It said these would work on a 2001 Camaro with an LS1. It took some modifications with a dremel tool to the plugs, but they work now

Worked great on my 2008 Pontiac g8! Give you a lot slack that way your wires ain’t in a bind when you install headers!

Had to cut off one of the plastic guides and it worked. But not out of the box fit

I purchased for my Firebird ls1 and the connectors were not compatible. The connections did not fit with different spaces for the plastic grooves. I broke them to fit and they work but would not buy again for an ls1

They seem to be working great so far. I’ll update the review if something goes wrong. Otherwise it’s exactly what I needed.

Used these instead of cutting up the harness to extend my O2 sensor leads for my LS swap. Work like they are supposed to.
