Genuine Mazda CX-9 Engine Oil Drain Plug 2011-2017 CY0110404

Genuine Mazda CX-9 2011-2017 Engine Oil Drain Plug CY0110404 is an important part of the engine lubrication system, designed to seal the drain opening on the oil pan, help keep lubricating oil contained during operation, and support oil draining during routine maintenance. The plug is engineered with Mazda-standard threading and sealing surfaces to ensure it can withstand high pressure and high temperatures throughout engine operation.

On the Mazda CX-9 2011-2017, the oil drain plug works in sync with the oil pan, crush washer, oil pump, oil filter, and the entire lubrication system to maintain the oil level required by the engine. When the plug and washer are in good condition, engine oil stays fully sealed, preventing leaks and ensuring stable oil pressure.

CY0110404 is a genuine Mazda replacement part made from high-strength steel for excellent torque resistance, corrosion resistance, and heat resistance. The threads are precision-machined, and the sealing washer helps improve oil leak prevention while allowing repeated removal and installation during servicing. The product is manufactured to the correct specifications and fits the Mazda CX-9 2011-2017 without modification.

After many oil changes or improper tightening, the drain plug may suffer thread wear, a deformed plug head, or damage to the sealing surface. The sealing washer may also become crushed or lose elasticity, leading to oil leaks at the bottom of the oil pan. If not replaced in time, the engine may lose lubricating oil, affecting lubrication performance and increasing the risk of wear to internal engine components.

CY0110404 is manufactured to genuine Mazda standards, delivering high durability, optimal sealing performance, and full compatibility with the Mazda CX-9 2011-2017.
