Supertech Block Guard for Honda K20

Supertech is known for making well-built valvetrain components, and this block guard for Honda K20 engines is no different. If you're pushing your K20 hard, especially with forced induction or high boost, this part helps reinforce the cylinder walls. It's designed to prevent the walls from flexing or distorting under extreme pressure, which can lead to blown head gaskets or worse.

This block guard is made from solid aluminum and fits snugly between the cylinder sleeves. It adds rigidity to the block's deck surface, giving you more confidence when you turn up the boost. It's a popular choice for K20 builds that need that extra layer of protection for the engine block.
