Good sensors for the money.

I'm an automotive technician. I have a 2007 Chevy Silverado Classic Z-71 4X4 5.3L Flex Fuel. Driven 600 km and no problems. The sensors are screwed in entirely by hand, a light fit with nut and ratchet, a few kilos at most, no problem. I recommend buying a new pigtail with gaskets and lubricating the gaskets with silicone before reinstalling the air intake. So far the knock sensors are working fine. I saved some money by buying these instead of Delco.
