One thing drivers and cars have in common is the need for air. Induction systems provide a third of the critical necessities for engines to run, so giving your BMW the best way to breathe is paramount in engine performance. If you need to replace your filter, recharge your reusable pod filter, or upgrade your intake, turbos, or intercooler parts, everything can be found below. We have OEM replacements as well as aftermarket performance upgrades to keep your BMW pristine, powerful, and functioning at peak 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 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

    Increase the power of your vehicle by utilizing a water/meth injection kit. The purpose of water/meth injection is to reduce combustion temperatures and allow you to run higher boost pressures on pump gas. When using meth injection, pump gas will resist detonation much better because the methanol essentially raises the octane rating of the fuel and will allow you to run much more aggressive street tuning. This AEM kit has more features and components than any other comparably priced injection kits on the market. 1 Gallon tank with built in low level switch Boost referenced progressive controller “Boost Safe” readiness safety system Check valve integrated into nozzle to prevent unintended fluid flow One injector and two nozzles to cover a wide range of HP levels High Pressure 200psi Recirculation-style pump Progressive Controller: Start Injection Boost 1-11psi. Full Injection Boost 6-39psi LED dash light for system status and low fluid warning 20 ft. of injection tubing
