Blox Racing Block Guard Honda H-series

BLOX Racing engine block guards help strengthen and support the upper cylinders walls in open-deck Honda/Acura engines.
CNC-machined from AL6061, the BLOX Racing engine block guard also provides maximum coolant passage to the head minimizing the risk of head gasket failure and cracked cylinder sleeves.
At high RPMs block guard reduces cylinder wall flex. This prolongs a stronger and longer lasting engine.
Manufactured of the highest quality aircarft grade aluminum, the block guard presses into the block sleeve for an easy install.

Application : Blox Racing block guard provides protection for your turbo / nitrous / high performance all motor application if it is not necessary to sleeve your block.
