Looked around quite a bit for these ACDELCO knock sensors at this great price. I did find lower priced ones but were not OEM. It's a shame these are not on a recall since many people tend to have the problem of watering entering the space where sensors are located ruining them on our 2003 Chevy Tahoe. Only the rear sensor looked bad but went a head and replaced both along with cables from Dorman and new intake manifold gaskets. The original gaskets looked new at 100K miles but replaced anyway since it's a couple of hours a work to do this job.
