Whats the difference between injectors

markus2 · 08-26-2009, 10:31 PM

I have a mk7 with 24 lb injectors. Gonna swap back to 19's cuz the bottom line is thats what the computer is programmed for and Im sick of idle and flat spot issues.
So question.
Motorcraft injectors are way to expensive for a set of 8. (and yes i want new ones)
But i see ford racing makes a set of 19 lb injectors for a price of 230 for the set. But there is warning of not installing on stock cars on most of the sights selling these.
My mk7 is programmed for 19's-so will i have ANY-ANYYYYY drivability issues if I go the more affordable route and install the ford racing set as opposed to a motorcraft oem set (motorcraft runs 80-110 range dollar wise-tooo much for me)

Any help guys would be really great-I just want my car running smooth again.

Thats a completely different set up from what I am running.
I just want to know the difference between the injectors from motorcraft and the injectors from ford racing-both being 19 lbs.

The link you posted is for coil packs-my system has no coil packs.
my 01 lightning did-BUT NOT BY 91 lincoln mark vii.

So I contacted ford racing directly.
The ford racing 19lb injectors are identical to the "motorcraft" oem injectors.

I swapped in the set of 8-and have not looked back since.
Still working on the drivability issues-it can never be easy

The difference in case you're still wondering, is the Motorcraft "OEM" injectors are what they charge your balls off for at the stealership when you come in to have them replaced. The Ford Racing ones are what they sell to guys like us, because they know we'd never pay them that much for their parts.

roger than man.
im learning... slowly, but im learning.

Similar to my experience with buying the Motorcraft o2 sensors that are made by bosch. in fact next to ford logo is the bosch logo.

Motorcraft... phseeshhhh
