XtremeAmazing 6pcs 4-Hole Upgrade Fuel Injectors For 99-04 4.0L Jeep Cherokee 0280155784

1st order of these injectors were horrible enough with code issues for shorted and open injector error codes. I was able to get them to sed replacements they were worse 2 of the second set were flooding the egine to the point were I got stuck on the test drive after istalling them. I almost had the car towed I limped home and removed and reinstalled the originals knowing at least the car would run until I figure out what to do next.

All 6 of these were bad. They dumped fuel into my engine when the ignition was on. I spent days troubleshooting before I figured out they were all bad. When asked to return, I was told that once they were put in the vehicle, they are mine.DON'T BUY!!!

Stock injectors were cracked and worked ok, but these made my 99 WJ run even worse. Just seem to be dumping fuel and making it run horrible. Guess it's what I get for cheating out. Ordered Bosh like I should have the first time.

When these arrived I installed them without any issues - The O-rings fit just fine with just a light layer of lubrication (I mean super light - grease or WD-40 worked perfect). Afterwards my 2001 Cherokee XJ was running SUPER rich and would not lighten up. Left them in for a few days just to see if the computer would re-calibrate the flow through the fuel rail or injectors... NOPE. Ended up taking them out and replacing them with new OEM injectors, which went in and immediately fixed the issue.Moral of the story: you cant upgrade to injectors that inject 4x the amount of fuel without also upgrading other components and expect your vehicle to run the same as before.

Don't buy this product !!!!!!!!!!! Ever since I put these fuel injectors in, I been having fuel dumping in my engine oil. stay away from these will cost you more money in the long run. Spend the extra cash and buy $70 or better such as bosh.

Received the Injectors quickly but was very displeased with the performance of them. One Injector was actually bad causing an engine light with an open circuit code for the injector. Emailed these guys and they said a new one would be shipped but would come from a foreign country and would take a couple weeks. Never received the new injector. Would never buy again.

Installed these about two weeks ago. Seem to be working well (although, honestly, anything was an improvement to the old ones). I had some difficulty inserting the injectors into the rail, but solved it by applying the tiniest amount of silicone lubricant to the O rings, that way they slipped in without tearing themselves apart. Otherwise, thus far a solid product.

Out of the six I have one that's leaking severely and causing misfire on cylinder five trying to get a hold of this company without having to go through Amazon because I can't take the injectors out and send them back then I have nothing. all I want is one replacement to make it right so please email me or contact me then I will correct my review to a good review.
