Review on FV246 Positive Crankcase Ventilation Valve by James Mangum

Revainrating 3 out of 5

Worst Ventilation Valve Ever

When I tried this product, it did not make any significant change in my car's emission. IN fact, it gave me more headaches than before. This is the worst ventilation valve Ive ever purchased..

Pros
  • None
Cons
  • Did not improve emission, caused more problems.
