So ive searched and searched about installing these ford or camero or whatever injectors into a 4.0... most things i found were for the non H.O. motors... ive got a 96 H.O. and cant find crap... ive found people talk about them but noody says... stick this injector in your H.O. motor for alittle added power and fuel economy... read that none H.O. motors have 19# injectors and HO's have 24# stock but then people are still saying to put the 24# out of a ford in a 4.0... what the crap... its the same injector? They say to only stick a 24# in a stroker... but what if its a HO? Then they just start talking about the numbers of the injector and dont say which color they were so i could go find them... Anybody actually done this and it work right? what did you use and from what... thanks again guys for clearing this up!

better spray, better fuel combustion, so on... im planning on doing it soon.
24# ford blue top is what ive been told, direct plug in... that is for the newer motors.... the renix only should use the 19#

19lb injectors shouldnt be used in a HO....The HO injectors ranged from 21-23lb So you can install the 24LB Ford Blue tops...They were installed in some Ford trucks and Lincoln mark's

you don't want to get cot up in lb ratings
look at flow rate at operating psi of the fuel system on the vehicle you are going to run them in
