flint54 Posted October 21, 2011 Share Posted October 21, 2011 If you get in touch with these folks: http://www.precisionautoinjectors.com/ right here in Orlando, or better yet go visit them, they can probably tell you everything you ever wondered about injector interchange and application.

echdaviem Posted October 22, 2011 Author Share Posted October 22, 2011 awesome! thanks alot for the help. those ford injectors, will they affect my fuel mileage at all? if it gets better, great! I just don't want it to get worse. not that I'm replacing them hoping for better mileage. Link to comment Share on other sites More sharing options...
mnkyboy Posted October 22, 2011 Share Posted October 22, 2011 Unless something is wrong with your current injectors you most likely won't notice any difference in performance or fuel mileage Link to comment Share on other sites More sharing options...
