The 1999-2003 7.3L Power Stroke uses an intake air heater element in the Y-bridge that warms incoming air to reduce white smoke during cold idle. When it stops working, you'll usually notice:

• Excess white smoke at cold idle that lingers before the engine warms
• Rougher running in the first minutes after a cold start
• Slower, smokier warm-up in cold weather

The genuine Motorcraft F81Z-9N424-BA is a direct-fit replacement built to Ford specifications, and it installs in minutes with no special tools. Keep in mind the intake heater is not a starting aid, the glow plug system handles cold starts, its job is reducing cold-idle white smoke and smoothing warm-up.
