Fs: Rc 550cc Injectors With Fuel Rail
These are brand new. They use the same plug as stock and fit perfectly. The only thing you will have to do is buy a resistor box or wire in 4 resistors. I have it done on my car and it is extremely easy to do. Looking for 350 shipped OBO. The injectors cost more alone. Paypal is best, looking to move these quickly if possible.


I had some RC 450s for a short time that worked perfect. With the 12mm (i think) orings its a real tight fit in the rail and manifold and I never had any issues. Also ran some DSM injectors that are the same style with no problem.
I think MJ uses this style to but I may be wrong.

sorry to bring this a little OT, but my box came with that style.

and there some big washer/o-rings for the bottom.. but since the top doesn't go up into the rail all the way is it supposed to seal on that other rubber seal thing?

How mine sit in the rail the lower rubber piece is right against the rail but the Oring fits super tight in there. To get it in I really had to work on it with some lube. And then when it goes into the IM its all sealed and its tight in there where you dont need to use the stock clips even.

Need them gone. 200 shipped with rail. They will work I didnt even change anything mounting wise and the old ones I had worked just fine. Just add the resistors and you should be good. Otherwise maybe someone knows someone with a DSM that needs some. They are complete plug and play for them.
