Delphi AS10017 Ignition Knock Sensor

07 Sierra 1500 classic w/4.8. These work perfect! Finally fixed my low power issue. Delphi makes most of GMs electronics so these were a no brainer.I did not have an CEL at the time but always suspected the stock ones were on their way out. They were just overly sensitive. I had no power under full throttle until the RPMs came up around 3K. Now this is like a new truck again!

good quality

Funciono correctamente.

الأصلية دامت في الخدمة مدة ٢١ عاماًوأما هذه دامت سنتين فقط !!الجودة في منتجات ديلفي تغيرت أصبحت سيئة جداًبعد ما كانت القطع الأصلية هي ديلفي لسيارات جنرال موتورز

I used two of these sensors, along with a relocation blocks and harness to fix knock sensor codes on my 2005 Silverado 4x4 5.3 You will need a stubby 22m socket to tighten knock sensors to 15 foot/pounds if you mount them on the front side of the relocation blocks, due to limited space. I did not have a stubby socket, so I had to grind an old 22 mm socket to be able to use a torque wrench to apply the right amount of torque.
