This Euro air intake is less restrictive than the stock intake and also allows much easier acces to the air filter from the top. In addition, this airbox uses a cylinder style filter instead of a standard square filter for higher flow. 

The MAF sensor from your original airbox will need to be reused as the connector in the Euro box is a small 2-pin connector.

Upgrade your BMW N52-powered vehicle with the high-performance E90 330i 3-stage intake manifold. Compared to other N52-powered models, the 330i boasts the highest horsepower due to its 3-stage manifold design. This manifold features two DISA valves that optimize air diversion to the cylinders, maximizing power extraction from the engine.

Key benefits of the 3-stage manifold include:

  • Efficient air distribution to cylinders for enhanced power output.
  • Improved fuel adjustments by the ECU for optimal performance.
  • Bolts onto any N52 version and, with an ECU flash, can add up to 42hp.

The kit includes:

  • 330i intake manifold
  • Both DISA valves
  • Gaskets

For additional power gains, consider purchasing the N52 Euro Air box (ES#2072577) alongside this manifold. Please note that an ECU reflash is necessary for proper functionality of the intake.

Enhance your N52 engine's performance and power output with this comprehensive E90 330i 3-stage intake manifold kit.

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.

For your BMW's optimal performance, ensure the functionality of the hose connecting the oil dipstick to the crankcase vent valve. Positioned below the intake manifold, this hose is susceptible to clogging with oil film and condensation, leading to potential failure over time. Cracks and swelling in old hoses can result in oil and vacuum leaks, compromising engine performance.

  • Essential component for BMW engine functionality
  • Prevents clogging and potential hose failure
  • Minimizes oil and vacuum leaks
  • Convenient replacement when replacing crankcase vent valve

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 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 an oil sludge condition that is impossible to clear. The plastic hoses can become brittle and crack which leads to vacuum leaks and oil leaks. Thankfully, the CCV is replaceable on the early N52 engines (2006 and some 2007 models) 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.

This is a kit containing the oil separator, the vent hoses, and the intake manifold gaskets that are done during a typical oil separator replacement. Complete kit includes:
  • 11617531423, Genuine BMW oil separator
  • 11617559530, vent hose
  • 11157522931, oil separator hose
  • 11157567801, return hose
  • 11157537701, extraction hose
  • 11617547242, intake manifold gaskets (set of 6)
    The intake manifold must be removed to access the oil separator so new profile gaskets are included. We also recommend (but not required) a new oil separator fitting on the intake manifold because it's one of the heated elements that vaporizes the oil as it enters the intake.

    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.

    This kit fits the following BMWs:
    -10/2005 E90 BMW 325xi 330xi - Sedan
    -10/2005 E91 BMW 325xi - Wagon
    -10/2005 E60 BMW 525xi 530xi

    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.
