Intake Manifold Upgrades & Components (DISA, Vacuum, CCV

BMW Intake Manifold Components (DISA, Vacuum, CCV, Etc) for BMW 3 Series E90 (2006-2011)

The intake manifold takes incoming air from the intake and distributes it to each cylinder. Over the years the manifolds have gotten more sophisticated and complex. Most of the additional work that it does is emissions-related - recirculating vapors back into the engine to be re-used. But there are also performance innovations such as BMW's DISA variable intake runners. All of the modern innovations have a part behind it and here you will find replacement components.

In some BMW models there are performance improvements with intake manifolds. These intake manifold upgrades use mostly BMW parts and are a direct replacement for your stock manifold. We offer manifolds and kits to make the conversion work easier.

The E90 330i had the highest horsepower out of the N52-powered vehicles. The reason for this was while the 128i, 325i, 328i, 525i, and 528i received a single-stage manifold, the 330i was gifted a 3-stage manifold. A 3-stage manifold consisted of 2 DISA valves that would divert air to the cylinders that needed it. With more air going to the appropriate cylinders and fuel adjustments by the ECU, this valve system helps extract the most power from the N52. Luckily this amazing manifold bolts on to any version of the N52 and, after a flash of the ECU, can give you up to 42hp! *Flash Software not currently available from ECS Tuning* Kit includes: 330i intake manifold Both DISA valves Gaskets Mounting hardware Crankcase vent hose

Introducing the E9X M3 Carbon Fiber Plenum from Eventuri. Made from 100% high-grade prepreg carbon, including the internal trumpets, this plenum replaces the stock plastic version and unleashes the roar of the naturally aspirated BMW V8 engine. Since the trumpet lengths are tuned by BMW to the internal volume, changing this could result in a loss of performance, so Eventuri kept the same volume to not upset the way the car drives in terms of power delivery. Although there isn’t a performance gain from the carbon plenum, the induction sound generated takes the driving experience of the M3 to a whole new level. The raw V8 rumble gives the M3 an almost CSL like sound and is a truly intoxicating experience. Eventuri went through several iterations using different carbon thicknesses to fine-tune the sound, and the resulting plenum generates an almost unbelievable induction volume and tone.

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
