AUS Injection MP-10851 Remanufactured Fuel Injector

I HAD 200000 miles on a 2000 Xterra originals.Easy install. Took 10 minutes. Fit like a glove and whent in smooth with very very light petroleum jelly on rubber o-rings. The petroleum jelly is a MUST!! Grabbed only one to replace a bad thumper but am coming back to grab 5 more this week. Working great. Perfect fit and work perfect. Listening to it through stethoscope sounds new and clean.200 miles and zero problems.2000 Xterra SE 3.3l 4x4.UPDATE:Bought 5 more and now all are replaced. What a difference! 400 total miles on them. Original engine with 200000 runs like brand new and very strong now. If you had leaky injectors for a time (like me) you will experience some burn off at first from random misses and carbon buildup. After putting them through the paces and doing a overhead spray clean smooth as butter.Fair price and solid product. Seller/manufacture was great. Would not hesitate ordering again.

Worked great, and about 1/3 of the price from any local auto-parts store.Have to drop one star due to it says "All injectors are lubricated prior to packaging ensuring a trouble free installation" I bought 6 and none were lubricated. I had some quick lube that works with this so not a major issue for me.

5/6 were defective out of the box. Lower seal isn’t the correct size, I heard before doing the job that you should only use hitachi and after spending several hours moving around injectors and rediagnosing the problem I wish I had of. Especially since the price of them here on amazon is only a couple bucks. Which I didn’t know at the time. I tried these due to good reviews, hopefully you’re experience will be different than mine. Even as a professional technician and shop foreman, removing these injector on an xterra isn’t a fun job. Especially the first time you do it. The fourth time isn’t fun either though.

Product functions very well. A little elaboration here may save you some grief - read on. Admittedly, I did not heed the rebuilders recommendation to replace all six injectors. They stated the short duration on times associated with idle and low RPM's would suffer because the old dirty injectors would not perform as well as the rebuilt injectors which I interpreted as just an attempt to sell more product. I originally had one known bad injector (cyl 4) and decided to replace only the three even numbered injectors due to their location beneath the upper intake (fair bit of work to get to...) and the attractive price-point of these particular injectors as compared to new replacements. I ended up with essentially the same symptom (misfire) only now it was random and not specific to cylinder 4 - just as the rebuilder had warned would happen!!! I subsequently purchased and replaced the other three for the odd cylinders and everything worked - smooth idle, no misfiring and no more DTC's or the associated trouble code(s).

2 out of six was in bad conditions and dirty. This may not happen to everyone but was very upset to see they was used and not cleaned!

Worked as advertised. A couple of the 6 I purchased were a little buggered up, clearly they were abused at some point prior to re-manufacturing, but all 6 functioned perfectly in my 2000 3.3L Pathfinder.

Works good.Perfect fit for my Pathfinder.

I stuck this in place of the injector from #4 cylinder on my 1996 Mercury Villager. It was packed plenty secure and had a warning I wish had come with another injector I purchased a couple years ago from another website. It's in #5 right now. The o-ring should be lubricated and the injector should go into the fuel rail with only a modest push and twist. The o-ring on a earlier purchase was the correct diameter but was too fat. I noticed the difference but tried to use it anyway since I figured the rebuilder must know what they're doing. If not for good plug wires I would have had an engine fire due to a fuel leak after a few hours of run time. If the injector don't go in nicely then something ain't right.If you are wondering if you have a bad injector then maybe you need a mechanic's stethoscope for around $12.00 it is a must have. With the engine running and probing against the retainer cap, a dead injector has a hun hun hun sound and one that's working goes thick thick thick.
