MOSTPLUS Flow Matched Fuel Injectors Compatible with Ford F150 F250 E-150 E-250 Lincoln Mercury 4.6L 5.0L 5.4L 5.8L 0280150943 0280150939 0280150909 (Set of 8)

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

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.

product came in and i checked the vlaves inside the injectors with a 9v batter and test leads and everyhting works as should

Ok

Warning the over rich factor will plug your cat. If you are not careful. I got these injectors while rebuilding the 5.8L in my 1993 f350. They work and fit great but my mileage dropped to 8.35 miles per gallon. I have seen several answers say these are 24lb/hr injectors but damm. I have good power but this is just a little over stock build. These injectors are way over kill for a daily driver. My mileage should be 15 mpg or so. For a performance build they should work. I’ll be pulling them out at the first opportunity and replacing them with some 19lb/hr injectors. I should have known not to get them the price was right but in the description it says crap flow rate of 220cc/min. I have tried to find a conversion factor to change to something recognizable and can’t find.

Work like OEM parts, excellent.

They have a steel casing and work perfectly

Overall, I am happy with the set of injectors. However, one of the injectors was faulty, and I recommend testing each one prior to install to save yourself some frustration. You can do this in short time by doing the following:1. Read ohms resistance on the coil.2. Use alligator clip leads to hook up coil to car battery and clamp leads to pins and listen for the “click” to know it’s working.3. Clamp leads to pins and blow through the injector. Air should not go through when de-energized but will flow when energized.Beyond the one failure, the injectors are performing well, so overall I would recommend these for the price. If they wear quickly, or more issues arise with use I will update.If the only service you are performing is an installation of injectors, this probably wouldn’t be too difficult to diagnose, but if you do a service replacing coil packs, spark plugs, and injectors at the same time, isolating the problem can waste a lot of time.
