Your stock air box is sealed against under-hood hot air. You can open up the fender opening of that box for more air intake for free. The box-to-manifold tube can be replaced with an AirAid MIT and a dry replacement filter for smoother air flow and some "growl", if that's your thing. Oiled filters may mess up your MAF.

Mod 'em! Listings never take that into consideration. They manufacture for the mass sale.

I've often wondered what those doofusses were doing in the Walmart parking lot. Now I know.

Here's an interesting site that may be helpful: http://www.oilfilter-crossreference.com/

Lund and Auto Vent Shade are corporate "brothers", so the products may interchange. One hint on any brand of in-channel visors: replace the factory "sticky tape" with 3M molding /weatherstripping double-sided tape, clean the truck's window moldings where they are to contact the visors REALLY well with alcohol (90% rather than 70% because of glycerin content), and bevel the edges of the visors where they contact the glass. Install the visors and shim between glass and visor for a FIRM contact. Leave 'the windows up for a good 24 hrs. or longer, and you might end up with a trouble-free installation.

I used this set-up on my '13 and am very satisfied with the results. Easy, plenty of light, and very economical. https://www.instructables.com/id/10-12-Truck-Bed-LEDs/
