Ensure your vehicle maintains optimal fuel efficiency and performance by swiftly replacing the Mass Airflow Sensor (MAF). This crucial component regulates fuel delivery through injectors based on incoming air volume. A faulty MAF can significantly impact gas mileage and overall performance.

Gradual MAF failure often results in reduced fuel efficiency and performance degradation. Complete failure may cause stuttering and stalling, forcing the vehicle into a limp mode. A simple diagnostic test involves unplugging the MAF connector before starting the car; improved idling indicates a faulty MAF requiring replacement.

Failure to replace the MAF leads to excessive fuel consumption and inefficient burning, adversely affecting fuel economy. Opt for a Genuine BMW MAF replacement to ensure stock-quality performance and enhance vehicle efficiency.

This K&N performance cold air intake kit eliminates the restrictive air box in favor of a high flowing intake system that allows for greater power all throughout the power band. Every K&N intake features a premium air filter that is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance intake filter. These are very easy to remove and maintain. Turner Motorsport recommends this as one of the first maintenance/modifications you make to your vehicle after you purchase!

K&N's air filters allow increased airflow - dirt and particles stick to the oil on these filters, making them more effective than traditional paper filters in terms of protection. Additionally, K&N believes their filters are more efficient than paper filers - this means more oxygen getting into the engine, allowing vaporized fuel to burn more efficiently and increasing horsepower and fuel economy. The best of both worlds!

  • Covered by the K&N Million Mile Limited Warranty
  • Washable and reusable
  • Will not void vehicle warranty
  • 50 state legal

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

Maximum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 1.6mm powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

aFe has reported gains as high as 20 hp and 27 lb/ft torque on the 330i

For the maximum benefit in performance, we recommend upgrading your engine software with the Shark Injector (Click here for more info on the Shark Injector performance software.)

This aFe intake fits the following BMWs:
2003-2006 E46 3 series : 325i 325ci 325xi + Wagon & Convertible models with M56 engine
2001-2006 E46 3 series : 330i 330ci 330xi + Convertible
2004-2006 E83 X3 : X3 3.0i

Clickhere for installation instructions.

Want an extra layer of defense? Add a pre-filter to prevent water, mud and sand from congesting your air intake system. This simple upgrade slides over the aFe filter of this intake kit, much like a sock, giving you an extra layer of defense, and extending the cleaning interval of your aFe intake's filter element. Best of all, using the Pre-Filter does not significantly diminish your air filter s performance the smooth rush of oxygen keeps rolling right into your engine. To add the pre-filter, just select the option for the drop-down option below.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. Don't forget to order a valve cover gasket to make your separator change easier.
