Description:

These are newer technology fuel injectors as they don't use a pintle cap with holes but instead a needle seat I belive they're called. It helps prevent clogging and for precise fuel control. They are knock offs of I belive they called Siemens deka brand so that's why there are no part #s. Just because they're knockoffs though doesn't mean they don't work 100% as they're supposed to. I've had 0 issues running these.
I replaced all the fuel stuff on my car like cleaned tank,  replaced fuel filter , fuel flush and ontop of it I ordered new bosche 550cc injectors because I put in a lowball bid and the seller accepted it. So why not ?
these 550cc injectors i removed had 0 issues what so ever and had no problem fueling my built engine ( head , cam , full Bolton  and sprintex at 21psi ).
the extra 4x Orings included I used are spacers in the fuelrail because these injectors were ever so slightly shorter than stock one. You can buy fuel injector hat/extensions but the Orings work just fine. 
I ran these for about 1yr and 10k miles only..
they did just recently have heavy duty fuel system cleaner ran through them and theandnother tank of regular 93oct so im sire theyre clean AF internally..
65$ shipped to lower 48$ , it will be 60$+ shipping then.
