changing injectors

[HEAVYHITR]

how long does it usually take to change a set ?

and should i change them to be safe? they have 143,000 miles on them ?

or is there any way to tell without removing them ?

and whats a new set usually cost ? should i put bigger in ? or is it a stock injector with diferant tip ?

thanks

Not hard. Common hand tools. I replace them all the time. Usually 2hours start to finish if I don't screw around. Injector bodies are all the same. The higher HP injectors only have large orifaces in the nozzle that can be removed and installed to any corresponding years of injectors (03-04.5,04.5-07,08+). Shouldn't need to change injectors at all with only 150k if taken care of properly. You can get them tested tho for $25 or so each if you desire to determine return rate, flow rate and balance.

Do not have to remove rail... Don't know why that's in there.

^^X2 on cleanliness! Might want to grab a bottle of brake parts cleaner. Also check this tool out, makes removing the crossover tubes a whole lot easier.
