N52 Manifold Upgrade Lite Kit - E90 325i -10/05

Product Description

This 330i manifold installation kit is the most basic parts that are likely needed when installing the 330i N52 intake manifold on your early E90 325i (cars made before 10/2005 production date). Other kits will have a lot of other parts that may not be necessary and just add expense. The Lite Kit includes:

• 11617522933, OEM Rein crankcase vent hose. This has a very fragile plastic connector that will likely break off your original manifold. Even if it comes off clean it's a good idea to replace the hose anyway as they clog with oil residue.
• 11617547242, OEM Elring manifold gasket set

Important Recall Information: the 90° angle connector on the underside of the manifold is a crankcase vent heater (aka "blow-by heater"). It's part of a factory BMW recall campaign due to a risk of fire. When buying a used manifold it may come with the original defective connector. Hopefully your original heater has already been replaced under this recall so you can transfer it to your new manifold. We can also supply you with the new BMW version of this part (see link below) or you can ask your BMW dealer if they will replace it for you before installing your 330i manifold.

If you're buying a used intake manifold there are a few items that should be replaced but you probably don't need a complete overhaul. You may not need the DISA valves if the manifold comes with them but you should definitely remove them for inspection. Make sure the frame and flap mechanism are not broken and that the seal around each DISA is not damaged (the seal is not available separately from BMW). Test the flaps ahead of time to ensure they move all the way open or closed (check YouTube for test videos). The screws from the DISA valve can be re-used (or buy new ones from the links below).

These are OEM manifold parts manufactured by the original suppliers to BMW for these parts. As OEMs they meet all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. These parts have a two year warranty.
