Product Reviews

December 31, 2014 - Part 9742
I bought the 9799, 9705, 9742(Red) and 9772(Red) Cold Air intake set for a Coyote install. The parts arrived rapidly and the quality is unsurpassed. Note the part numbers 9742 and 9772. The 2 gets you the red version of the coupler tubes. This detail is not mentioned in the catalog. If you are buying this for a Factory Five Cobra, the filter FFR provides, is of course, the wrong filter, so you'll need to obtain the right part. I haven't done that yet, but Specter probably has it. This assembly looks beautiful on the front of your engine. Very happy.
