Review on 🚗 High-Quality Engine Knock Sensor Wire Harness Kit - Replaces OEM 12601822, 917-033 - Compatible with Chevy, GMC, Cadillac - Suburban, Silverado, Avalanche, Tahoe Sierra, Yukon, 4.8, 5.3, 6.0 by Jeffery Pricinoc

I changed the oil pressure sensor and decided to swap out the knock sensors while I was there and it's a great suspension. I'm not afraid of water getting under it and no, I didn't seal the knock sensors on the RTV. You don't have to do this unless you're using foam pads under the intake manifold (although you should, as that's their purpose). I have driven many kilometers with it and it is perfect, no problems and it fits like the original. Great purchase, great item!
