The New Holland 47364243 is an original equipment manufacturer (OEM) AdBlue filter designed to maintain the purity of the Diesel Exhaust Fluid (DEF) system in New Holland T4B series agricultural tractors. This critical component prevents contaminants from entering the selective catalytic reduction (SCR) system, ensuring efficient operation and compliance with emission standards. Regular replacement with a genuine New Holland 47364243 filter is essential for the longevity and performance of the AdBlue injection system.
