I am working on restoring a Jeep when I discovered the injectors were all gummed up and not working at all. Ordered the economical ejectors for a quick delivery. They arrived as scheduled but were missing parts and looked as though they were recently removed from a vehicle. The were loose in a box inside a sealed plastic bag. The seller quickly responded to return request and had the new parts in 2 days. They looked great, were in individual bags, and appeared as described in the add. I quickly installed them and the jeep fired right up and ran smoothly. The seller did a great job responding to what appeared to be an error in packaging or somebody returned the used items to the seller for a refund and it slipped through a quality control check. The injectors are starting great and the customer service was spot on.

This made a huge difference in the performance of my 98 Jeep Wrangler. Easy to install and well worth the money. I would buy them again but hopefully I won't need to. I recommend this to anyone including family and friends. I read a lot of negative reviews and was apprehensive but decided to purchase these 4 hole injectors despite these negativities. I am glad I did.

1998 jeep wrangler was throwing p301 code. Started with electrical (cap, wires, plugs, coil pack before doing injectors. Unlike a couple of reviews and or YouTube reviews, the stock retaining clips on original injectors snapped back on and worked fine! I can only guess that.someone did not seat them all the way. Ran it 20+ miles on a test, no leaking and seems to run smoother for sure and so far no check engine light anymore.. hopefully this was it! 4 out of 5 only because I haven't had a chance to run it more...hope the review helps someone else..

No way to sugar coat it, these injectors are trash. Needed some in a hurry and these are what I found. Made my truck run like garbage and I lost 5-8 mpgs. What's worse is that I have been trying to figure out why my truck was running so bad and have probably put about $300-400 in new sensors and parts trying to make it run right. After about 6 months, I began to wonder if my cheapo injectors were causing the problem. Replaced them with some of Trevor @ skankfoot racing's injectors (refurb Bosch 823). These came with a testing sheet that show that all injectors were working as they should. These cheap injectors are an expensive mistake. Symptoms of these injectors: running rich. Like really rich (gas coming out of the tailpipe, smoking badly). Would idle at 750 for a few seconds and then almost die, recover itself, and repeat the process. If you are having these symptoms i would replace the injectors with the ones I mentioned above.

Fit is tight but some jelly or grease definitely helps. Definite increase in speed, hp, torque and gas milage. Electric connection could be better but works exceptionally. I have a high milage 97 grand cherokee and I'm very impressed. Excellent, coast effective, OEM replacement that works better than OEM.

Installed these on my XJ in about 45 mins to include painting the fuel rail. I was skeptical, but they fit great & no problems to speak of. Idle is much better. Slightly better throttle response on the bottom end. If you're looking to upgrade, purchase these.

Didn't work for me

They are slimmer than stock injectors but seem to work fine without leaks. Just make sure to order the correct electric connector and after install pull them back out enough for their injector sides to fit into stock locking clip slots. I can not compare milage because I made several changes at the same time. 1998 Stock fuel injector bar, stock electric clips, and stock locking clips used. Jeep motor is not missing and runs better.

I’ve had these two weeks in a brand new crate motor 4.0 the one is stuck open and bleeds the fuel into the cylinder and when I started it up might have done damage to it. Do not absolutely do not take a chance with these
