Fit For KEWS K23 NB300CC Dirt Bike Motorcycle Radiator Tank. The presence of an intercooler effectively prevents engine knocking or detonation, which safeguards critical internal components from potential damage under high boost. It allows the turbocharger to operate at higher boost pressures safely, thereby unlocking greater potential power output from the engine. Air-cooled units boast a simple structural design and easy maintenance, fitting for situations where vehicles often operate at high speeds. Water-cooled configurations provide steady cooling that isn't affected by vehicle speed, ideal for regular commuting in urban areas., Manufacturer: AKPOUYC
