Intake horn and resonator delete.
I finally got around to replacing my tensioner roller before Sandy came with the rain.
As I was buttoning her back up, I noticed a tear in the MAF boot. That's when I decided to go ahead and do the horn and resonator delete. After some searching, I discovered that all I needed was a MAF boot from an E46 323 (p/n 13541705209). This boot is also almost $20 cheaper from the dealer vs. the one with the hole for the resonator box.
