Get all of the benefits of the legendary BMW M50 intake manifold on your E46, without the hassle. Retain the ability to revert to the M54 manifold if needed. Designed and manufactured in the USA, this kit spares no cost and uses only quality materials.
Check our blog for more installation information and our experience with the intake!
Replacing the M52TU/M54 intake manifold with the M50 intake has many benefits, including:
- Increase in power- About 20hp N/A depending on application
- More flow at high RPM, for an extended powerband
- Better throttle response
- More engine bay room
- More injector options
- Removes the DISA valve, which often fail and only functions in slow city driving, not performance environments
Our kit includes a throttle body adapter plate and hardware to use your M54 electronic throttle body on the M50 manifold, templates to quickly and easily port match the intake if you like and inserts to plug the ICV ports on the head without any need to remove the head or use special tools. Fits both 2.5L and 3.0L throttle bodies. If you have a M52TU, your cable driven throttle body will bolt right up without this adapter, you can order the plugs and templates separately in another listing.
Add our silicone hose kit with motorsports grade materials ready to handle any level of boost. Also great for a clean install on any vehicle. Includes all hoses required to install your original ICV.
Add the billet ICV fitting. The stock fitting is plastic and brittle- Not good for boost or ihgh engine bay temps! This one will stay in place no matter what- increased reliability and bling!
The billet fuel rail is a real motorsports grade setup that handles any pressure and flow. Doesnt hurt that it also looks great as well. Great for pass through fuel systems and using an aftermarket fuel regulator.
Injector Spacer kit recommended for aftermarket injectors. These spacers are sometimes required on aftermarket slim body injectors so they don't push too far down into the intake manifold and create a vacuum or boost leak.in the future.
If you have any questions or need any of these products separate, send us a message via email or instagram and we'll respond asap.
