Port Injector cleaning results
 

Used this shop in PNW in snohomish WA that just does injector cleaning and thought I'd share the test results. Only did my port injectors. Very happy with the service.

This shop also offer LIFT TIME cleaning for the same price ~90$! as long as its the same injectors and you've owned them. This guy also replaced all the seal/orings/filter which saved me $80 from Subaru etc. Had to give them a shout out. Also super quick turnaround (half a day in my case)

My injectors have ~50K miles so they weren't that bad.

Is it necessary at 50k? Dont think i've ever had to get injectors cleaned. My old mercedes turbo diesel probably could have used it at 200k but it still started up every time with barely a crank.

It varies with use case, but on ethanol, you definitely want to get the injectors cleaned. Looks like OP's injector's were in pretty good shape.

DI injectors are more important to clean than PI, as the DI is what is used for fine fueling requirements.

Not all fuel injector cleaning services can do DI.
