This Stage 2 cold air intake system for the Ford Super Duty with the Power Stroke 6.7L produces 26hp, 80lbs. x ft. torque and outflows the factory intake by 67%. This system is enclosed in a durable 16 gauge, powder-coated heat shield; this air intake filter features a washable/reusable inverted cone conical air filter with Pro5R/7 oiled media that improves airflow for increased horsepower and torque. Also available is the Pro Dry S which supports similar power and airflow figures but is easy to replace.
This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance.
Additional Information: One-piece heat shield requires little or no assembly and utilizes factory mounting points for easy, no-cutting or drilling installation. The 5 and 7 series filters are constructed with 100% polyurethane for long life and multiple cleaning cycles.

Absolutely love this mod
Can finally hear my turbo! If you have a tuner and this intake your truck will moooove. I have a non deleted 2016 6.7 with a superchips tuner and this intake added a bunch of extra power and it pulls all the way through 60 so it doesn't stop now

Love the speed and price
Used on a Ford F350 6.7l Diesel Dually. Spooling is a bit quicker and turbo whine is slightly louder though not as loud as a stock 11-14. Install was quick and easy with the help of some window cleaner on all the joints where the boots would need to slide back and forth on the install. Shipping was amazingly fast but that's because the order was shipped from the manufacturer that is only a couple towns from me. Best price I could find on the internet. Very happy

1 QUESTION
Is there a replacement filter available for purchase in the pro guard 7 media? I'm currently running the ats aurora 4,000 drop in turbo kit, have cleaned my filter religiously every 15,000 miles (all highway I believe in the instructions it says to service every 30k depending upon driving conditions) and have collapsed my filter is it recommended that I move up to a no limit fab 5"" or is this intake sufficient for my modified turbo setup and I can simply replace the filter??
Yes replacement filters are available. Part number 72-91051. For 91.00. Have to special order from AFE.
