Full disclosure - I do have a set of APEX valves on one of my sets of tires and they are pretty sweet. Very similar to the Monster Valves. I was a little leery of them for a while but they seem to be holding up well. (I have a spare set in case I ever have an issue with one or more)I had money burning a hole in my pocket so I installed the Powertank "Power valves", in now way are they necessary but they sure do make airing up and down faster. Another benefit is when airing up at the trailhead I hook the compressor to one valve stem and clip a gauge on the other, I'm able to keep an eye on the pressure while I complete other tasks like cleaning the windshield and tying things down before I get on the highway.
I noticed the valve stems on the JL's with the TPMS sensors have 2 tiny holes drilled on the sides for air to pass through. The small holes don't make much difference when airing up with a 12v pump, but when filling tires at home with my big 220v shop compressor it seemed to take forever squatted next to the jeep for several minutes per tire.
Apex valves are really fast .. but they are fairly tall and depending on your wheels, if they aren't protected they are prone to being snapped off by rocks and branches. I ran Hutchinsons for a while and they are shallow and the valve stem isn't very well protected. I snapped one Apex valve off in the middle of the Rubicon. Fun times breaking down the beadlock at camp to replace it; thankfully I had a spare valve. I would definitely run them again if I had deeper wheels.I do have a set of APEX valves
