By far exceeded my expectations!
September 5, 2017
1A aftermarket injectors.... $700 cheaper than OEM and the quality is more than what I expected. No problems with installation. After almost 3 weeks of hard driving I've had no issues at all. I just had to remove them again to install new knock sensors. Definitely exceeded my expectations! Write your review here. It must be at least 50 characters long. Consider whether you would recommend this product and what you like or dislike about it.
Not compatible with gmc 2005 sierra 5.3L V8
September 6, 2017
Not an OEM replacement. Form and Fit, but not FUNCTION. These injectors have 4 ports at the bottom, not 2 as seen on the 2 website pics. So the sysytem runs extremely rich to the point you get check engine codes for system too rich. I tried resetting the computer, it didnt help. 1AAuto was very good about the return, but fact is i cannot recommend these as a true OEM replacement.
Great Price, Delivered FAST!!

Everything about the order was great. They come without the clip that holds them to the Fuel Rail though. It didn't say they were sending them in the order... but wouidn't you know it, I lost several and cannot seem to find them anywhere online. They fit pretty tightly so their purpose may be unnecessary since they can't come out of where they're put into the fuel rail and the intake manifold. Maybe they're irrelevant... Not sure where to get them or what they're called other than maybe Injector metal clips. Aside from that, everything was great.

Easy instalation video was a great help A1 auto videos are the best auto repair step by step videos have used them for more than just replacing my fuel injectors
Fuel injectors bad
November 12, 2017
When i received the fuel injectors, I installed them and my motor got even worse. My original fuel injectors have 2 escape holes and the one i bought from you has 4 and I think it was giving to much gas.
8 pkg fuel injector kit 1AEEK00745
November 27, 2017
they look brand new, made in china. they are of the new 4 pin hole design. I think my 2004 avalanche is of the 2 pin hole design. I have not put them in yet. Keeping them handy for the day. My truck has 215,000 miles on it.
Very good product!
January 12, 2018
Installed on my 2005 Chevrolet 2500 HD 6.0. Very easy and Truck runs great.
March 26, 2018
The injectors showed up within a couple of days as expected. They fit without a problem however they don't come with new clips . The fact that they don't come with new clips is my only complaint and it's because I was delayed a day from fixing my truck because I can only get the clips from the dealer . However I would still recommend to a friend.
Very Disappointed
March 26, 2018
I bought my first item from 1A auto because of the great videos you guys do online. It was a replacement mirror and it it looked just like the OEM mirror and it was cheaper than the OEM price. I appreciate that because my car is at 200k, so any cost savings is great. These injectors were disappointing though and it kind of bummed me out because I thought I had found a great source for online parts. I decided to replace my injectors as part of a 200K service since a bad injector can ruin the 6.0L Yukon motor. They made my truck run rich and start throwing misfire codes. I replaced the ones that were throwing misfire codes with AC Delco injectors. Once I replaced the 4th injector, I just pulled them all. $1200 later plus the cost of the 1A injectors and a ton of my time, no more problem. You cannot sell these if they do not adequately replace the OEM injectors.
Fast arrival

The injectors look great! Gave them four stars because I havent had a chance to install them yet. Great company! Dont be afraid to use them for your products.
Bank 1 and bank 2 rich
June 17, 2018
After installing injectors vehicle trim values were -19 to -30 both banks. Replaced with oem injectectors and values were correct after reset. Contacted customer service and was refunded, less the shipping cost. Happy with service disappointed with product.

Best experience online order!
November 8, 2018
Add problems finding parts locally, looked on 1A Auto and they had parts available at half the price I installed and create a product works 100% no problems at all! They will now be my first choice for any auto parts. I also ordered from them a year previously as I couldnt find a water pump for an old vehicle They had it at a quarter of the price! I cant say it enough If youre looking for parts Theres no better place. Trevor
Little advice
December 22, 2018
I ordered fuel injectors for a suburban. I got them in a timely manner. When i went to instal them i had a little difficulty doing so. Then when i took them off i broke two of them. I called and they sent me out the two i broke at no charge. So the advice is if you order them check your o-rings to make sure they are the right size. But over all i had a great experience and i will definitely order from them again.
Cheap parts that work flawless ????
March 25, 2019
I bought a set of fuel injectors for a 5.3 Chevy...needless to say GM wanted 192 dollars for 1...I needed 8...so I jumped on 1A auto and bought a full set of 8 for 154 bucks...thats less for 8 than what GM wanted for 1...besides that 1A auto has a lifetime warranty on these particular parts how can you go wrong....long story short I will definitely be buying more parts from these guys again in the future!

Great product/Price. Excellent customer service. Thank You
September 8, 2019
I had a little trouble getting them to fit in my intake but I have had no problems since then.
Bad injectors
October 29, 2019
These were supposed to be for my Chevy 2500hd gas 6.0 installed one side. 2 ended up going bad in just a few days dumping massive amounts of fuel and throwing multiple codes so I ended up not using the other 4 out and bought injectors elsewhere
Value for the price
November 21, 2019
I purchase these injectors for my 99 Silverado. They were an exact match to the old ones. None of the injectors were damaged or damaged o rings. All were individually packaged. They arrived when they said it was supposed to and the price was the best for a full set compared to several other parts stores.
Works Great! 2000 5.3L Silverado
January 6, 2020
I used these injectors to replace all my injectors in my 2000 Silverado. They fit perfectly and went on with ease after a little dielectric grease was added to the o-rings. The price is great, the customer service is wonderful, and the product works great so far! I would recommend these and would buy these again if I needed to
Bad injectors, both banks running rich
February 13, 2020
After installing in my Silverado it ran rich from dumping excessive amounts of fuel, no error codes but my truck lacked power, was hard to start. Replaced them with OEM AC Delco fuel injectors and my truck runs awesome again!

Problems since day one
May 21, 2020
I put these on my engine and had nothing but problems with them. I replaced them for OEM ones and all my problems were solved. These injectors are not at all recommended.
Exactly what I ordered
August 15, 2020
Product fits perfectly. We will find out if everything works in the near future. My project is being worked on when I have the time. 69 C10 with a Vortec 5.3L setup. Thank you
Bad quality
September 5, 2020
The company is amazing! Customer service is amazing! The quality of the injectors were awful. Didnt work and made my truck worse than my bad injectors. Numerous cylinders were missing. Luckily I was granted a full refund.
Mix matched parts
September 23, 2020
Sent me 7 injectors of one style and one different one. The odd one out ended up being a close fit but by the time I realized it, I went to pull the fuel rail off and it pulled the end cap off of the injector which should have never come off in the first place( tried removing end caps from the old injectors, did not want to come off no matter what I tried) and then fell down in the intake port on the head. Ended up having to pull the intake for no reason. Hate to leave bad reviews but dont send mix matched parts especially if that one part ends up causing a huge issue other than the odd one out the other 7 work good.
Suburban injectors
October 2, 2020
shipping & price was great. However, when it came time to install the injectors, 1 of them was missing the black plastic tip on it. My mechanic had to use the black plastic tip off of 1 of the injectors he removed which 3 days later caused a leak in my truck and caused a fire in the engine bay. Thank God I was at a Goodyear tire service center who where able to extinguished the fire.
Great price
December 23, 2020
Installed in my vortec 6.0 over a month ago. Working great and improved gas mileage
One bad injector
March 24, 2021
I had one bad injector out of 8. I picked the best looking injector out of my old ones to finish my truck.
Great product
June 2, 2021
Direct fit and functioned perfectly. The owner was really surprised on how much more power the truck had
Buy good ones elsewhere - these are kinda different

September 5, 2021
Order Confirmation: 2DQL15XHVBE Full disclosure: I bought 8 of these injectors 4 years ago. They remained sealed and still new. I finally got to working on my 2002 Suburban. I ended up having leaky injectors and both banks are running real rich. I have no idea what brand these are but I am buying new ones elsewhere. I am forced to spend more money. The o-ring is located higher up on these. I don't like that from a seal perspective. These also have 4 injector holes in stead of 2. These are just different.
September 8, 2021
I haven't installed them as of yet. Weather they correct my problem or not remains to be seen. However, either way you look at it, a new set of injectors can't hurt. Stay tuned, I'll keep you informed.

are these 4 port sprayer? and do you have reprogram you computer in order to use them? 2004 silverado 5.3l(not flex)
July 7, 2021
You do not need to reset your computer after changing the injectors, though it is a good idea to do so. You will need the 8th VIN Digit to confirm fit on your vehicle. Be sure to verify all of the information shown in the Vehicle Fit tab before ordering.
July 8, 2021
Cristina P
I have a 03 Silverado with the 6.0 and I believe it has the 2 hole are these a 2 hole or a 4 hole thanks?
August 10, 2021
John D
The hole count is just a variation of nozzle tip, it will not effect the way the injectors fit or function.
