Good afternoon,

I'm curious what everyone's injector service interval is? I am running ID 1050 primary and 1700 secondary on my FC 6 port turbo since 2021 running E85 primarily 80% of the time since. I use 93 octane only on long road trips out of state (which was twice)

I've replaced the 10 micron AEM microglass filter annually but i've never serviced the injectors. I've also replaced a weak Stealth 340 once since 2021. All fuel hoses are Gates Barracuda (bio fuel safe)

thoughts?

 

I don't know of any hard number for a preventive maintenance injector service interval - seems most folks just seem to service them when they are already experiencing problems or suspect a fuel injection issue. But with that said, I think you should change to a filter that can trap less than 10 microns. From what I read, both Injector Dynamics and Bosch both recommend filtration down to 4 microns IIRC; though the best filtration I could find on the market about 3 years ago is 6 microns. I went with a Fuelab # 81831-1 filter, which is spec'ed to filter down to 6 microns, and has more than enough (like double) the flow capacity of my Walbro 450 LPH fuel pump. Also, the 6 micron filter element within it is replaceable.

 

with the stainless internals of the IDs, good filter maintenance and running the car regularly, even running e85 i cant say that servicing the injectors would be required at all honestly. for your own sanity, you can service them now and see what the data comes back as and it will set the interval for you. i suspect if you did that, they would be functioning just as well as they were on day 1. being a good owner goes REALLY far with reliability as you are very much a representative of

 

^^^ This. ^^
"Bosch provides a specification for protection of electronic fuel injectors, which is a minimum capture efficiency of 87% at 5 microns, and 100% capture efficiency at 35 microns." Other than an Injector Dynamics F750, good luck finding that filtration performance. (Yaw fan boy disclaimer here).

 

The port injectors in OE applications are essentially immortal, the only failures you see anymore are failing windings in Chrysler 3.6s.

Cars do not have replaceable fuel filters anymore, it is part of the fuel module and is a life-of-vehicle thing. I cannot remember the last time I had to replace a fuel pump module for anything other than cracked plastic (Hyundais are bad for this)

I would assume that aftermarket injectors are based on OE level technology, given that they come from the same source.

 

Thanks all!!
