Keep the emissions plumbing flowing the right direction with the Standard Ignition Secondary Air Injection Pump Check Valve / Air Cleaner Check Valve AV18. It drops in as a direct-fit replacement for the listed applications: the 1983-1986 Ford Escort (L4-1.6L, L4-1.9L, L4-2.0L), 1983 and 1987 Ford EXP (L4-1.6L, L4-1.9L), 1985 Ford Tempo (L4-2.0L), 1983 Mercury LN7 (L4-1.6L), 1983-1986 Mercury Lynx (L4-1.6L, L4-1.9L), and 1985 Mercury Topaz (L4-2.0L).
This check valve is designed to let air from the secondary air injection pump move in a single direction into the exhaust stream while blocking hot exhaust gases from flowing back toward the pump and plumbing. If a leaking or stuck check valve is the cause of your air-injection trouble, this replaces it.
- Fluoroelastomer valve: built to withstand extreme exhaust gas temperatures to help ensure longevity.
- One-direction flow: maintains flow in a single direction for proper performance.
- 100% end-of-line tested: every unit is checked for proper flow and low-leak performance.
- Emission component quality: made with quality control maintained throughout manufacturing.
