Wiseco Pistons K0078XS Nitrous Top Ring Down Piston Kit Ford 4.6L 3V 3.552 Bore 8.2:1

The Wiseco Pistons K0078XS is a high-performance forged piston kit specifically engineered for nitrous oxide applications in Ford 4.6L 3-valve V8 engines. This kit features Wiseco's proven nitrous top ring down design, which positions the top compression ring lower in the piston crown to provide additional strength and durability when running nitrous systems.

Key Specifications:

• Bore size: 3.552 inches
• Compression ratio: 8.2:1
• Dome volume: -20cc (dish design)
• Deck height: 0.300 inches
• Designed for forced induction and nitrous applications
• 2618 aluminum alloy forging for maximum strength
• ArmorGlide skirt coating reduces friction and wear

Features and Benefits:

• Nitrous-specific top ring position increases piston crown strength under extreme cylinder pressures
• Lower compression ratio optimized for power-adder applications
• Forged construction handles high horsepower and detonation better than cast pistons
• Precision CNC-machined to exacting tolerances for perfect ring seal
• Complete kit includes pistons, rings, wrist pins, and locks

This piston set is ideal for builders looking to maximize reliability and performance in nitrous-injected or boosted Ford modular V8 engines. The reduced compression ratio and reinforced design provide the safety margin needed for serious power applications.
