Found them on e-bay, there was a few sets on there earlier this week, all went from 50-85 bucks. The set my buddy had he thought were 28.8's ended up being the 26.2's, good thing I double checked first, I found a real good site for injector flow rates and it seems to be one of the only ones that is right about the flow rate on these injectors rated at 4 bar,
www.witchhunter.com lots of other good info too.
