Product Details

The Dorman 911-645 Secondary Air Injection Check Valve is an OE Solutions direct replacement component engineered to restore proper emissions system functionality on select Lexus and Toyota vehicles. This check valve plays a critical role in the secondary air injection system by preventing exhaust gases from flowing back into the air pump, ensuring one-way airflow that helps reduce harmful emissions during cold starts.

Key Features:

  • Direct replacement design matches the fit and function of the original equipment valve
  • Cast aluminum construction ensures reliable performance and long service life
  • Restores full functionality after original valve failure, eliminating check engine lights related to air injection system faults
  • Includes all necessary hardware and gaskets for complete installation
  • Backed by Dorman's team of product experts and over a century of automotive aftermarket experience

This secondary air injection check valve is manufactured from quality materials to meet or exceed OE specifications, providing a cost-effective alternative to dealer parts without sacrificing quality or reliability. The valve is designed to withstand the harsh underhood environment including extreme temperatures and corrosive exhaust gases.
