Genuine Scion iQ Diverter Valve

The Diverter Valve in the Scion iQ improves airflow efficiency, leading to a quicker warming of the catalyst and a smoother running experience. Renowned for its rock-solid reliability, this Diverter Valve resists heat fatigue and vacuum leaks, so owners trust it mile after mile. A heavy-duty Diverter Valve diaphragm opens and closes in concert with manifold vacuum, directing pressurized air to exhaust ports during warm up before rerouting flow when normal temperature is reached. During a rapid throttle closure the Diverter Valve vents excess pressurized air from the intake to prevent backfire and protect the oxygen sensor and cat, creating a safer environment for every Scion. Compatibility extends across the launch iQ, vibrant 1.6 liter upgrade, and diesel trims, allowing one precise unit to be utilized by the entire Scion family. Vehicle drivers experience an improved efficiency when idling, cleaner emissions from the vehicle, and a little fuel economy improvement thanks to valve timing which maintains mixtures that iQ are lean keeping the catalyst active. Thanks to the Diverter Valve's ability to manipulate airflow instead of injecting more fuel, the Scion is able to achieve its impressive 65.69 mpg, all while being quick off the line with zippy 0 to 60 times. Designed and manufactured to original factory specifications, it drops between the air pump and exhaust passage on any iQ, using simply stock hoses for quick driveway swap. The valve does not require any extra tuning. The existing vacuum lines will self-adjust the valve. Thus, steering remains playful and curb weight low, ideal for crowded streets. The Diverter Valve has a corrosion proof housing and so will keep working throughout the salty winter. This is why Scion iQ emission system is so highly rated. When a new Diverter Valve is fitted, the engineered air fuel balance is restored allowing any iQ to run clean, responsive and safe.
