    Received fast via regular shipping so you can only imagine expedited shipping! FPR is good and not too bad of an install. EJ owners should definitely consider this cobb fpr for that stumble fix.

    • Q: This or the $300 FPR  Eulises6 months ago

      I am planning on getting the Cobb Flex fuel kit in the fall. Will this FPR be ok to run for now with my oem setup or do I go with the FPR that's $300. Dont want to buy a FPR twice in the future due to my setup. TY Rallysport!!

        A:  Hi, the $300 kit is intended for use with a more stock fuel rail. You'll be fine with this one for your future plans.

    • Q: difference  Frosty2 years ago

      so what is the difference between this and the 300 dollar cobb fpr kit? do they both fit and do the exact same thing?

        A:  This kit is meant to work with Cobb's fuel lines and rails, the other kit is meant to be used with an otherwise stock setup.
