The PPE Zilla Intake Manifold & Turbo Inlet Kit (Polished - 315054030) eliminates the restrictive factory intake bridge and resonator bottlenecks on 2020–2026 Ford 6.7L Powerstroke engines, delivering 69% higher maximum airflow via 3.25-inch stainless steel hydroformed runners and a fully round 4-inch turbo inlet paired with a 100% dry-carbon airbox duct.

Engineered Airflow Dynamics and Show-Quality Mirror Finish

Engineered specifically for the 2020–2026 Ford Super Duty platform powered by the 6.7L Powerstroke V8 turbo diesel, the PPE Zilla system addresses the OEM cast aluminum intake bridge's severe flow restrictions. The factory manifold constricts down to under 2.5 inches in certain passages and places the EGR swirl port directly in the path of incoming air, generating turbulence and uneven cylinder charging.

PPE eliminates these design flaws by using 3.25-inch mandrel-bent stainless steel tubing with hydroformed runners that route direct, balanced airflow to both cylinder heads. The restrictive factory EGR swirl boss is removed and repositioned with an included redesigned stainless steel EGR crossover pipe. Complementing the manifold, the kit includes a true round 4-inch stainless steel turbo inlet and a 100% dry-carbon fiber airbox duct, discarding the factory plastic two-chamber resonator to reduce weight, eliminate turbulence, and enhance turbocharger spool acoustics.

Key Features & Benefits

• 69% Higher Maximum Flow: Optimizes internal runner geometry and internal volume to deliver a massive 69% increase in maximum flow rate over the stock intake bridge.
• 3.25-Inch Hydroformed Runners: Smooth, large-diameter 304 stainless steel tubing ensures balanced fresh air distribution to both cylinder heads under high boost pressures.
• Redesigned EGR Crossover Routing: Re-angles and relocates the EGR entry to eliminate the turbulent center-stream swirl boss found in factory castings.
• True 4-Inch Round Turbo Inlet: Replaces the OEM shape-shifting oval ducting with a consistent 4-inch round stainless steel tract to maximize compressor velocity and reduce drag.
• 100% Dry Carbon Fiber Duct: Ultra-lightweight, heat-soak resistant dry carbon airbox connection eliminates the factory twin-chamber plastic resonator.
• Show-Quality Polished Finish: Hand-polished mirror exterior delivers an eye-catching under-hood visual enhancement that resists corrosion and thermal discoloration.
• Heavy-Duty 5-Ply Silicone Couplers: Includes oil-resistant lined multi-layer silicone boots and stainless steel T-bolt clamps capable of holding elevated boost levels without blow-offs.
• OEM Sensor & Accessory Integration: Retains factory mounting geometry, dipstick tube brackets, coolant line clips, and factory MAP sensor location (including stock MAP shield compatibility).

Vehicle Fitment & Installation Notes

• 2020–2026 Ford F-250 Super Duty – 6.7L Powerstroke V8 Turbo Diesel (Standard & H.O.)
• 2020–2026 Ford F-350 Super Duty – 6.7L Powerstroke V8 Turbo Diesel (Standard & H.O.)
• 2020–2026 Ford F-450 Super Duty – 6.7L Powerstroke V8 Turbo Diesel (Standard & H.O.)
• 2020–2026 Ford F-550 Super Duty – 6.7L Powerstroke V8 Turbo Diesel (Standard & H.O.)
• Fits Model Years: 2020, 2021, 2022, 2023, 2024, 2025, 2026
• High-Output (H.O.) Requirement: Standard-output 6.7L models bolt right up with the included hardware. On 500 HP High-Output (H.O.) models, the PPE Turbo Coolant Line Relocation Kit (SKU 319010000) is required to provide necessary clearance around the redesigned turbo inlet tract.
• Installation Tip: Install the lower intake manifold gaskets and EGR pipe loosely first to align the 3.25-inch runner flanges square to the cylinder head mounting pads before final torquing.
