XTREME Big Bore & High Compression Piston Kits (PAGE #2)
WARNING
When installing any High Compression Piston you must check the piston to valve clearance in the final assembly of your engine. You should have AT LEAST 1.0MM of clearance between the valves and the piston crown as the engine is rotated.
Using a big bore, high compression piston will require you to run premium or race grade fuel to prevent detonation (spark knock) and severe engine damage.
High Compression engines should use Oil coolers to help control engine temperatures.
