bosch III injectors
Does anyone have them in your Vette and if so how do you like them ?Is there any hidden thing I should know about them ? I am about to put them in a 91 l98 . They are a little different then the OEM injectors does everything go smoothly as far leaks and fitting them in ?

I have them in my 89 coupe l98 love them. I usually don.t suggest only one vendor but ONLY use FIC they are the best and have customer service that is almost non-existent these days. You will find many threads and a sticky at the top of this forum.

Bosch III injectors are modified to fit the C4 Vettes Only from supporting vendor FIC www.fuelinjectorconnection.com.
If you buy the Bosch III injectors anywhere else, they will not fit the C4 Vette Correctly and will leak.

It isn't that the stock Multec injectors didn't 'work fine', they're just a bad design when compared to the Bosch III's and others. That and when you consider the original injectors have most likely been clogged over time meaning this bad design is now performing at only a % of its intent, upgrading to the Bosch was a no-brainer for me.

When i bought my car last year it had new Bosch 3's in my '93. Was not running right as I had poor mileageand exhaust was black as being overfueled. Talked to Jon and he knew immediately what the problem was and sent out new one's. The '93's have a different impedence value and the computer was not reading them. Put the correct ones in and my mileage jumped from 17 to over 30. Right now trying some new Bosch's and my 3's are stored for now. My goal is to maintain over 30 mpg. This morning I am at 28.6mpg and am playing around with different pressures. When I put the new ones in I set fuel pressure at 43 and got 22-24 mpg. boosted it to 55 and was getting around 30. That is with no vacuum. I am at 60psi with vacuum and getting the 28.5. will fill up tonight and readjust pressure down and see what happens. If I can't get over 30-34 mpg I will put 3's back in as I did get over 33 with them. The key of course is how heavy your foot is.
