New Style vs Old Style Injectors - Same Dimensions?

I am currently looking to purchase injectors for my Project, Ford 4.6 DOHC. Can anyone tell me if the new Pencil type injectors are the same overall size as the older type? Are the ends/o-rings the same size and distance apart as the older type. I realize that there are more than one type of electrical connector on them, but was wondering if the newer 05/06 Mustang injectors fit a 98 Engine? (fuel rail & intake)

Thanks, Paul

If your refering to the siemens (skinny body) injectors yes they should be the same length and the oring diameter should be the same. The older 4.6 had standard bosch injectors. Ive used the siemens injectors to replace the bosch ones in a vw droped right in.

Thanks for the info. Are the new pencil type injectors High or Low impedence? (or do they vary?)

No problem. They vary. The stock ford ones that ive got laying around from 4.6 sohc cam engines ive ohmed out and they were high impedance. Ive seen the higher flow rate ones for sale on the net available in high and low impedance so you never know. The ones that were installed in my buddys vw were 650cc high impedance.
