Review on GM Genuine Parts Secondary Air Injection Shut-Off Valve - 21210000 by Fernando Hudson

My stepdaughter's 2001 Saturn failed an emissions test with DTC P0410: Secondary Air Injection System. I never thought I could fix it to make it go through. However, I went to You Tube and watched the diagnostic video and found that the non-working part was this bleed/check valve. I bought the part from Revain; installs it. After the next driving cycle, the vehicle has passed the emissions test. I couldn't get this part at my local parts store so I bought it from Revain, especially after checking the cost at my local GM dealer.
