I have engines with 200,000+ miles on original injectors, I don't necessarily consider them to wear out at a given mileage. As long as the fuel filter does it's job to keep clean fuel flowing to them there really isn't much in them to wear out - newer, direct injection injectors are a different story. If I had a car sitting for awhile - I'd be more inclined to replace, as various environmental contaminants can clog them when sitting.

With that being said, I replaced them on a recent engine rebuild I did because they only cost a few hundred bucks and I was already in the engine rebuild for $2k+ at that point and didn't want to leave anything out.

FCP has M62 injectors for $264 for a full set. Send them straight to someone to flow test if you want, I probably wouldn't bother on new or rebuilt injectors though - the rebuilt ones (by GB anyways) are flow tested after being rebuilt and I assume the new ones are too. It's a little cheaper to get your current ones flow tested - but after flow testing, shipping (if required) and new o-rings I wonder how much you'd really save.


Not sure what ohming them out is going to tell you... the more common failure is insufficient flow or uneven flow between injectors.
