Supertech Block Guard for Honda B16A/B18C

Made from solid 6061-T6 aluminum, this block guard is designed to reinforce the cylinder walls of your Honda B16A or B18C engine. It sits between the cylinder sleeves, adding structural integrity to the block, especially in the areas most prone to distortion under high pressure.

When you're pushing significant boost or planning a high-performance build, the stock block can sometimes flex. This guard helps prevent that flexing, keeping your cylinder bores round and true. It's a well-built piece that adds a crucial layer of strength where it's needed most, helping to maintain proper ring seal and prevent costly engine damage.

Installation involves removing the engine block, cleaning the deck surface, and then installing the guard. It's a common modification for boosted B-series engines, offering peace of mind for serious builds.
