    Great product 3 years ago
    5out of 5stars

    overall great product all the fittings are nice the lines are kind of stiff I've worked with some that are easier to maneuver. could have definitely made my own for almost have the cost but the piece of mind of the great cobb products was enough for me to order and install with my IAG TGV's and fuel rails. Install was a little tougher than some other installs wish i would have gotten them when i built my engine to ease everything. Intake manifold must be removed. These are -6AN lines

    • Q: Fully compatible with IAG V3 Fuel Top Feed Rails?  thaiboxer7 months ago

      Can this be used with the IAG V3 Top Feed Fuel Rails without need for specialty fittings or additional hardware?

        A:  The IAG rails are -8 AN, these are -6 AN. Cobb makes a fuel rail with -6 AN fittings, and IAG makes fuel line kits with -8 AN fittings.
