When they get old, they get hard, and if they don't crack or break off when you try to remove them, then they will break off the little plastic lip of the injector you broke off in those pictures. I try to avoid this when I switch them out for people, so thats why I cut them off every time. Its a much better method.

WOW, Thanks so much. I can sleep now over the lost piece. I have been thinking of a whole new route. What about upgrading to say 42.5lb injectors? ZZP offers a set flowmatched. Is this over kill for my current setup? My PCM was purchased from PFYC and was programmed by digital horsepower. Will I need my PCM programmed /tune again with new injectors?
Maybe I am answering my own questions here LOL, guess with all I am doing maybe a tune would be good anyway. I never did do a case learn. Guess I am on the fence if upgraded injectors are a good idea. I was gonna go with OEM but NAPA was about 114 a piece!! Since mine have 110K wasnt sure my best route here.

Your PCM will defintely need to be reprogrammed for new/different injectors.

Will I gain anything by doing it. Are they just for high horsepower mods? Wasnt sure if it was worth the investment.
I have a local memebr who can program PCMs. As long as the car is driveable until I meet up with him LOL

Unless your injectors are clogged or bad, I doubt new ones will be a big benefit..I'm trying to remember your mod list though.

With as many miles your has perhaps just getting cleaned and flow tested by a reputable place may be a cheaper better alternative.

Check out Deatschwerks they sell and clean injectors.
There is a place called witchhunter that does them as well.

I'll look into cleaned and flow tested. No sense in getting high perf if gains arent noticeable. My Mod list for performance is small, Wizaird CAI, MSD coil packs,
PRJ 10.4mm wires, NGK plugs, PRJ gen 3 fuel rails, Digital Horsepower programmed PCM, & U-Bend delete.

You definitely don't need aftermarket injectors then. I've recently seen a before and after cleaning video...It has me thinking about pulling mine and sending them in for cleaning and flow testing. I have 7 Ford Lightning injectors so I could use the 6 best.
