I found it very easy to fit the MAF into a piece of intake plumbing incase you'd like to put your own filter on it.
I used:
-Spectre 3" O.D. - 45° Tube
-Dorman 52058 for the grommet
-Step bit for the hole, it measured to 7/10 of an inch.
MAF fits in very snug.
$23 in parts before a filter.
I've had my Maverick for 10 days now and the Android Auto is so glitchy that its literally safer to just use my phone while I drive. Multiple times I've had google maps simply end the navigation in the middle of a drive out of nowhere, and a few times even navigating to an entire different place...
