What is the stock size (i.e. lb injector) for a 1998 F150 with a 5.4L. I've heard different sizes so far, 19lb, 28lb and 32lb. Where can I find this information?

 

HI!... Your stock injectors are orange. They are 19lb'ers. The stock injectors can support up to 304H.P at the flywheel.

 

Ok Troyer ORIGINALLY sold me a set of SVO 19lb injectors. Said they would work. I called a dealership he said they were bigger. I call Troyer Perf back and she says they are too small and the injectors are a little bit bigger and would have to have a 24b injector. Damn this spark plug change has turned into a cluster F#@K.
