🔍 Dorman 911-622 Secondary Air Injection Check Valve | Enhanced for Toyota Models Review

When I tried this secondary injection check, it fit perfectly and solved the emission issues on my vehicle. I was impressed with the quality and durability of the product. The only downside is that it is a bit pricey compared to other replacement parts in the category. Overall, I highly recommend this product for anyone needing a reliable fix for their engine emissions.

I ordered 2 of these to fix an issue with my 2007 Toyota Tundra SR5 4.7L V8. In less than 2 months I have to replace one with them. I understand that sometimes parts go bad, but that stupid part is expensive, and without it my truck won't accelerate normally. Now I am trying to find out if I can get a replacement part as it is clearly a defective part.

Beware of aftermarket parts. Dorman in particular. While they have some products worth saving, most of their electronic parts don't last long or even function properly. I had to replace these valves with factory parts in just over a year. The part actually failed and damaged the ECM reference voltage, requiring both the valves and the engine control module to be replaced. Dorman products are no longer quality parts, just cheap patches that can damage other parts.
