Genuine Scion FR-S Air Inject Check Valve

The Scion FR-S Air Inject Check Valve protects the coupe with the clean one-way airflow that cuts harmful exhaust gases and maintains sharp throttle response. Constructed to factory standards, this Air Inject Check Valve is known for its long-term reliability, allowing all Scion owners to use their full power without concerns of premature failure. Its robust housing can safely withstand heat and vibration when running hard FR-S, and its internal seal has a quick response, opening only when fresh air is required and closing to prevent reverse flow that can damage emission plumbing. Since the part is applied in the same standard form in all years, it can be applied in the early launch FR-S models and in later refreshes, making it an easy hassle-free replacement for any Scion fan who wants maximum efficiency. The Air Inject Check Valve accelerates hydrocarbon burn-off by gradually feeding secondary air to the catalytic converter, preventing the sensors of the nimble Scion coupe from being impacted by hot blowback. This is an active defense of tailpipe emissions and contributes to modest fuel economy improvements, which means spirited FR-S commutes are cleaner and more wallet-friendly. Another feature is its self-contained, maintenance-free design, meaning that the Air Inject Check Valve is self-powered without control modules or vacuum lines, a feature that makes it very simple and increases its overall durability. Owners laud the ease of the real Scion part fitting with factory gaskets and instantly recovering the crisp cold start idle that is synonymous with the FR-S experience, as the Air Inject Check Valve is a small but extremely important watchdog of performance and safety. The replacement of the Air Inject Check Valve at the prescribed time intervals keeps all Scion FR-S in compliance with emission regulations and prepared for the next winding back road. That established Air Inject Check Valve tradition assures drivers mile after mile.
