ACDelcoGM Original Equipment 17113698 Multi-Port Fuel Injector

Best price on GMC spec injectors. Replaced 12 yr old set on a 2005 Denali GMC Yukon. Brought new life to engine. A few u-tubes and I was ready to tackle this. I was getting too lean faults while pulling trailer. Suspected restricted injectors after study of engine fault codes. Apparently under heavy load motor was starved for fuel and ECM could not compensate. Was doubtful; cleaning would be the answer due to age of units.Not cheap but its the heart of engine performance. For the DIY shade tree mechanic Amazon rules for auto parts.

It is what it says it is, and works as it should. Those two things are harder to come by than they should be.

This product shows that there's a blue O-ring in the picture on the bottom of this injector, but when I received the injector in the mail it had a brown O-ring on the bottom instead of the blue O-ring showing in the picture description. Seller said it would still work because the part number fit my vehicle so I put them on my vehicle anyway because I didn't want to go to the hassle of returning them. I don't know why the sellers don't show a picture of the actual part that's being shipped. Me personally I just don't like being misled by a picture on Amazon. The original GM part I changed had Blue O-rings on the bottom of the injectors and I thought I was getting a product that fit the description in the picture. The Injectors worked OK I just don't like putting something on my vehicle that's different from the original part which is what I thought I was getting.

This price is less than half of what the local parts store wanted for the same injector. This injector comes in a bag with an AC Delco 17113698 sticker on it. The injector its self has 25317628 printed on the side of it. Looking around on the internet indicate that both numbers are completely interchangeable. An engine with bad injectors, is an engine that is wasting gas! I would rather pay for the injectors and have a good running engine than to pay more often at the pump.

This is a carton of 1. At this price, I expected 8..

I tried the cheap $50 set of 8 injectors when I was broke. They caused all kinds of random misfires and bank 1 was adding 18% fuel all the time. They even plugged a converter. I bought and installed 8 two days ago and long term fuel Trims are back to 0 most all the time. If you actually need injectors buy these, don’t cheap out! It will only cause you grief.

Normally I go with AC Delco as replacement parts in my Hummer because they are OEM and they just work.... Well not this time. My originals were still working fine at 300K miles but figured I'd replace them all while doing some other work.After replacement the engine ran very rough at idle. Took it into shop to get a diagnosis done. Turned out 2 of the 8 were significantly low on pressure. Cost more to have the shop fix things than all 8 cost me originally.

Price is too high
