We have a lot of N52 powered BMWs in the parking lot here at Turner. No, they're not the fastest cars, and they never will be - but it shines where the more expensive N54 lacks, reliability. There is something innately satisfying about the linear, smooth powerband that comes from BMW's signature inline 6 cylinder platform. We love the N52 for what it is: the perfect daily. And we decided to make it even better by designing an intake that eliminates restriction and increases air flow allowing for max gains of 9 WHP and 13 WTQ down low in the power band. The power numbers are, however, not the most impressive part of this intake. Our intake really makes N52 powered BMWs feel even more linear and predictable, capitalizing on this powerplant's existing strength.

The intake boot is a regular issue especially for BMW's, nearly all vehicles have a boot manufactured from rubber with an accordion section in the design for flexibility. This flexible section is typically where the failure comes from, leading to vacuum leak engine codes, rough idle, and increase fuel consumption. 

When you upgrade to a Turner silicone intake boot you get a perfect fit that will not only outlast the OE design (meaning any vacuum leaks and rough idle), while also smoothing out airflow within the intake tract. This boot also eliminates the factory intake resonator giving your engine a much more aggressive sound under the hood especially at higher rpm. Available in black or Turner blue color, our intake boot offers either a pop of color or a cohesive, complementary look in your engine bay.

The Turner Motorsport silicone intake boot is manufactured with 5 layers of wire reinforced silicone to prevent collapse under load. Engineered in-house utilizing 3D scanning technology, this boot offers perfect fitment with the factory air box and either single stage or three stage (high output N52) intake manifolds.

Install as a standalone reliability improvement or in addition to our three stage intake manifold and Turner performance tune (available here).

Replaces OE intake boot 13717536004.

Features:

  • 5 layers of wire reinforced silicone
  • Perfect fitment with factory airbox
  • Compatible with single stage or three stage manifold
  • Installation hardware included

This item fits the following BMWs:
2008-2013 E82 E88 BMW 128i Coupe Convertible

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
  • 11157567802, 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
