Trap and hold evaporating fuel-tank vapors instead of letting them vent to the atmosphere with the Standard Ignition Vapor Canister CP437 — the charcoal canister at the heart of your evaporative emission (EVAP) system. It installs as a direct-fit replacement for the 1999-2004 Ford Mustang, 1999-2002 Ford Ranger, 2001-2003 Mazda B2300, 1998-2001 Mazda B2500, and the 1998-2004 Mazda B3000 and B4000; see the Buyer's Guide tab for engine-level fitment.
The canister collects fuel vapor from the tank in its activated charcoal and, on command from the purge system, routes it into the intake to be burned during normal combustion.
- Direct-fit OE replacement: OE-matched connector and terminals for correct performance and easy installation.
- Durable housing: designed to withstand temperature fluctuations and exposure to chemicals and debris.
- Higher-mileage focus: specially engineered for higher-mileage Ford and Mazda vehicles.
- Validated function: undergoes extensive lab and on-vehicle testing so the complex EVAP system operates as the OE intended.
Common signs this part may need replacing include a fuel-vapor odor, an EVAP-related check engine light, or trouble refueling. If a saturated or cracked canister is the cause, replacing it with the CP437 addresses that component; diagnose the EVAP fault first, since other parts can trigger the same symptoms.
