BMW M5 intake installation
So I finally have some time to start working on my M5 factory intake retrofit this weekend.
I realize there are a few aftermarket choices, but I'm trying to keep the engine bay factory looking while possibly getting some performance out of the air intake system. I believe the factory M5 intake system should yield some increased air flow due to the less restrictive pipe design. There is a thread below of a guy doing a custom setup with chevy MAF adapter, which brings me to my question.. Can I use the M5 MAF sensors, since the mounting points for my N63TU MAF's are different then the intake hoses from the M5? I have a stage 1 BM3 tune, was just worried about installing the MAF from a slightly different engine management system. Anyone have any thoughts on combability? |

I don't believe the M5 has MAF sensors. So there is no compatibility.
The S63/TU removed the MAF sensors and used a different method to derive airflow. BMW realized that MAF sensors reduce airflow by about 28% (from memory). So they derived MAF by other means. Which means a tune for you to run MAFless or retrofit in the N63TU MAF sensors with some tubing or something else. |

It has maf in the air intake housing pipe, just like my n63TU, the plug is the same and all but I don’t know if software wise in DME it’s not utilized.. if it isn’t then I should be ok then.
