Well, it was about time this maintenance got completed!

I replaced the injectors on my Toyota Prius and wish I replaced EGR Pipe and EGR Valve and spark plugs at the same time. This work was completed in June of 2021, now today April of 2022 I swapped out the EGR I installed last year with the OEM EGR that I clean personally. Look at the difference less than a year my EGR was practically clogged!
