Hey Everyone.

I'm looking to purchase new injectors for my 2001 5.2L. I've seen that the Bosch #0280155917 (Ford #XL2E-C5A) is a possibility. It's a four hole design, 19#/hr. and an EV6 configuration.

Any thoughts on this?

 

Don't get it. 19L/hr won't work on your truck, no matter what anyone else. I have tried them, and asked many others who have, the only exception being if you put a lower regulator on your fuel line.

 

Not trying to get into a pi$$ing contest but I guess I'm the 'no matter what anyone else says' because I've been running the 4 hole 19# Ford injectors in my '01 RT for over 5 years now and have never had any problems whatsoever. Burn a perfect plug color, a lot smoother running engine and a little increase in power and mpg to boot. The choice is yours.

 

me too avoiding a pissing contest, but I ran FSM 24#'rs with a SCT -7% delivery and RETARDING the fuel sync 4* to floggin' outstanding results.. clean as a whistle a/f, purty plugs, and more throttle response...

injectors can be a tricky subject.. I studied it extensively before and after experimenting with many..

you can get by with 19#r's for either the 5.2 or 5.9, but you're reaching north of 80% duty cycle at WTO.. the perfect handshake is 22# in my humble opinion (which actually deliver around 24#/254cc per minute @ 49psi)... only because the OE cam in the 5.2 is more aggressive than the one in the 5.9'r do they drink roughly the same..

you can tune down or up for delivery, but in order to do so you'll need a wide band a/f gauge.. because most don't have that, most just guess.. guessing is bad..

you can program for a window between 19# and 24#- but you'll be pig rich w/24#r's @ WOT, and lean w/ 19#r's at the same.. the 22#r's can be trimmed by the PCM out of the box w/o issues, but you better make certain they are actually 22#r's.. a matter of fact, ignore the weight and look for flow in cc's per minute.. if they aren't listed select another that is.. that is treachery in marketing in an already treacherous situation.. that being buying/upgrading injectors.. folks pray on ignorance of consumers moreso there than most parts/pieces..

 

Are the 19#/hr injectors OE?

 

Not on the 42.5-45PSI pumps, on the older 35PSI pumps some had 19#

 

I'll get into a pissing match here for sure, 19lbs 4 holes on a stock motor runs pig rich!!! No were does the op say he has a tuner to adjust things, no were does he say he has mods to support the BIGGER Flowing injectors. Folks here have spouted that stock injectors are good for 400+ hp........ So why **** with them.

Op replace what you have with stock injectors.

 

Agreed. Who dares to challenge us?

 

I'll play your little game with you! I've been running the same set of EV6 19# Ford injectors for well over 5 years and have NEVER had a problem with running 'pig rich'! On the contrary, my '01 5.9 burns an absolutely PERFECT plug pattern, runs a lot smoother and even has a small improvement in performance AND mpg. You don't get even a small increase in mpg if you're running 'pig rich'!

Don't know what type of injectors you guys purchased but it damn sure don't sound like they were 19# Ford!

 

I just wiggle my original injectors around a bit and i still get 11.5 mpg! HaHa
