Ok i know its one of those topic which everyone says sleeve it.
well i know some bad things about block guards are they dont allow much cooling and expanison of stock sleeves.

SO whats your import on the race engineering block guard.

I has the little vents to provide more cooling that the conventional block guards. more cooling means the sleeve shouldnt be expanding to much. so is this block guard a bit safer than the others
