Review on π Set of 20 Chrome Plated Brass Tire Valve Stem Caps with N2 Nitrogen Sign Logo - Dustproof Valve Covers for Car Auto Tires by John Blanco
Good caps for nitrogen valves
Good for identifying nitrogen filled tires. Most new and expensive vehicles are filled with nitrogen instead of air to minimize psi expansion and fluctuations. This cap notifies service technicians when a nitrogen fill is required.
Pros
- Very fast delivery
Cons
- Slightly torn
