    Hello all the experts and experienced priusers out there, I need your opinion regarding the subject. A set of oem remanufactured or a set of descent new after market injectors both costs approx $150, which one in your opinion would be a better option?

    Do you actually need new injectors or would cleaning them be enough? If cleaners you put in the tank aren’t strong enough there are systems that connect the cleaner directly to a fuel rail.

    Sorry no info on rebuild oem vs. new aftermarket injectors.

    Used many fuel additives, runs ok (yet not normal), while the cleaner is in the tank then goes back to same, figured rather spending more money on cleaning by fuel rail, might as well get new injectors, atleast those will be new.

    OEM remanufactured is a marketing term by the company that is selling the remanufactured injector, that obviously came off a Prius. I don't see dealers offering a remanufactured injector. Remanufactured/rebuilt axels, alternators, power steering pumps, etc; some of these parts are not applicable to a Prius.

    Internet search "Toyota OEM parts." Most of the results will be dealers who have an online site, w/ prices less than their retail in-store prices. You will have to search and figure out which dealer is best for you based on shipping and tax. If you are still in the LA area, I like Camelback b/c they are close (Phoenix), no sales tax, free ground for most items (purchase minimum required, parts size, and weight restrictions).

    New OEM Toyota injector is $115.52. Don't know if the insulator ($3.56) and o-ring ($2.28) are included w/ the new injector. Perhaps these pieces are required if replacing or doing work on an injector? You should call Camelback or a local dealer to find out. Obviously NEW is a no brainer now.

    Is there a way to test if an injector is clogged? Test by techstream or some other computer diagnostic equipment? Maybe just bite the bullet and pay a local dealership for a diagnosis fee? Maybe it's something thats fuel related, but not the injector. Maybe a weak fuel pump?

    The only thing I know is the car runs a little better with fuel injector cleaner, without it, it hesitates and runs rough. I unplugged the injectors and checked the resistance as per the factory service manual, which says the resistance should be between 13.45 and 14.15 ohms, my readings were 14.6 on two and 14.5 on another 2. One of the sellers on e-bay is offering 5 year warranty on remanufactured injectors, they are selling a set of 4 for $ 90.

    I wouldn't put much faith in Auto Dismantler selling 4 injectors for $90 w/ 5 year warranty. I just can't see any auto dismantler spending the time to do the "rebuilding," and "testing," that they claim to do. Dismantlers, take cars apart and sell the parts. I would really want to see what equipment they have and how they do their tests:
    Re-assembled with new OEM high quality components (seals, filters etc..)
    Pressure/Leak tested,
    Spray/Flow Tested,
    OHM Tested for electrical shorts,
    Disassembled and externally cleaned​

    I would have more faith in this company (Florida): Fuel Injector Flow Testing
    If you have a spare car to drive around in while they do the testing, and seal replacement, for $12.50/injector.
    Probably best to do their ultrasonic cleaning that includes, testing, cleaning, seal replacement, and filter replacement, for $20/injector.
    Fuel Injector Cleaning
    I just can't see the auto dismantler doing as good of a job, or better, for $22.50/injector ($90/4injector).

    I like this company's explanation of things.
    Why Refurbished, Remanufactured, OEM and New should matter to you | InjectorsDirect.com

    How good is your DMM you used to measure resistance across the injector coil?

    If original owner (first owner), have you been using quality gas (Chevron, Texaco, Shell, Exxon/Mobil, etc)?

    How many miles?

    Thanks for valuable information and tips about auto dismantler, I will perform more research on the links that you provided. The multimeter I have is a cheap one but I compared the results with a good /expensive from our companies maintenance department and the results were exact. I have always used Arco which is also a top tier (although cheaper then all other). 92K miles and yes first owner. I had never used a fuel injector cleaner up until 85K miles as I felt the car was loosing power.

    I'd stay away from Arco. In my opinion, they're not top tier. I've ever only had a once incident of bad gas; yep, Arco gas. Every since then, I avoid them.

    Almost forgot, what type of FI cleaner did you use? Most people here seem to like Techron FI cleaner. If you didn't use this, maybe one last try? Get the Concentrate Plus cleaner, maybe the 20gallon treatment bottle vs the 12 gallon bottle? $12 vs $6, at PepBoys. Just an FYI, you don't want to use a FI cleaner, like this too often. But since you are resigned to replacing the FI, I guess a $12 attempt couldn't hurt?

    I remember a long long long time ago, I read in a Consumer Reports review of gas using the BMW 100,000 mile test. This test involves weighing the intake valves on a new engine. Putting a 100,000miles on the engine using gas from one brand only. Removing the intake valves and weighing them again. Passing is zero valve deposits. Essentially the test is looking for valve deposits, which will reduce gas flow and power. Arco, along w/ the big names all passed then. Maybe CR ran the test again more recently?

    Yup I have used techron as well. I began with STP (couple tanks), then Chemtool (one tank until someone said that since it has acetone not recommended for prius's bladder tank), then Techron conc +, then Techron Progard 20 oz bottle (3 or 4 tanks), I have come to a point that when I feel like driving smooth and better I pour in a bottle of techron, I know it is not good to do this but somehow the problem just does not get fixed, all this time I have been trying learn and diagnose the problem myself and replace parts here and there (like TB, PCV valve etc), before changing these I had gotten the spark plugs replaced by the dealer per their recommendation.

    Here is another situation I am coming across, camelback Toyota pulls up part number 23209-21020 for my 2008 base as fuel injectors. However there are many sellers on ebay that sells a part number 23250-21020 but mentions that it also goes by p/n 23209-21020, the picture of the part has 23250-21020 embossed on it, not sure is this p/n 23250-21020 was an obsolete one and replaced by 23209-21020 by Toyota later.

    You could plug 23209-21020 into Camelback to see what it is. This part # might be the one might that got replaced.

    I'd be skeptical of eBay parts unless it's comming from a dealer who is also selling on eBay. Some parts might be genuine, others could be counterfit.

    That's a lot of FI cleaner you've used. I've only done a Techron FI cleaner once. But I've also only used Chevron gas as well.
