SLP Performance 12-394 Power Dome Cylinder Head Set

The SLP Performance Power Dome Head Set represents the latest advancement in SLP cylinder head technology for snowmobile performance applications. Engineered to deliver increased power output while reducing the risk of detonation, these precision-machined heads provide measurable performance gains throughout the powerband.

Performance Benefits:

• 3 horsepower increase at peak RPM
• Enhanced throttle response in the midrange
• Reduced detonation risk compared to standard heads
• Advanced dome design for optimized combustion efficiency

Important Installation Requirements:

This head set requires proper fuel management for safe operation. An SLP/DynoJet PCV Fuel Controller is mandatory to prevent engine damage. SLP provides a fuel map specifically designed for their Stage 3 kit configuration, which includes this head set along with an SLP Single Pipe Kit, SLP High Flow Intake Kit, and VForce3 Reed Valves. SLP Powder Valves can be added as an optional upgrade. Any other component combination will require custom fuel mapping, which is the customer's responsibility to develop.

Fuel Requirements:

A minimum fuel blend of 1 gallon of 108 motor octane race fuel mixed with 4 gallons of 91 octane pump fuel is required for proper operation and to prevent detonation.
