    who's using an M20 air box?

    How do you modify it to work with M5x swaps? I thought you could use afm adapter on the box and connect tubing and then the maf, but the adapter and the AFM hole are way different sizes. Help me out, I need to get rid of the crappy cone filter I have wobbling aroumd

    You would have to have 60 amp alternator, and mod the air box mount for it to clear the alternator
