Review on AEM 20 403S Air Bypass Valve by Charles Parente

Revainrating 2 out of 5

Cannot conform to almost all bumps, cracks and leaks.

Cannot adapt to shock, breaks and leaks almost immediately. Plan to trim the air intake closer to the body from the front so you don't have to worry about an alternate intake.

Pros
  • To see which bypass valve is right for your cold air intake system, visit the AEM Electronics website.
Cons
  • Operating speed
