BMW Intake Manifold Components (DISA, Vacuum, CCV, Etc) for BMW Z3 (1996-2002)

Clear BMW chassis

Please ensure your correct model is selected

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.

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

Get the highly coveted CSL experience with your S54! Roaring induction noise, aesthetics and increased performance are just the tip of the iceberg when installing this legendary intake. Its not fair that Europe always gets the cool cars and widgets (excluding E36 LTW, thank you BMW.) The E46 CSL M3 is world renowned as one of the finest cars BMW produced. Covered with parts exclusive to the CSL model, the intake system is one of the most sought after components for non-CSL owners. The CSL intake plenum is your chance to experience the life altering CSL intake. For starters, after installation you are left with a completely transformed engine bay. You can try your very best to resist from sticking your arm in the massive inlet of the plenum but we doubt that you will be able to hold back. Turner's CSL intake plenum boasts a full carbon fiber construction with velocity stacks engineered to outflow the factory air box by over 20% and even outperforms the factory CSL air box on the flow bench because of the improved design. The CSL intake does not feature any sound dampening or silencer and allows your S54 to let out its full roar that can be heard clear through the cabin for an experience that makes you smile ear to ear. Paired with the Active Autowerke Alpha N Tune we have seen gains of up to 43 hp and 26 Ftlbs of torque in a healthy naturally aspirated S54. Performance Benefits: Airflow increased by over 20% Increased throttle response Tuning benefits far beyond the factory intake Weight reduction Roaring induction noise for both driver and spectator

The crankcase vent valve (CVV) holds and releases oil vapors that build up in the engine. It's the same type of system previously known as a PCV valve and the same deficiencies exist. Over time, the CVV will become saturated and clogged with oil. When this happens, the oil-rich vapors from the engine will back up into the intake tract and eventually into the combustion chamber. The oil added to the gasoline/air mix will cause misfires, carbon deposits, rough running, and blue smoke out the tailpipe. Replacing the CVV every 70,000 miles will ensure the correct and clean ventilation of oil vapor.

Replacement of the CVV can be done without removing the intake manifold. But replacing it during an M50 Manifold upgrade is the perfect time.

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. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

This Bav Auto oil separator helps to remove oil from the air vented from the crankcase via a hose from the valve cover. When the crankcase vent valve fails it can cause excessive oil consumption, engine fault codes, and poor idle. This crankcase vent valve is also known as the Oil separator valve or PCV. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
