Unlock the Duratec 35 V6’s Potential: Red Cold Air Intake for 2013-2017 Ford Flex & Taurus
Who It’s For: Designed specifically for 2013-2017 Ford Flex and Ford Taurus owners running the naturally aspirated 3.5L Duratec V6 engine. If you’re looking for a reliable, noticeable boost in performance, a more engaging engine sound, and better throttle response without diving into an EcoBoost swap, this is your entry point.
The Problem: That factory airbox on your 3.5L Duratec V6 is a real cork. Ford designed it primarily for quiet operation and cost-efficiency, not for maximum airflow or spirited performance. From years of wrenching on these, I’ve seen firsthand how the restricted piping, convoluted air path, and standard paper filter choke the engine’s ability to breathe freely, especially when you really lean into the throttle. This limitation means your Duratec V6 isn’t reaching its full potential, leaving horsepower and torque on the table that you paid for.
The Solution: We engineered this cold air intake system to bypass those factory bottlenecks. By providing a direct, smooth path for colder, denser air directly to your engine and pairing it with a high-flow, oil-free filter, we’re allowing your 3.5L Duratec V6 to inhale deeply and efficiently. This isn’t just about bigger numbers; it’s about enhancing the driving experience. The result is a noticeable improvement in acceleration, a more aggressive and satisfying engine sound, and an immediate, sharper connection to the road you’ll feel every time you drive.
Why This is the Ultimate Upgrade
- Performance Gains You’ll Feel: Expect a real-world increase of 5-10 horsepower and 6-8 lb-ft of torque. More importantly, you’ll notice sharper throttle response and improved acceleration across the RPM range, making daily driving more dynamic and highway passing effortless.
- Engineered Durability & Easy Maintenance: Crafted with high-quality aluminum piping for optimal airflow and longevity, this kit includes a reusable, washable micro cotton gauze filter. This oil-free design ensures excellent filtration without the mess, saving you money on disposable filters and making maintenance a breeze.
- Seamless & Striking Integration: This system is a direct bolt-on replacement for your restrictive factory air box. Installation is straightforward, typically achievable within an hour using basic hand tools. Plus, the vibrant red piping gives your engine bay a clean, sporty, and custom aesthetic that truly stands out.

Installation & Tools
The Wrench Time
- Estimated Time: 45-60 Minutes
- Difficulty: 3/10 - Basic bolt-on upgrade, but requires patience with the delicate D3/D4 platform factory plastics.
Tools You Will Need
- 8mm socket (1/4-inch drive for clamps)
- 10mm socket (with a 6-inch extension)
- 10mm wrench (for battery terminals)
- T20 Torx driver (for MAF sensor)
- Small flathead screwdriver
- Panel popper tool
The 3.5L Cyclone V6 has a notorious weak point: the factory PCV breather hose connection on the intake tube. The gray/green locking tab gets baked by underhood heat and becomes incredibly brittle. Do not muscle it. Gently use a small flathead screwdriver to lift the tab just enough to clear the catch. If you snap it, you’re buying a whole new PCV routing harness from the dealership.
Phase 1: Removing the Factory Part
- Disconnect the Battery: Always start by disconnecting the negative battery terminal using a 10mm wrench to prevent check engine lights and clear the KAM (Keep Alive Memory) on your 2013-2017 Ford Flex Taurus 3.5L.
- Unplug the MAF Sensor: Slide the red locking tab backward, press down on the release clip, and disconnect the Mass Airflow Sensor plug. Carefully unclip the wiring harness from the side of the airbox using a panel popper.
- Release the PCV Breather: Following the pro-tip above, use a small flathead screwdriver to lift the locking tab and pull the PCV hose straight back off the factory intake tube. Tuck it safely out of the way.
- Loosen Throttle Body Clamps: Use an 8mm socket to loosen the hose clamp securing the factory corrugated rubber intake tube to the throttle body. Pull the tube free.
- Remove the Factory Airbox: Locate and remove the single hold-down bolt securing the lower airbox to the chassis using a 10mm socket and extension. Grab the entire airbox assembly and pull straight up to pop it out of its lower rubber mounting grommets.
Phase 2: Installing the Cold Air Intake for Ford Flex Taurus (2013-2017) 3.5L V6 Engine Red
- Transfer the MAF Sensor: Remove the factory MAF sensor from the OEM airbox using a T20 Torx driver. Pull it straight out without touching the delicate exposed sensor wires. Seat it into your new Red Cold Air Intake tube and lock it down using the supplied aftermarket hardware and a screwdriver.
- Mount the Heat Shield: Drop the new heat shield assembly into the engine bay, pressing its bottom mounting pegs firmly into the factory rubber grommets. Secure the top mounting point with the provided hardware using a 10mm socket.
- Install the Silicone Coupler: Slide the provided silicone coupler onto the throttle body. Secure the throttle body side with a hose clamp and tighten it down firmly with an 8mm socket. Slip a second loose clamp over the open end of the coupler.
- Seat the Intake Tube & Filter: Feed the red aluminum intake tube through the heat shield opening and push the opposite end fully into the throttle body coupler. Tighten down the remaining clamp with your 8mm socket. Slide the high-flow conical air filter onto the end of the tube inside the heat shield and tighten its clamp.
- Reconnect Lines and Power: Snap the factory PCV line onto the new intake tube’s aluminum fitting until it clicks. Plug the MAF sensor harness back in and push the red locking tab forward to engage it. Finally, reconnect the negative battery terminal with a 10mm wrench.
- Perform the ECU Relearn: Start the engine. Do not touch the gas pedal for at least 20 seconds. Let the vehicle idle so the ECU can properly adjust the air/fuel trims to the newly increased airflow.
