HOLLEY MID-RISE INTAKE MANIFOLD LS1/LS2/LS6 CATHEDRAL PORT HEADS 105MM THROTTLE BODY

Features:

• Provides great performance to 6500 rpm for street/strip performance applications while providing the look of a racing EFI intake manifold
• Unique modular design allows the combination of a traditional dual-plane layout with an EFI manifold plenum to produce great mid-range torque without compromising top end power
• Great for supercharged or turbocharged engines
• Power band from 1500-6500 rpm
• May require an aftermarket hood for some vehicle applications.
• Cast aluminum construction
• Intended for use on all GM LS Gen III or IV engines equipped with LS1/LS2/LS6 style cathedral port cylinder heads (recalibration of the ECU may be required when using this intake manifold design with OE ECU).
• 105MM EFI plenum top

NOTE: Recalibration of the ECU may be required when using this intake manifold design with OE ECU.

NOTE: Holley EFI LS main harnesses have a map sensor connecter designed for use with an LS3 style map sensor. Adapter harness may be required to adapt any LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which is recommended for this manifold.

NOTE: These manifolds & fuel rails are designed to accept Bosch Style EV-1 or Magneti Marelli Pico fuel injectors (OE LS fuel injectors may not fit properly in the intake manifold & fuel rail assembly).
