Detailed Description

Gates EMH054 is an emission control hose designed as an OE-exact replacement for the crankcase ventilation path from the valve cover to the intake tube. It is engineered for Toyota Corolla, Toyota Prius, Toyota Prius AWD-e, Toyota Prius Prime, and Toyota Prius V applications where the original hose has aged, cracked, or lost sealing integrity. This part cross-references Standard Ignition V804 for the same application. Gates EMH054 is built to match factory-style dimensions and connection style, helping maintain proper airflow and vapor routing in the emission system.

Installation Notes and Tips

Confirm the hose routing matches the original valve cover-to-intake tube path before installation. Inspect the mating ports for debris, oil residue, or damage so the push-in ends seat fully. Compare the original hose length and bend profile to the Gates EMH054 before final assembly.
