Supertech Block Guard for Honda D15B/D16Z/D16Y Single Cam

This is a Supertech block guard for Honda D15B, D16Z, and D16Y single cam engines. It's designed to reinforce the cylinder walls of your engine block, especially important if you're planning on increasing boost pressure or making more power than stock. By adding this support, you help prevent the cylinder walls from flexing or distorting under increased load, which can lead to blown head gaskets or other serious engine damage.

The block guard is made from solid aluminum and fits between the cylinder sleeves. Installation involves removing the engine block, cleaning it thoroughly, and then installing the guard. It's a common modification for tuners looking to build a more robust engine for boosted applications. This part is a well-built piece that adds a significant layer of protection to your engine's critical lower end.
