Fuel injector cleaning serivice recommendations?
 

I recently picked up some used Mazda S5 non-turbo fuel injectors (N350-13-250) on Ebay. Looking for recommendations on a good cleaning & flow test servicing shop?

over the years, i've heard good things about the following:

https://www.injector.com/cart/pc/home.asp

https://www.rcfuelinjection.com/Stor...ector-cleaning

I used RC fuel injection to clean mine several years ago. IIRC everything went good. Injectors are still in the car and working fine.

Ok, thanks. I'll checkout their website. If I recall, Engine Labs, a email newsletter that I receive, recently had a article about RC and their injector services.

Ok, thanks for the recommendations. I'll checkout their websites. I used Marren Fuel Injection (injector.com) once before about 20 years ago. Had no issues with their services.
