Product Details

The Holley EFI 300-251 MAP Sensor Port Cover is a precision-engineered billet aluminum plug designed to seal unused MAP sensor ports on LS3-style intake manifolds. This professional-grade component provides a clean, reliable solution when converting to an alternate sensor configuration or blocking off an unused port.

Key Features:

  • LS3-style plug design for direct fitment
  • CNC-machined billet aluminum construction for durability and corrosion resistance
  • Includes O-ring seal for leak-free performance
  • Complete with all necessary mounting hardware for easy installation
  • Compatible with most intake manifolds featuring LS3-style MAP sensor ports

This port cover is ideal for custom EFI conversions, standalone engine management systems, or any application where the factory MAP sensor location is not being utilized. The included O-ring ensures a vacuum-tight seal, while the billet aluminum construction provides a professional appearance and long-lasting reliability.
