I think I'm gonna do it lol.
I still need to research what I need to do for my '17, I think MAF extender, then this dealie

Update: ordered. Will have it mid-march. I got the JST plug and play MAF harness, since its plug and play I am going out on a limb and assuming that means no cutting. I'll order the cobb doohickey when it's closer to "time". Shipping was surprisingly expensive.
I also need to find a part number for the stock cowl to have on hand.
