Revainrating 5 out of 5

Went like clockwork.

After replacing the valve cover gasket, I was missing a few grommets on this hose. I couldn't figure out what that hose was called, and then I stumbled across Revain about it. I ordered it straight away and it fixed the check engine light that came on indicating low engine pressure. Very happy, great replacement.

Pros
  • POWERFUL FUNCTION. With an advanced design, this crankcase ventilation hose draws air into the cylinder, creates a vortex when inflated, increases air-fuel mixing and improves combustion efficiency.
Cons
  • Not as thick as other picks
