aFe Momentum GT Cold Air Intake Pro DRY S Jeep Wrangler JL & Gladiator JT V6 3.6L | 51-76217

Overview

The aFe Momentum GT Cold Air Intake System with Pro DRY S Filter (Part #51-76217) is an engineered, bolt-on performance upgrade purpose-built for the 2018–2026 Jeep Wrangler JL and 2020–2026 Gladiator JT equipped with the 3.6L Pentastar V6. Designed for Jeep owners who demand real-world performance gains without sacrificing off-road capability, this sealed cold air intake delivers up to +12 horsepower, +12 lb-ft of torque, and 39% greater airflow over the restrictive factory intake. Whether you're crawling trails or cruising the highway, the aFe Momentum GT is widely regarded as one of the best cold air intakes for the Jeep Wrangler JL.

Key Features & Benefits

• +12 HP & +12 lb-ft Torque Max Gains – CAD-designed and dyno-tuned specifically for the 3.6L Pentastar, delivering measurable power improvements across the RPM range.
• 39% Increased Airflow Over Factory – The oversized intake path dramatically outflows the OEM airbox, reducing restriction and boosting throttle response.
• One-Piece Roto-Molded Sealed Housing – Custom computer-designed cross-linked polyethylene housing eliminates the need for multiple components, keeping intake air cooler and intake charge temperatures lower.
• Maintains Factory Water Fording Height – The sealed housing is engineered to retain the same water fording capability as the stock intake system, so you don't sacrifice trail confidence.
• Built-In Sight Window – A clear inspection window lets you visually check filter condition without removing the airbox — perfect for trail-side maintenance checks.
• Pro DRY S 3-Layer Synthetic Filter (5" x 8") – The massive 5-inch round flange, 8-inch tall, inverted-top conical filter uses progressively finer porosity synthetic media. No oil required — ever.
• Built-In Resonance Chambers – Integrated acoustic chambers in the intake tube manage and reduce unwanted intake drone, balancing performance sound with cabin comfort.
• Patent-Pending Filter-to-Housing Interface – Unique interface design maximizes usable filter volume while simplifying installation and filter swaps.
• Premium Stainless Steel T-Bolt Clamps – Corrosion-resistant hardware ensures a leak-free, long-lasting seal in all weather and off-road conditions.
• 50-State Legal – CARB EO# D-550-50 – Fully compliant with California Air Resources Board regulations. Legal for street use in all 50 states.
• No Tune Required – Plug-and-play performance. The Wrangler JL's ECU adapts automatically — no additional tuning or programming needed.
• 2-Year Limited Warranty – Backed by aFe Power's manufacturer warranty for peace of mind.
