My Summit Racing catalog confirms that that is the correct part number for Ford Racing 24#/hr injectors. BTW: Summit Racings everyday price is $315.95

Re: i need to know if these injectors ARE RIGHT want to buy tonight
Yes, they'll work just fine.
Basically the two issues you're going to run into are:
1.) Height. These injectors a just a tad shorter than stock, but O-ring to O-ring, they're the same. So long as you use the clips to mount them properly to the fuel rail, the slightly shorter length will be in the manifold, and it will cause NO PROBLEMS. ....if you DON'T use the clips at the fuel rail, the shorter length could potentially cause them to work themselves down into the manifold, and they could unseal from the fuel rail. They won't come out, but they could leak. Again, if you use the clips, you'll be fine. If I'm not mistaken, Accell's factory replacement GM/TPI injectors are shorter too. Myself, and so many others are using these Ford/Bosch injectors with no problems.
2.) the slightly higher fuel rating. Stockers being 22, your new 24s are going to dump a little more fuel. There are threads and threads and threads about exactly what will and will not happen, and the bottom line is there's still no absolute definitive answer. You can do two things, burn/buy a chip with the correct injector value, or don't. ...myself, and a "most" of us who've done this have a reburned chip, and of course, no problems. If you don't, well, technically it's not the best way to go, but several people have done this with no chip, and haven't had any issues. I ran with the stock chip for several weeks with no issues. Bottom line for ME, is to leave no doubt as to proper operation, and that meant having a chip burned. Cost me $200 via mail order, but I also took care of a lot of little things, had some performance changes made, and if I ever choose to have the car tuned on the Dyno, that $200 will go towards the cost. For me, a no brainer.
When I did the swap to these injectors, I also installed an adjustable fuel pressure regulator. Ultimately though, I've pretty much got it set back to STOCK pressure!!!

Re: i need to know if these injectors ARE RIGHT want to buy tonight
22# are hard to find.
I can't speak as to the difference between good and bad Accells, but I personally would steer clear, based on what I've read.
I paid $199 + shipping for the injectors, and $200 for the chip. To me, $400 was an acceptable cost for new injectors, PLUS a few tweaks to the chip as well!

Re: i need to know if these injectors ARE RIGHT want to buy tonight
I strongly recommend an adjustable fuel pressure regulator (AFPR) to go along with new injectors, it's a very handy tuning tool. And of course, you will need a good fuel pressure gauge.
Also, stay away from the Accels, they are junk according to many on this board. (see, I can read also)
The ECM can make about a 16% adjustment in fueling. The Ford Racing injectors are about 9% bigger, so you should be just fine in drivibility. However, you might run a bit rich at wide open throotle (WOT). Thats where the AFPR comes in.
And BTW: the Ford injectors are a bit shorter, just like abubaca said (he is a genius and modest), make sure you use the clips that fit into the very small grooves in the top of the injectors. If I remember correctly, there are two grooves, you will want to use the upper one. And when you install the injector, put a little bit of oil on your finger tip and oil up the orings.

Wow you guys are awesome blows my mind the wealth of knowledge you guys can retain... Well i got the info i needed i am going to buy the 24# bosch injectors off ebay and use the money i save for a good gauge and FPR...lol. you guys will love this...any suggestions on where to get a good deal on a good FPR and pressure gauge?

Re: i need to know if these injectors ARE RIGHT want to buy tonight
I bought my BBK AFPR at Summit for about $70 bucks. Maybe it was $80. Anyhow, most of them are about that price. I think Crane has a more expensive one, but it's the whole regulator, where as the others are essentially just the cap, diaphragm and adjuster screw which mount on your current reg. Unless yours is shot, this should be plenty. Assuming your TPI is already disassembled for the injector swap anyhow, the AFPR itself can be swapped in less than 30 minutes. Shoot, less than 10 once you've done it once or twice!
As for a gauge, I bought a fancy schmancy aftermarket gauge that mounts directly to the fuel rail, looks trick, and is great for talking about when the hood is popped at the local cruise in. For YEARS however, I used a gauge I bought at Autozone. It has about 18" of tubing between the schraeder valve connector and the gauge itself, so you can mount it and tape the gauge to the windshield for real time driving fuel pressure measurements. HUGELY valuable if the need ever comes up. It also had a pressure bleed off tube, so you can releive any built up fuel pressure before unhooking any fuel lines. Again, HUGELY valuable when the time comes. I think I paid less than $20.
BTW......4 more posts to 4000!!! Woohoo!!! I feel like a little kid!!!!! .....and you mentioned retaining knowledge? Shoot, I've been here for about 10 years, and felt the need to post 4000 times. You can't begin to imagine how much I've read and learned. I could barely change my own oil when I bought my car. 3 Years ago I pulled the heads and did a ZZ4 cam swap with hand tools and Thirdgen.Org. I've swapped two automatic transmissions, a rear end, rebuilt the ENTIRE suspension, replaced the entire interior, and am rebuilding a T5 now.

Re: i need to know if these injectors ARE RIGHT want to buy tonight
Thanks for the compliment, but after 13 years of doing this stuff, I should be smarter. It appears that you are just getting started, dont give up. There is alot of good stuff on thirdgen. Go thru many of the Technical articles, you can reach them from the home page here.
