One of my injectors is faulty. All are original and I plan to replace them with a new set. I use only premium octane without ethanol. My Vette is a 90 C4 LT1 with 50K miles. It's a weekend driver. What are the best injectors available today? What is the brand name, part number and PSI rating? Who is the best vendor to buy from? I live in Australia so I want to be sure that I order using the correct specs first time....Many thanks!

My vote is for FIC. I have tested his work before he got it and after to see that he is doing the tests and gets about the same results as I did on a flow bench and tested it after to see that he did the work after I got it back. A couple times he was verified and seems to pass. Injectors flowed what I found them before and after.
With the newer injectors, you have no need to keep buying pure fuel. We have a lot of ethanol around me and while it does reduce the available power and kill the injectors of old, it isn't a "night and day" difference unless you are racing and the ethanol doesn't hurt the injectors anymore. The old Multecs had fuel cool the coils and the ethanol would destroy the insulation so that was the issue.
Tks, I'll contact FIC. I want to buy all new injectors. I read some old Forum posts recommending Bosch 111s. Are they still the best available for the L98?.
I went with 2 due to the newer Bosch 3 are better technology injectors. they were $189/set of 8 for my LT1 but I grabbed a coupon code for 17% off so $154.
Many thanks for the photos and advice. I have ordered a set of Bosch 3, from FIC. I ordered 22 psi as this appears to be the GM rating for the L98 FIC have been also recommended by as the specialist vendor for injector and Bosch 3s appear to be the best injectors available at this time.
Many thanks to all members for their input.......Paul
For 22 psi a new set of Bosch 111s is $349.00 + delivery. Reman is $179.95 + delivery. My delivery was expensive @ $50.00 by USPS. This was the only delivery option they gave for international.
Injector prices vary depending upon your specs.. There are many selection options
Thanks. Are the reman injectors legit? Honestly didn’t know remans were readily available, but never researched into it. Still rocking original Multecs on my 93 so eventually they will need to be replaced

See post 3. I tested it before and after to make sure he wasn't fluffing up how bad they were and how good a job he did after. His report synced with my test bench at least twice.
