I was browsing on ebay and came across an auction for a set of stock Ford 19lb injectors. The seller noted that these were for speed-density and were slightly longer than mass-air type? I thought all 19lb (yellow top) injectors from ford were all the same lenth? Can someone confirm this? thanks

 

They should be the same length. Does it list a part number? I'm running injectors for a mustang (mass air) on my truck and they are just the same size as the ones that were on the truck originally. What's the auction number?

 

They should be the same length. They are the same injector for a MAF car and a Speed density car.

 

The auction has already ended but thanks for the input. I kind of had a feeling they are the same.
