K&N's drop-in air intake filter is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance drop-in 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 drop in 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
  • Emissions legal in all 50 states
  • Will not void vehicle warranty

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.

By removing your stock intake air box, you are removing the most restrictive portion of your Z4's intake system, increasing both horse power and torque, improving acceleration as well as throttle response.
11hp max gain, 14 lb/ft torque max gain.

This version uses aFe's highest flowing filter - the Pro 5 R. This filter uses a 5-layer, lightly-oiled cotton gauze material to filter out dirt and particulates, while improving airflow through the intake. For the best flowing filter, with the best performance gain, we always recommend the oiled aFe filter over the dry versions. The Pro 5 R filter is washable and re-oiled using aFe's approved Restore Kit.



Clickhere for installation instructions.

This aFe intake fits the 2003, 2004, 2005 Z4 3.0i (M54 engine)

This Stage 2 cold air intake system produces 18 max horsepower, 15 lbs. x ft. torque over the factory intake. This intake uses a durable, one-piece, 16 gauge, black powder-coated heat shield and a 3-angle adaptor for maximum flow. This air intake system features either a washable/reusable conical Pro 5R air filter for maximum flow or Pro Dry S filter for maximum convenience. This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. This system is finished off with a black powdercoated top for an aggressive, yet stealthy appearance.

By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horsepower and torque, improving acceleration and throttle response, and producing a more aggressive engine note.

Pro5R filter uses a lightly oiled 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

ProDry S filter uses an oil-free filter media for less maintenance. This oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

This aFe Intake fits the following BMWs:
2006-2008 Z4 BMW Z4 3.0i - not for 3.0Si

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.

The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or solid oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create a oil sludge condition that is impossible to clear. Thankfully, the CCV is replaceable on the early N52 engines (2006) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

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.

Due to weak plastic construction, the factory plastic crankcase ventilation breather hose is known to fail. After years of exposure to piping-hot engine bay temperatures and chemical-laden oil vapors, the corrugated plastic tubing can crack, crumble, or fail altogether.

We set out to bulletproof your N52 CCV system with a durable silicone breather hose, designed to provide a comprehensive upgrade and permanent replacement for the factory plastic hose. By replacing the flimsy, heat-hardened OEM plastic hose with a four-ply fluorosilicone hose, you'll experience peace of mind knowing your N52 is free from the inevitable return of oil leaks, vacuum leaks, and drivability concerns that would have been.

This breather hose is found at the front of the engine, and is used to connect the oil separator to the valve cover. It replaces OEM part number 11157522931.

Features:

Silicone construction ensures a durable replacement that is sure to outlast OE plastic
Designed as a direct replacement for the factory breather hose
Retains heating function and OE electrical connector
Design:

Four-ply wire-reinforced fluorosilicone hose is designed to resist degradation due to exposure to oil vapors
O-rings are pre-installed in OE connectors for a lasting seal
Includes pre-installed zinc-coated hose clamps for durability and corrosion resistance
Product Development:

Our Silicone CCV Hose Upgrade was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modelling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.
