My 2016 Honda CR-V EX came stock. I added:
1) Weather-Tech front mats,
2) VLED interior bulbs (made a huge difference in the inside lighting at night and VLED brand have passive aluminum heat sinks so they last extremely long), (I had bought interior LED's from a company called Precision LED and they kept burning out),
3) an Apex high output alternator rated at 200 Amps at idle and 350 amps at a faster engine RPM (tested before shipping to me at 188 Amps at idle) and I had to put a shorter serpentine belt on the vehicle because this high output alternator has a smaller pulley on it so it spins faster,
4) upgraded the battery from 51R to 24F Walmart MAXX including bigger battery tray and heat shield, scraped away paint under body panel where the ground wire from the battery bolts down, scrape copper ground lug clean where it mounts and put Corrosion X Aviation on all connectors for battery,
5) 0-gauge wire from battery + to alternator output, 0-gauge wire from battery ground to engine mount ground by alternator, and 0-gauge wire from alternator to a 250 Amp low voltage fuse, and then through the fire wall, then ran beside passenger's door, coming out of floor under front passenger's seat terminating in a high current quick-connect,
6) a Mean-Well 2200 Watt 4400 Watt Peek very high reliability pure sine wave output with over-load damage protection inverter with 0 gauge wire and a quick-connect that mates with the one under the front seat, and now have Velcro on the bottom of inverter so it sticks to the floor behind the passenger's front seat, installed a hole with rubber grommet around it big enough for a 12 gauge outdoor extension cord to come up under the vehicle to connect to the inverter, and a cap on that hole when not in use,
7) had a vehicle upholstery shop add more heater elements to the driver's seat so than now I can turn on heat for the entire height of the back of the driver's seat for my bad upper back, and a switch so I can independently turn off the heated bottom of the driver's seat when I want a lot of heat for my back but do not want to cook my tail end.
8) got tired of hitting my head on the side of the back hatch, so I got support struts that open 2.16 inches more but still close to the same length from Lift Support Depo, and had a body shop roll back the upper lip of the back hatch so it does not hit the roof when the new longer struts cause the back hatch to open MUCH higher, 2.16 inches more at the mount point of the struts that is close to the hinge makes the end for the hatch that is far from the hinge open a LOT higher. NOT MORE HITTING MY HEAD, even when stepping off a high curb beside the vehicle by the open hatch.
9) I also had the vehicle spray under coated at a company that has a package deal that I bring it back every fall for 6 more touch-ups.
10) I got software for music and put together a collection of about 2000 songs of the type of music I like and put that on a flash drive that I keep in a USB port in the vehicle so I can play my music when I am using the vehicle.
11) Fumoto oil drain valve.
12) Did 3 drain and fills of the CVT with Honda fluid with about 1000 miles driving between each change to mix old with new.
13) Disassemble and lube front and back brakes, flush brake fluid with Bosch ES16 Brake fluid.
14) Added a club and an alarm that sounds inside my house if someone enters the vehicle.
