Supertech Performance BG-B16 Block Guard High Strength Aluminum

The Supertech Performance BG-B16 Block Guard provides critical reinforcement for highly stressed cylinder walls in performance and racing engines. This precision-engineered component helps prevent cylinder wall distortion under extreme boost and high horsepower conditions while maintaining optimal coolant flow to prevent destructive hot spots.

Key Features:

• Manufactured from high-strength 6061-T6 aluminum alloy for maximum durability and corrosion resistance
• CNC machined to precise tolerances for accurate fitment and proper installation
• Strategically designed coolant passages maintain water flow in critical areas to prevent cylinder overheating
• Reinforces cylinder walls against distortion from high cylinder pressures and temperatures
• Ideal for turbocharged, supercharged, and high-compression naturally aspirated builds

Block guards are essential components for engines operating under sustained high loads, preventing cylinder wall flex that can lead to head gasket failure and cylinder bore distortion. The BG-B16 has been extensively tested and validated in demanding racing applications.
