people have been using them for years, with no issues as far as I know… I only had mine on for a few weeks, but it runs great so far, even in 90° Southern California heat.Coincidentally, I saw a JLU identical to yours at my dealer today, complete with the same metal flag grill insert. The insert had tiny perforations, and I wondered about their effect on cooling air flow to the radiator.
Yeah, definitely a 10th anniversary JK. The special edition bumper and hood decals turned into a JL standard. It's hard to tell the windshield angle, but the extra bolts to fold the windshield and the slightly more spindly looking side view mirror brackets were what marked it a JK.Is that a last model year 2018 JK with a JL bumper or a JL with JK grill …..
