Review on 🚗 High-Quality Dual Knock Sensors with Wiring Harness Kit for GM Vehicles - Replace # 12601822 12589867 917-033 by Keith Harris

Exchanged a known good engine for my Silverado. Engine without codes. As a precaution, I changed the knock sensors and the wiring harness because the engine is used. I know they are under the intake manifold and were easier to replace when changing the engine. The knock codes have been there since the engine change and I don't have enough motivation to change them. So life is! I would not buy these. Buyer Warning. Buy genuine Delco Air Conditioning Knock Sensors and save yourself the headache.
