Sometimes having the right tool is key
When it comes time to remove an aged 02 sensor here is a must have tool! Trying to remove a frozen sensor can be hazardous to your knuckles and your sanity. If you have not removed your 02 sensor in a long time I highly recommend you have this special wrench on hand. It can be purchased at many auto parts stores.
