The Supertech Block Guard for Honda K20 and K24 engines is a crucial upgrade for those looking to reinforce their engine's durability. A Block Guard fills the gap between the outside of the cylinder wall and the rest of the block, providing added rigidity to reduce flexing and prevent cracking. This enhancement is essential for high-performance engines that endure extreme stress.

Supertech Block Guards are meticulously designed and tested to support highly stressed cylinder walls and maintain optimal engine cooling. They are crafted from high-strength, corrosion-resistant 6061 aluminum alloy, ensuring long-lasting performance. Each guard is computer-designed and CNC-machined for precise fit and function, allowing adequate water flow to critical areas and avoiding destructive cylinder hot spots. Enhance your engine's reliability and performance with the Supertech Block Guard.
