555 Engineering Dual Sensor Cooling Duct (GR Corolla)

555 Engineering Dual Sensor Cooling Duct

Keep your engine at full power and protect critical electronics on track. Channeling fresh air directly from the front bumper nostril inlet, this cooling duct prevents heat soak on high-performance builds.

• Prevents Power Pulls: Directs cool air to the manifold MAP sensor, eliminating false high Intake Air Temperature (IAT) readings that trigger the ECU to pull engine power.
• Protects Vulnerable Fuel Sensor: Safeguards the high pressure fuel rail sensor from heat-induced failure—a known wear issue discovered during 555 Engineering's GR Corolla Time Attack testing and overseas competition.
• Engine Bay Temp Proof: Printed in high-grade ASA polymer, built to withstand extreme thermal cycles, chemical exposure, and UV degradation.
  
• Motorsport-Inspired Design: Modeled after proven thermal management techniques used by Toyota endurance racing teams in Super Taikyu and the Nürburgring 24 Hour.
• Track-Tested Results: Delivers a 10–15°F reduction in sensor area temperatures during preliminary testing.
