Fuel injectors
They were very good product worked excellent I was intending to upgrade to a bigger fuel injector ticket I get some more power which I did but they're not to make the check engine light go on and I did not like that I would have had to upgrade my map sensor to a 90 mm I decided not to spend the money on that so I returned these injectors

Running Lean
These were installed a few months ago on my '92 F150 and lean codes started coming on. I chased everything around the motor, transmission, and exhaust because of the jerking/hesitation I was experiencing and it turns out that the injectors just aren't good.

Didn't work for me.
Had a crack in the intake manifold on my 2002 F150 so when changing that decided to replace coils, injectors, plugs, etc while I was in there. Finished the job and the truck runs great! No misfires, no stumbles, just runs great. But is running too rich for the computer to compensate. Check engine light with P0172 and P0175 codes, and Long term fuel trim of -29 on both banks. Had to take them out a reuse the original injectors. Sad because the injectors worked fine, looked well made, just ran too rich for my truck. Maybe needed a bigger throttle body.

They look like injectors, they don't function as them
My 97 expedition with a 5.4 triton developed and intermittent misfire in cylinders 3 and 6. P0303, P0306. New spark plugs and coil packs installed. Issue remained so injectors thought to be culprit. Punched these as the price was very reasonable and decent reviews. They must be paid reviews because my truck went from having an intermittent misfire to running so rich the thing barley runs. Test drive resulted in blinding the driver behind me with white smoke and likely killing my catalytic converter. Vehicle has no power after installation. STAY AWAY FROM THIS SCAM. Total waste of money.

works better than expected, great price
I was nervous dropping this order reading some of the other reviews and the price which was far cheaper than the store. My 2000 Mustang GT fired right up and ran great . Also did plugs and new coils .

They work
Worked for my brothers 98 f150 with the 4.6 v8. Did run a bit rich the forst few startups but the computer seemed to adjust shortly after that. Good value for the money.

Came with two different injectors out of the eight… all injectors have different spray nozzles from the originals
