As title says, what is the best cleaner for JUST THE FUEL INJECTORS. I have them removed so I can use a carb cleaner or something slightly more aggressive. I don't want to use a fuel system cleaner unless those are the best for just the injectors. Any recommendations?

Take it to someone who cleans fuel injectors and test them.

An injector shop. Have them flowed/balanced/professionally cleaned.

I was going to send them in but just found out that the shop I had install them installed different injectors than I purchased and specified(which is a whole other issue). I'm aware that the right answer is to send them in to get professionally cleaned and checked for flow and variance. However, I'm not going to do that. I simply want to attempt to clean them myself so that I can make the drive to a new shop where I will have IDs installed.

With all that being said, do you guys have any other suggested products for cleaning out injectors? Thanks.

I also forgot to add that these injectors are brand new so I don't want to pay to have them tested if I don't have too considering they are new and I'm about to swap them out. Have only been used for a few thousand miles. I think my fore fuel filter isn't doing it's job correctly and I will be switching that out with a better filter.

I use either the GM Fuel injector cleaner or the Motorvac MV3 cleaner. These are designed to be used at the fuel rail with a pressurized canister of the detergent & fuel, NOT dumped in the fuel tank (return line to tank is also plugged so it can't be sent there). Not exactly sure how you're planning to do the job, but this stuff works.

I always use the royal purple stuff, and a bottle of techron once a year

Why do they need to be cleaned if they're new? If the car is running bad they may not be tuned correctly in which case I wouldn't drive the car

Ya, that's pretty much what i did. I will also run some fuel system cleaner through it too.

I just found out that the Fore Filter that came with my fuel system doesn't do a good enough job of filtering the fuel. It doesn't filter anything out below 25 microns and it's only 14% effective at 25 Microns and then above that, the filter finally begins to do its job. I believe this is what slightly clogged my injectors. I just replaced it with a Fuel Labs 6 micron microfiberglass filter. Next step to is to get these shitty Bosch/FIC modified injectors out that my shop put in there (despite buying ID2000s from them and paying to have them installed, issue I'm working out with them) and get some IDs in.

KM177122

Probably. Once I get IDs put in the car then I will obviously be sending them out to a professional if they ever need cleaning/flow testing.

I use Techron, it works.

I pour a can of Sea Foam in my gas, once a year before a long trip. Do not know if it needs it, or if it does any good, but it gives me a warm fuzzy feeling, so I do it.

As an additive I've always liked Berryman's.
