Ooops...don't mean to be so far out of my geographic area...but I saw the post

That K&N filter is probably the most popular on this site (#3530) and will flow enough air for a lot of mods. The MAF adapter looks good to go. The little moutning bracket is a nice touch, as it'll keep your AF from "sagging" down and toward your battery. But if you drive in a lot of hot weather, you'll still get heatsoak unless you build a heat sheild. But $100 is a little pricey.
A MAF adapter can be had for $26 shipped from duratechperformance.com, and the K&N can be had for $35 shipped from Jegs.
So is the colored MAF adapter and that bracket worth $49? Might be to you...but performance wise...its a solid set-up.
