Introducing the TCE S54 individual throttle body (ITB) adaptor. This adaptor is designed to allow you to run the factory S54 ITB intake system on your S52, S50, M52, or M50 engine. Resulting in improved sound, and more power. 
 
Similar to the factory S52 intake system, our intake adaptor is made with Nylon 12 which reduces heat transfer to your intake air and the throttle body assembly. It is also easy to install, with easy-to-access stud hardware which allows you to bolt the adaptor to the head with ease. 
 
For most installations, you will need the following primary parts. 
- 1x S54 throttle body assembly
- 1x S54 manual transmission intake manifold
- 1x S54 elbow boot
- 1x BREMI 30191 MAF
- 1x S54 idle air control hoses with ICV
- 1x RRD M50/M52/S50/S52/M54 throttle cable conversion kit 
- 1x tune for ITB conversion and MAF conversion (We Recommend Kassel Motorsport)
