Stinger® System, 4.0L
4.0L 6-CYL WRANGLER
Stinger is an engineered power system for Jeep street and off-road applications. With its free-breathing Banks Ram-Air® Intake and Monster® Exhaust upgrades, Stinger liberates 4.0L Jeeps from airflow restrictions, improving engine efficiency, durability and fuel economy while increasing power. The exhaust note is authoritative, yet civil, and includes a polished-stainless tailpipe tip.
Banks Ram-Air® Intake System 4.0L
4.0L 6-CYL WRANGLER
Banks Ram-Air Intake System replaces the factory's flat panel filter with a large conical lifetime filter that provides maximum high-flow filtration. The Ram-Air's opening is over twice as big as stock's, and without the 90-degree detours that choke airflow and kill power. The huge inlet, enclosed housing and much larger tubing reduce restrictions, dramatically improving airflow to the cylinders.
The results are impressive: Banks Ram-Air Intake more than doubles the factory intake's airflow, improving the Jeep's power and fuel economy. And Banks Ram-Air is designed to accommodate engine movement, which prevents component damage for reliable service life.
Monster® Exhaust 4.0L (Black Tip)
4.0L WRANGLER: Constructed entirely of heavy-gauge stainless steel, Banks Monster features a supersized, 2.5-inch tailpipe with a stainless tailpipe tip polished to a mirror finish. Banks Monster muffler, its straight-through performance muffler, is the industry's least restrictive. In comparison tests, Banks muffler flowed 501.2 cfm at 1 psi—a 140% improvement over the stock exhaust's 208.6 cfm, and about 44% better than the nearest competitor.
Monster virtually eliminates backpressure from the catalytic converter back, for more power and efficiency—and an authoritative, yet civil, exhaust note. For maximum results, combine with Banks TorqueTube® system.
Includes: Stainless Monster muffler; Stainless 2.5" tailpipe; Polished stainless tailpipe tip; Mounting hardware.
