    Got them installed by my local shop. So far so good. They come very well packaged and were shipped the same day I ordered them. Great people and great product.

    Fantastic shipping speed and customer service. The injectors themselves were individually packaged with great care and considered. After installing these injectors all of my intermittent misfires disappeared. Also picked up some performance and gained a noticable bump in fuel economy as well. Worth every penny!

    2004 Tacoma Dbl Cab 5vzfe Manual Trans, 265-65-R16 Cooper ST Maxx with 219,000 miles

    Absolutely NO COMPLAINTS HERE. Arrived super quick. Injectors, plenum and TB gaskets are high quality. The injectors come with seals installed and are sealed individually in plenty of bubble wrap. Before replacing the stock Toyota injectors, I was lucky to get 16 mpg. After replacing my fuel pump, fuel filter and all six injectors I managed 21 mpg highway on BP/Amoco 93 Octane (Best gas anywhere IMO) @ 65mph. I noticed that I regained some lost power in almost all regimes. I do not lug in 5th anymore and can actually climb hills and actually accelerate. It might just be me but my RPMs seem to settle in lower when cruising at 65 as well.
    Took me 4 hours to install. It looks intimidating but its actually very easy to do if you take your time.
    Word of caution: DO NOT USE BRAKE CLEANER in lieu of throttle body cleaner anywhere in the intake as it will foul your #1 AFR sensor ($160) and you will suffer a P0031 code which kills your air/fuel metering efficiency. I didnt know that…I know now.

    Super pleased with my purchase from MWP. Got these injectors along with the 6x Banjo washers for my 98 4runner that has been experiencing a slight miss at idle and occasional hot start issues. No Cel…
    Changed everything prior to these including all new plugs, wires, coil packs, maf, iac, tps and these finally fixed the issue.
    Install was nice and straight forward following along with Timmy toolmans YouTube video on these. Only complaint was that one of the copper crush washers came a little bent out of shape but I opted to use it anyway and see what happens. No issues and everything sealed up as it should. Idle miss is now gone and accelerates much stronger than before. Great product and super fast shipping. Just picked up another set for another 4runner we’re working on!

    High quality fuel injectors! Put them in my 1999 toyota tacoma 3.4L 6V. Fit like a glove and runs very smoothly. Glad I got them,highly recommended!!

    Purchased these recently because I had a pesky misfire in my 3rd gen 4runner. They arrived to Michigan in 3 days. Installed them while doing my valve cover seals since I the disassembly procedure is the same and WOW.

    These things breathed new life into my 315k mile 5VZ-FE engine, which was putting a long with the original Aisen injectors. Feels like my engine is producing 30% more power, and the idle is ridiculously smooth. These Densos from MotorWest might be the best replacement option for the oem Aisen’s, in the world.

    As it turns out, my original fuel injectors were not causing the misfire; it was a worn out sparkplug boot arcing to the plug tube. However, I don’t regret purchasing these injectors one bit. They were a great purchase!

    Replaced the injectors I had bought from GB remanufacturing with the Denso injectors you sell. Within 6 months those GB injectors were already failing. Now that I have quality Denso injectors, my fuel trims went back to normal and the P0172 code went away. My 1999 4Runner runs great now. Wish I went with the Denso you offer first, I just didn’t know. I should have trusted Timmy. Thanks for selling a quality product!
