Review on GM Genuine Parts Secondary Air Injection Shut-Off Valve - 21210000 by Max Guerrero

Revainrating 5 out of 5

Spare part OEM

My girlfriend's 2001 Saturn SL SOHC code was P0410. After some research, I found that this valve was most often the cause of the code that was showing, so I replaced the old one with the new one. The code went away on its own, and she also reported that the "birdsong" sound she had been hearing for a while was gone. I disassembled the old valve and found that its diaphragm was hardened and cracked. This is an OEM part so it will fit and work.

Pros
  • Country of origin: Japan
Cons
  • Expensive
