You are viewing a brand new Yashio Factory Water Pump Pulley for the SR20 engine. The Yashio Factory Water Pump Pulley is oversized and larger than the OEM water pump pulley. The stock water pump pulley will force the water pump to spin too fast when at higher rpm times, such as drifting, and will create bubbles in the water cooling system. Bubbles in the water cooling system prevent your car from cooling to its max potential and may lead to overheating. With the Yashio Factory Water Pump Pulley, you will decrease the speed of the water pump and prevent bubbles from being created in your water cooling system. The Yashio Factory Water Pump Pulley is made of accurately cut aluminum and is covered in the signature pink color.
