Banks Ram-Air Intake for 2018–2023 Jeep Wrangler 2.0L Turbo Adds 82% More Airflow
Everyone knows a turbo needs clean, cool air for an engine’s maximum performance. Sadly, the stock Jeep intake is so restrictive that performance is hampered, resulting in a driving experience that’s muted in both power and sound. The Banks Ram-Air intake for the 2018-2023 Jeep Wrangler 2.0L Turbo maximizes air density, horsepower, and sound. Hear an aggressive new induction growl from the Wrangler’s 2.0L turbo and feel more power under your right foot for your Jeep. Banks’ unique shape rams more air into the turbo, increasing air density and efficiency.
The Banks Ram-Air intake system ditches the traditional restrictive flat paper filter and baffled stock intake tube in favor of a high-flow conical element with a smooth flowing intake duct. Having the filter fully enclosed not only keeps power-robbing heat away, but it also prevents dirt and dust from clogging the filter prematurely. This is a Jeep after all, so you’re going to get dirty once in a while.
Available with a choice of oiled or dry filter, the Banks Big-Ass Filter offers 627 square inches of filtering surface area and increases air mass flow by a whopping 82% over stock. This massive surface area extends the duration between filter cleanings. The Banks filter continues to flow long after smaller competitive filters clog with dirt and debris.
Why Air Density Beats Volume on the Turbocharged 2.0L Hurricane-4
Turbocharged engines rely on air density—the mass of oxygen packed into every cubic foot—to generate torque. The factory Jeep intake chokes incoming air with a flat paper filter and restrictive plastic sound baffles. These internal baffles disrupt laminar airflow while the stock housing traps power-robbing radiant heat inside the engine bay.
The Banks Ram-Air system replaces those restrictions with an insulated cross-linked polyethylene housing and 3-inch smooth-flowing intake duct. It draws cool outside air through a generous 6.5-inch by 4.7-inch inlet, flowing 782 CFM at peak demand. Consequently, delivering 82 percent more mass airflow lowers intake temperatures and provides greater thermal headroom on hot trails. This denser charge air eliminates ignition timing retard, allowing the 2.0L turbo to spool noticeably faster. Owners of 2024 and newer Wrangler JL and 4xe models can also install the updated 2024+ Ram-Air system.
