Fitment & Compatibility

The aFe Momentum GT 50-70080D is a vehicle-specific fit, designed exclusively for:

• 2021–2026 Jeep Wrangler Unlimited Rubicon 392 (JL) — V8 6.4L HEMI

Important fitment note: This intake is engineered specifically for the 392 (6.4L V8) variant of the Wrangler JL. It is not compatible with 2.0L or 3.6L Wrangler engines. The sealed housing integrates with the factory hood inlet scoop and retains the 392's HydroGuide water-separation system, making it suitable for light water crossings when used as directed. Always verify your year, make, model, and engine before ordering.

Cross-Reference / OEM Reference: Replaces factory Jeep Wrangler 392 (JL) air intake/filter assembly. Companion wet-filter variant: aFe 50-70080R (Pro 5R Media).

Installation

Installation is rated intermediate difficulty with an estimated time of 2–6 hours. Common tools required include a socket set, screwdriver set, and torque wrench. The Momentum GT's innovative one-piece housing and reduced part count make this a more straightforward installation than traditional multi-piece systems — no cutting or drilling of OEM parts required, and no ECU tune is needed post-install. Professional installation is optional but recommended for those less experienced with engine bay work. Refer to the included aFe POWER instruction sheet or the official installation guide at afepower.com for step-by-step guidance.
