Hi all, I've been looking to purchase the
Rev motoring boot for my n52 z4 but while cleaning my airbox I noticed the 328 n52 intake is different than ours:
Ours has a tube going to the "sound conducting medium" bottom diagram vs top

Has anyone installed the boot? Is it okay to just leave that part opened?
Thanks
