i have a set of four of these. however, ONE OF THEM LEAKS LIKE A ----------ER, so this set is probably only good if you need to replace bad injectors, or if you know how to fix injectors. basically, you are going to recieve three good injectors, and one bad one (leaks gas from the middle all over your intake manifold=bad ). make me some offers guys... or if nobody wants these, how much do you think i can ebay them for? i will try to post some pics of these later.
