158-0561 New Fuel Injector

Fixed intermittent engine misfire problem, unless you like doing this job twice buy the seals for the two other injectors when you replace one.. I tried to cheap out and the other two leaked and lucky me got to do the job again. If you want to test for leaks before you put it all back together climb underneath the truck and pull the small wire from the starter, turn the key to the start position and the fuel pump will run. Beck/Arnley 158-0893 Fuel Injection O-Ring Kit

When received, it had the factory markings and looked like an OEM part. Ran well for about 1k miles, with obvious better gas mileage and gained loss horsepower. It is currently late April 2025 and in mid March, it started to misfire, worse than before. Looks OEM and worked well for a little bit, but I now need to buy another one. I will probably just fork the money for OEM injectors, even though these are about the price of quality reman OEM injectors.

I was worried about these not being sufficient for my 3rd gen 4runner, but they were. They're essentially OEM level injectors made in Japan. Good stuff. Pricey, but cheaper than new ones at local auto parts stores. As these cars get older it's harder to find these. For the price point you aren't gonna find anything better. I'm slowly rebuilding my 4runner, and these helped my fuel economy A TON. And acceleration is a tad better too.

Same exact part as OEM. Half the price. Comes with O-ring set. It has the OEM manufacturer stamped on it. You can not miss with this purchase.

After lots of research, and a month to reverse a failed eBay purchase which turned out to be counterfeit injectors which looked almost exactly like these, I found that Beck Arnley sells the exact same fuel injector that Toyota does (for the 3.4L engine) for almost $145.00 at the stealership, for much less. I purchased 6 of these and was so glad to find that they are genuine Toyota OEM parts that are just put into a Beck Arnley box and sold for half the price. A tip for anyone buying new injectors for their 3.4L. OEM injectors should all weigh close to 42.5 grams, give or take a few tenths to account for varying amounts of protective oil they coat the internals with. Most counterfeit injectors will weight less due to cheep and fast wearing light weight metals for the internals, and often weigh about 36.8 grams. I even found the counterfeits I had received even leaked on other purchasers, flooding one 4Runner owners engine with fuel, which hydro locked when he attempted to start it. Do yourself a favor, buy this product, save some cash, and stay away from eBay for any new fuel injectors, its really a gamble that could take away your cars reliability, or worse.

Ordered 2 of these Beck/Arnley injectors to replace a pair from my 2000 4Runner that were failing. Took them to a fuel injection specialist prior to install to confirm they were good (I've been reading about lots of bad injectors being delivered any more...crap Chinese products). Specialist put them on their equipment and at first they delivered no fuel at all (first photo attached here, new injectors are in positions 2 and 4). He cleaned them and re-ran the test and they delivered a terrible spray pattern—worse than the failing injectors they were supposed to replace. Second photo, you can see that the spray pattern is imprecise and has a splatter of droplets rather than a precise pattern like the stock injectors around them. Returning these and having to make the round trip hour drive to the injection shop again.

Saludos. Hace dos semanas adquirí estos inyectores, los mismos dan el rendimiento que mi vehículo necesitaba es una 4 Runner 2000. Lamentablemente compré unos de menos de $80 dólares sin marca y esto fue un total fracaso. Tuve que pagar al mecánico nuevamente para desinstalarlo quizás venían en mal estado o la calidad es bajísima. Estos segundos inyectores le devolvieron la potencia al vehículo. Recomiendo estos inyectores muy buenos para mi concepto. Llegaron a mi país sin problema.

had a bad injector on my 2001 4 runner. ordered this one since it looks identical to the factory one. Replaced the injector and still have a flooding issue on that cylinder. I have gone through all the diagnostic steps; fuel pressure check, compression, swapped coils, new plug, inspected wiring. spend the extra money and only do the injector once. Chasing your tail because of bad parts gets old quickly.

Purchased as a replacement to a suspected leaky fuel injector on a 2000 4runner (V6) - installed with no issues and has been problem free ever since.

OEM, made in Japan. Easy install, comes with all 3 o rings. Identical if not the true OEM manufacturer for toyota fuel injectors. Took approx 4 hrs start to finish as 1st time changing an injector and I'm not a mechanic!

So far so good! Fit great for my 1999 Toyota 4Runner SR5 3.4l 6 cyl.

Good fit for a 2000 tacoma 4x4 V6
