The AC Autotechnic Block Guard, also known as a sleeve saver, is a special cnc machined aluminum brace that fits into your open deck Honda B Series engine and prevents the cylinder sleeve from flexing during high RPM, nitrous or high boost applications. AC Autotechnic, through their research and development along with race history, has designed a superior block guard sleeve saver that almost eliminates engine sleeve flex. The trick is to have a block guard that is strong enough to prevent flex in the sleeves, but also has properly positioned watering holes that allow your water and coolant to flow in the open deck design, and ensuring your engine continues to run cool. Perfect for the enthusiast who wants to take the added protection in using a block guard sleeve saver on their B16 or B18 Honda engine.
