aFe Momentum GT Cold Air Intake Pro 5R Filter Jeep Wrangler 392 JL | 50-70080R

Overview

The aFe Momentum GT Cold Air Intake System with Pro 5R Filter (#50-70080R) is a dyno-proven performance upgrade engineered specifically for the 2021–2026 Jeep Wrangler JL Rubicon 392 with the 6.4L V8 HEMI engine. Delivering gains of up to +15 horsepower and +23 lbs. x ft. of torque, this sealed cold air intake system replaces the restrictive factory air box with a high-flowing, closed housing design that feeds your 392 a constant charge of cooler, denser air — maximizing power, throttle response, and engine sound. Made in the USA by aFe Power, the Momentum GT is the definitive bolt-on intake upgrade for Wrangler 392 owners who demand real, measurable performance gains.

Key Features & Benefits

• Dyno-Proven +15 HP & +23 LB-FT TQ — Verified on the dyno; real-world gains you can feel immediately from the first throttle input.
• 520 CFM Airflow @ 7" H₂O — Outflows Factory Intake by 14% — Dramatically increases air volume over the OEM intake for improved combustion efficiency and power output.
• 8" Tall 360° Radial Flow Pro 5R Filter — The largest air filter possible in this application; the pre-oiled, five-layer progressively finer cotton gauze media delivers maximum airflow and superior engine protection, with extended service intervals thanks to its inverted top and massive surface area.
• Patent-Pending One-Piece XLPE Sealed Housing — Constructed from heat-resistant, heat-soak-resistant cross-linked polyethylene (XLPE), the smooth one-piece housing eliminates multiple housing joints, seals out hot underhood air, and integrates with the factory hood inlet scoop to retain OEM water-separating functionality.
• Dyno-Tuned Intake Tube — Computer-designed and dyno-optimized for maximum power gains with a perfect, vehicle-specific fit — no modification required.
• Large Clear Sight Window — Inspect your filter condition at a glance without removing or disassembling any part of the system.
• Premium Stainless-Steel T-Bolt Clamps & 2-Ply Silicone Coupler — Corrosion-resistant hardware provides a rock-solid seal at the throttle body for long-term durability.
• No ECU Tune Required — Plug-and-play performance; the system works with your factory ECU right out of the box.
• Washable & Reusable Filter — The Pro 5R filter is fully serviceable. Clean and re-oil it for a lifetime of high-performance filtration, eliminating the cost of disposable paper filters.
• Auxiliary Air Scoop Plug Included — A urethane plug is included for cold-weather environments where you want to block off the auxiliary air inlet scoop.
• Throatier Engine Note — Customers consistently report a more aggressive, satisfying intake sound at wide-open throttle compared to the muffled factory air box.
• Made in the USA — Designed, engineered, and manufactured by aFe Power in Corona, California since 1999.
