Is there a quality different between the two? how are they going to differ from eachother? Im sorry i have a little bit of a hangover if i'm not making sense.

 

well i'd say the main difference is in what you pay for as in what you get. i just bought some dsm's the other week, yet to install them but its like anytime you buy something used, you are taking a risk. but then again sometimes even with new parts in the aftermarket world its the same deal. i think i feel ok about buying the DSM's because they were made by a respected company that was sure to have put some R&D into the product. as for RC i have yet to really hear anything bad about them, and **** i am replacing my RC's with DSM's. hope that helps on some insight

 

i would go with the RC's...their new with a warrenty...u really never know how many miles are on a used injector....the RC's come tested with paperwork and the proper seals that you will need...if your tryin to pinch pennys get the dsm's

 

I wouldn't think there would be a noticable difference except one set would more than likely be new, and one would be ?? years old.

 

thanks guys, and with something as important as injectors i think ill go with new ones.
