they cost $125/$130 per injector plus u will need height adaptors $15 per injector, as the injector size is 3/4 and is a shorter injector, also u will need wire adaptor plug $20ea (per injector) to suit the injector factory wiring harness. as they are different size to standard. add all that up not so cheap mate. if u look in my classifieds section (car parts: top of page 2) I am selling the lot for only $650 just a reminder they are genuine id1000's (injector dynamics). not the style id 1000's that are selling on fleebay.
