Review on 4 Pack Red CKAuto USA Flag Valve Stem Caps - Aluminum, Dust Proof & Corrosion Resistant For Cars, Trucks, Bikes & More! by Ronald Howlett
Best nitrogen caps.
Costco fills tires purchased there with nitrogen. These caps look great and are a good reminder to use only nitrogen to fill our Michelin tires. They are simple but look great. I can strongly recommend these caps.
Pros
- Color is as pictured and looks good on my vehicle
Cons
- They may not have a very tight seal
