Genuine Holden Commodore Knock Sensors for 5.7 LS1

By: Jeff Rolfe on 30 April 2019

There are many "copy" knock sensors on the market for very cheap prices. They look like they do the job, but don't be fooled. I recently purchased some cheap knock sensors for my vehicle and after installing them and reinstalling everything else, they immediately threw fault codes which caused my fuel usage to increase to in excess of 30 litres per 100km. I had to pull everything down to remove the knock sensors which was very difficult. The centres of the knock sensors which have the 22mm 'bolt', spun in the lower casing. I virtually had to destroy them to remove them. The genuine knock sensors are made by AC Delco and are the only ones that you can be confidant with. I saved well over $100 for the Australian Online Car Parts item when compared to dealership prices.
