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

    Can this be used with the IAG V3 Top Feed Fuel Rails without need for specialty fittings or additional hardware?
  • Q: stock fuel rails  Ken2 years ago

    are the included fittings plug and play for the 2008 STI stock fuel rails?
