Put in a Rotofab CAI today (the "no tune" one which I bought from another member here, but not until after buying $120 in hardware after he said "yeah it's all there"; thank goodness Rotofab has awesome CS).
I'd say it bumped up the s/c whine from about a 3 to a 5 in volume. Good enough for me for now.
Quick check on the s/c noise...
Figured while I was there I would yank out the rain / snow deflector. Wow, what a pain getting that out... I literally did end up yanking out the last (bottom) connector. Getting the bolts on the hood latch isn't too much fun when you have sausage fingers with XL hands. Ratcheting wrench helps a ton. (1/2" btw)
Put in the Diode Dynamics smoked LED side markers. Nice little upgrade, like the contrast.
Moved my Uniden R7 over to the left about an inch so I can see the arrows, and installed a dash cam, Viofo A139 Pro 4k to the right of it. (Vid above)
