missing factory notch in factory caps

The original cap has a notch for connecting the vacuum line, this cap lacks this notch rendering it unusable. The OEM fitting is non-removable, and since it's a vacuum line, you don't want leaks or bled air in the inlet. It's a design flaw and all should be withdrawn. The spring seems fine and the silicone membrane is fine. My mechanics at Arlington Auto Tire in Pok showed me the differences and now when you see them in person it's obvious but you don't know by looking at these photos.

Pros
  • Excellent construction
Cons
  • Protection
