I have a set of 6 555cc yellow side-feed fuel injectors for sale. They are in great shape with ~10k miles on them. They come with the harness clips too if you are upgrading to the newer style. BTW, the newer style injectors are said to be more reliable and have a better fuel atomization than the older style.
$400 shipped (firm) with the clips. Email me for pics or for more info if needed. Thanks for looking.
