aFe Rapid Induction Cold Air Intake Pro 5R Jeep Wrangler JL Gladiator JT 3.6L | 52-10008R

Overview

The aFe Rapid Induction Cold Air Intake System with Pro 5R Filter (52-10008R) is a bolt-on performance upgrade engineered specifically for the 2018–2026 Jeep Wrangler JL and 2020–2026 Gladiator JT with the 3.6L V6 Pentastar engine. Designed for Jeep owners who demand real-world power gains both on the street and on the trail, this system delivers up to +9 HP, +9 lbs. x ft. of torque, and outflows the factory intake by up to 38%—all without requiring any ECU tuning. Made in Corona, California, this is the best cold air intake for 2018–2026 Jeep Wrangler JL looking for a proven, dyno-tested upgrade.

Key Features & Benefits

• +9 HP / +9 lbs. x ft. Torque Max Gains – Dyno-tested, proven performance gains with up to 38% more airflow over the factory intake and a 345 CFM rating at 7" H₂O for maximum engine breathing.
• Pro 5R Oiled 5-Layer Cotton Gauze Filter – The included 7" tall conical air filter uses five layers of progressively finer pre-oiled cotton gauze media, delivering high filtration efficiency and superior airflow even when dirty—ideal for street and track use.
• XLPE Dyno-Tuned Intake Tube – The computer-designed, roto-molded intake tube is constructed from heat-soak resistant XLPE thermoplastic, maintaining a perfect fit using OE mounting points for a secure, rattle-free installation.
• 18-Gauge Steel Wrinkle-Black Heat Shield – The powder-coated one-piece top-mounted heat shield snaps directly onto the lower half of the factory airbox, isolating the filter from engine heat to keep incoming air cool and dense.
• Off-Road-Ready Mounting Design – Integrated slotted mounting tabs secure the intake tube to the radiator shroud while allowing for natural engine movement during off-road articulation, so your intake stays put on the trail.
• Retention Groove Filter Interface – The filter base locks securely onto the heat shield via a retention groove—no additional hardware, clamps, or tools required for filter seating.
• No Tuning Required – This intake system is fully plug-and-play with the Wrangler JL and Gladiator JT's factory ECU. No tune, programmer, or additional calibration needed after install.
• Washable & Reusable Filter – The Pro 5R filter is easily recharged using aFe's POWER CLEANER and blue air filter oil, making it a long-term investment over disposable paper filters.
• Enhanced Intake Sound – The open-element design delivers a more aggressive induction growl and throttle response compared to the restrictive factory airbox.
• Made in the USA – Designed, engineered, and manufactured in Corona, California by Advanced FLOW Engineering (aFe), a leader in performance air intake systems since 1999.
