Review on 🔧 Enhance Engine Performance with GM Genuine Parts 219-505 Secondary Air Injection Pump Kit by Carlos Alston

Fast delivery. The details seem fine. The mechanic chose not to install/replace all of the wiring and hoses included in the kit. He saved time while I spent money on the purchase. After 2 weeks of driving, the air pump has still not passed the inspection. Driven 50 km and the service engine light came on again. This was diagnosed due to a faulty relay switch (not included). I'm not happy with the mechanics, but I can't fault the parts.
