This is a Bosch CIS USA 930 fuel head modified by CIS Flowtech for sale.
CISFLOWTECH
I have 2 of them and one is on my car. They work great.
I tried this one for a week or so and it works perfectly and it is like new.
It is rebuilt and modified to flow more fuel than a stock USA fuel head or euro fuel head for running higher boost and making more horsepower safely with good AFR's.
If you have a stock USA 930 fuel head and have it modified the cost is ~ $550 plus shipping both ways and you don't have your origonal stock USA lambda fuel head anymore.
Buy this very low use rebuilt and modified 930 fuel head for $500 plus shipping and you save money and you still have your origonal 930 fuel head to keep or sell to recoup some cash.
