FITMENT

DESCRIPTION

Product Overview

• The Powerstroke diesel lineup is legendary for relentless torque and heavy hauling, but the factory airbox is the single biggest restriction in the intake path. The stock setup's sound-dampening baffles and narrow tubing choke the turbo, driving up intake temperatures and Exhaust Gas Temperatures (EGTs) when you're pulling heavy loads or climbing steep grades.
• The Performance Cold Air Intake System replaces the restrictive stock airbox with a smooth, mandrel-bent intake tube and a high-capacity dry filter that feeds the turbo with minimal pressure drop. The result is faster turbo spool, sharper throttle response, and cooler EGTs under load — exactly what a working diesel demands.

Key Features

• High-Flow Tubing: Replaces the restrictive factory intake pipe with a smooth, mandrel-bent tube that eliminates internal turbulence and maximizes CFM air volume into the turbo compressor.
  
• Washable High-Flow Dry Air Filter: Features a reusable, high-capacity dry synthetic filter that traps fine dust without oil — zero risk of oil vapor contaminating turbo components.
  
• Lower EGTs: Removes the restrictive stock airbox to reduce turbo workload, helping keep Exhaust Gas Temperatures in check under heavy towing and steep grades.
  
• Corrosion-Resistant Finish: Polished or black powder-coat (by kit) stands up to engine bay heat, road grime, and oxidation.
  
• Direct Bolt-On Fit: Mounts to existing factory locations with included bracket and hardware — no cutting, drilling, or ECU tuning required.

FAQ

Q: Why does a diesel respond so well to a cold air intake upgrade?

A: The turbo relies on efficient compressor inlet conditions to build boost cleanly. The stock airbox creates measurable inlet restriction, forcing the turbo to work harder and generate excess heat. Removing that restriction lets the turbo spool faster and run cooler.

Q: Will this help lower my EGTs when towing heavy?

A: Yes. Lower inlet restriction reduces turbo workload to hit target boost, which translates directly to lower exhaust drive pressure and cooler EGT readings under heavy towing or steep grade climbs.

Q: Is the dry filter safe for my turbo?

A: Absolutely. The 100% dry synthetic filter requires no oil, eliminating any risk of oil vapor being drawn onto the turbo compressor wheel while still offering high dust-holding capacity for job sites and dirt roads.

Q: Do I need a custom tune or chip after installation?

A: No. Each intake works on stock engine calibration, increasing air volume without altering critical sensor inputs — you can bolt it on and drive immediately.
