6.7L Powerstroke Intercooler Piping Kit: What It Does and How to Pick One
The 6.7L Powerstroke in the 2011–2022 Ford F-250 and F-350 Super Duty is a capable diesel platform, but the factory intercooler charge piping has a known limitation: it uses plastic and rubber components in the charge air path that are fine at stock boost levels and start causing problems the moment you add more fuel, tune it, or push the engine harder.
An intercooler piping kit replaces the factory plastic and rubber charge pipes with aluminum tubes and reinforced silicone couplers. Here’s what that actually changes and how to pick the right kit for your 6.7.
What the Intercooler Piping Does on a 6.7 Powerstroke
Your 6.7’s turbocharger compresses intake air, which exits the turbo hot and under pressure. That compressed air travels through the intercooler (mounted in front of the radiator) to get cooled down, then flows through the charge pipes to the intake manifold.
The intercooler piping kit covers:
- Hot side pipe: turbo outlet → intercooler inlet
- Cold side pipe: intercooler outlet → intake manifold
- Couplers: silicone connecting sleeves at each joint
- Clamps: stainless worm-gear or T-bolt clamps securing each coupler
On the factory 6.7, the cold side pipe in particular uses a plastic elbow that is prone to micro-cracking under heat cycling. When it cracks — and it will crack on a tuned engine — you lose boost pressure into the intake tract. The symptom is a pop-and-whistle sound under boost and sluggish acceleration that gets worse over time.
What You Actually Gain From a Piping Kit
Aluminum charge piping on a 6.7 Powerstroke delivers three real improvements:
1. Eliminated boost leaks. Silicone couplers over aluminum pipes hold 20–30 psi without the fatigue cracking that affects plastic elbows. This is the primary reason to upgrade — a tuned engine leaking boost through a cracked plastic pipe is wasting every dollar you spent on the tune.
2. Reduced heat soak. Aluminum conducts heat away from the charge air faster than plastic. In stop-and-go traffic after a hard run, the charge pipes cool more quickly, which helps the intercooler recover faster.
3. Improved flow. Quality aftermarket kits are designed with tighter bend radii and smoother internal surfaces than the factory plastic pieces, reducing restriction in the charge air path. The gains are modest on a stock engine — more meaningful on a tuned engine moving 30+ pounds of boost.
What to Look For in a 6.7 Powerstroke Intercooler Pipe Kit
Aluminum wall thickness: 0.063" (16-gauge) is the minimum for street/tow use. Thicker is better for competition builds or sustained high-boost applications.
Silicone coupler ply count: 3-ply reinforced silicone handles 35–40 psi without blowoff. 4-ply is worth the premium on built engines.
T-bolt vs. worm-gear clamps: T-bolt clamps apply even clamping force around the full circumference of the coupler. Worm-gear (hose) clamps are cheaper but can cut into silicone under vibration. Go T-bolt on every joint.
Fitment generation: The 6.7 Powerstroke changed significantly between 2011–2014 (Gen 1) and 2015–2022 (Gen 2/3). Confirm the kit is spec’d for your model year — especially the hot side, which changed geometry between generations.
Powder coat vs. bare aluminum: Powder coat protects against corrosion in the underhood environment. Bare aluminum is fine but will oxidize over time. Either works; it’s a cosmetic preference.
The FAS Motorsports 6.7 Powerstroke Piping Kit
FAS Motorsports produces a direct-fit intercooler piping kit for the 2020+ 6.7L Powerstroke. It’s built from 3mm-wall 6061 aluminum, ships with 4-ply reinforced silicone couplers, and uses T-bolt clamps on every joint.

It’s a direct bolt-on — no fabrication, no cutting existing lines. Install time for someone who’s done it once is under two hours.
When to Upgrade
You don’t need an intercooler pipe kit on a completely stock, untuned 6.7. The factory plastic holds up at stock boost levels.
Upgrade immediately if any of these apply:
- You’ve added an EGR delete, DPF delete, or tune that increases boost
- You’re pulling heavy loads (over 15,000 lb GVW) regularly — the sustained boost cycles accelerate plastic fatigue
- You’ve heard a pop or hiss under acceleration that wasn’t there before (boost leak diagnosis)
- You’re building toward compound turbos or a big single turbo upgrade
Fuel and tune upgrades are wasted money if the charge piping can’t hold the boost those mods generate. The piping kit should come before — or alongside — any power adder on the 6.7.
Summary
The 6.7 Powerstroke intercooler piping kit is a simple, durable upgrade that eliminates a known failure point on the factory charge air system. For any 6.7 that’s been tuned or towed hard, it’s as important as an upgraded fuel filter or coolant filter — maintenance that pays for itself the first time it prevents a boost leak on the interstate.
