(1) Roll of Aluminum foil High-temp tape





Here is a quick installation summary (pictures shown are of E39 M5 installation):

1. Remove top portion of OEM airbox




2. Remove the air intake guide that's snapped on







3. Cut the bent 15" pipe by 6.5" at both ends.


4. Apply Aluminum foil tape on one end of the bent pipe and test fit along the way... Continue until it fits tightly enough...









5. Connect the AEM filter to the end of the pipe.






6. Verify that the airbox lid closes well without any extra force...





This custom CAI on the M5 will give you a gain of 12HP as per Dyno...
