I was looking to get 24lbers and was wondering if anyone had experience with the 4 hole injectors I think they're also called design III. I wasn't sure what the difference was so should I look into these or just the standard ones.
i use a set of "three hole" injectors in my stroker. I don´t know if they are better than the stock ones but the spray pattern is possibly more effectively.
The left one on the picture is the new one (Accel) and the right one is the stock injector (Ford).
the 4-hole design atomizes better and I have seen flow tests that show they flow ~1 lb/hr more than a pintel design. I run the Explorer 4-hole 19# injectors in mine.
