The first valve, part number 86-87-89-90-138200-0120A, is responsible for controlling the idle air flow in your engine. It works in conjunction with the engine's Idle Air Control System (IAC) to ensure a smooth and consistent engine idle, even under varying load conditions. The thermostatic design of this valve allows it to adjust the bypass flow based on engine temperature, thus helping to maintain optimal fuel economy and emissions.
The second valve, part number 86-87-89-90-138200-0120B, serves a similar function but is specifically designed for use with Honda engines, which were often used in early Acura Legends. This valve also controls the bypass air flow to the engine, but it uses a different temperature sensitivity curve to account for the differences in Honda engine designs.
Both valves in this set are made from high-quality materials to ensure durability and long-lasting performance. They are designed to fit seamlessly into your existing engine system, requiring no modifications to your vehicle.
Installing these thermostatic bypass valves is a straightforward process that can be done by most DIY enthusiasts with basic automotive tools. However, if you're not confident in your abilities, it's always a good idea to consult a professional mechanic.
