against high boost detonation. Active Autowerke's methanol-water is precisely delivered and metered by its own electronic module, which measures boost pressure within the engine and controls the delivery flow to match both the engine load and demand as needed.

  • The large 1.8+ gallon reservoir
  • Rigid mount can be easily detached if needed by its spring loaded quick releases.
  • For offroad use only.
  • Does not include any fluid.

This methanol injection system fits the following BMWs:

Their systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dyno testing. They strive to publish all the development information to illustrate the depths they go in bringing an intake from concept to reality. Also assuring to only use the highest quality components for style and durability

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
