They do not fit. Different sizing of the orifice that goes into the fuel rail AND a larger O-ring, yeah it's obviously not going to fit.Super disappointed this was misleading as I write this review in a Lyft on my way to work. Ugh.

Bought as a quick replacement for my factory Toyota Denso injectors to be rebuilt and flow tested. After installation they immediately cleared up the idle on my car. I wish I had a flow tester to test these, but for now they work. I utilized the o-rings and seals that were provided with the injectors and no issues. Vehicle is a 2003 Toyota Matrix XR 1.8L VVT-i.

Worked great

2006 Toyota Matrix - Perfect fit, easy install, great performance, and significantly cheaper than other options. Highly recommend

The flowrate was tested compared to my stock injectors and they had 25% higher flow rate. the spray wasn’t atomizing as well as my old injectors.These gave my car the po172 code( rich condition) Im staying with my stock injectors!

Installed on an 2004 Toyota Matrix XR (1ZZ engine). Was pretty easy to do without leaks. You have to be careful about cleaning the area and applying a small amount of grease so they slide in without the o-ring coming out of place. That is why they leak for most people. I did have to remove the black bushing.

Amazing price good quality. Delivery time is was on time

So far, it's working as intended. I have tried other fuel injectors, but none lasted more than two months. We will see how long this one lasts. I am very happy. Toyota Corolla 2004.

These inexpensive 12-hole fuel injectors are working fine on my 2005 Toyota Matrix XR after a week of driving. No leaks. For the money, you can't go wrong. I called a local Toyota dealership to price new Toyota Denso injectors. I was quoted $293 EACH. Plus tax! So, about $300 per injector. $1,200 for all four. I thought I'd try these after that shocking price quote!Note: Use caution when removing your fuel rail. First, learn how to depressurize your fuel system and how to properly handle, contain, transport, and dispose of fuel, before attempting to replace your fuel injectors.You have to be careful inserting the injector into your fuel rail hole. This is likely the #1 reason they leak upon installation -- improper sealing of the O-ring at the fuel rail. But, if done properly, they shouldn't leak. I read a lot of reviews first and went to AutoZone and bought the $7 Fel-Pro O-Ring kit to replace the O-rings that came on the injectors, because reviews said the ones that came with these onexpensive injectors didn't fit well. After replacing the O-rings on these new injectors (the Fel-Pro ones seemed slightly smaller), I installed the injectors to the fuel rail, using a bit of spindle oil (mineral oil) on the O-rings, and then installed the fuel rail to the engine. Started up. Had leaks because the Fel-Pro O-rings didn't seal. Took it all apart again, and replaced the Fel-Pro O-rings with the O-rings that originally came on the new fuel injectors, and they work fine now with no leaks. So, you may, or may not, need the Fel-Pro O-rings. Might depend on your car. Whatever O-ring you use, you have to be very careful not to let it get twisted, or pulled off the recessed groove it sits in on the injector. That's why you must use spindle oil, or some other lubricant, when installing the injectors. You might get away with installing them dry, and they seal that way, but chances are, they won't seal correctly if installed dry, because they will twist and/or come out of the groove in the injector from friction when pushing them into the fuel rail. (In a pinch, gasoline can be used as the lubricant for these O-rings.) The purpose of the lubricant has little to do with any long-term sealing effect..., it's to help keep the O-ring in place in the groove on the injector, upon installation.Keep your original injectors. They are a direct fit for your vehicle and are likely well-made. Almost any injector can be rebuilt, or just cleaned, and perform well again. These inexpensive 12-hole injectors are working fine in my car after a week, but I don't expect them to last the 175K miles I got out of the original DENSO injectors -- which are still good, but need cleaned. I will keep the original Denso injectors, clean them, and get new rubber seals for them; then, put them back in the car when these inexpensive ones start to show signs of weakening. Since I don't know when that might be (Tomorrow? A year? More?) I will get the original Denso injectors ready now in preparation for that day. So, for me, these are "temporary" until they start to decline. I can also use them as my core injectors and keep my originals, should I need to ever get other injectors that require a core.

Didnt fit my 2000 corola
