Hello from Canada
Just bought a black 2017 trailhawk last week, it's my first jeep and the newest car i've owned so far and i'm liking it.
The previous owner installed a k&n cold air intake and a pedal commander p4. The k&n add a nice engine grunt a bit round on higher rpm. The pedal commander is amazing, put it in sport+ and the accelerator is super sensitive and responsive. I would recommend everybody to install one.
On another note, I feel like i'm not getting a lot of range from a full tank, I filled twice but haven't gone to empty yet but at half tank I've got both times around 190 km's I don't know if thats what everyone is getting or the k&n and the pedal commander has lowered my range, I've had a mix of driving styles within that period of time, sometimes with the pedal commander off, and sometimes driving slow. My average mpg on the trip info screen is 12.5 L/100km.
Firsts upgrades I would like to do is a lift kit, some beefier all terrain tires and wheel spacers, at least on the rear, I feel like the rear tires look way to far in compared to the body.
