For all those who have the M30 AFM Swap to M20 (Help!)
I have an e21 with a M20 installed. I want to fit a M30 AFM to it due to the fact that i can't have the stock airbox anyways, and it's easier to find cone filters for the M30 size.
Anyways, I have everything I need except for a substitute for the rubber boot. Are there any other solutions for this other than getting a custom piece made like Dave did in his write up that is permalinked here?
I know many of you have done this so please let me know.
