Relays are essential to any electrical system, helping to protect otherwise vulnerable circuits from current overloads. The emission control system in your vehicle depends on these little dynamos just the same, utilizing them in everything from fuel evaporation functions to diesel light controls. When you've got a power outage to resolve, find the replacement relays you need at StockWiseAuto.com today.

Oftentimes, a bright red Check Engine light is your first warning of trouble within the emission control system. If you're getting reduced performance when you drive, check for the diagnostic trouble code; readings such as P0418 relate to components such as the secondary air injection relay. StockWiseAuto.com has this part and plenty more to keep your vehicle emissions in check every day.
