    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.
