Rugged Ridge 17755.01 Throttle Body Spacer for YJ/TJ/XJ 2.5L & 4.0L

The Rugged Ridge 17755.01 is a throttle body spacer designed to fit 1991–2006 Jeep Wrangler YJ/TJ and Cherokee XJ models equipped with the 2.5 L or 4.0 L engine. It raises the throttle body about 1 inch above the intake manifold to help draw in cooler, denser air and increase airflow through the engine, which can support improved horsepower and torque when paired with other performance upgrades. The spacer is made from solid aluminum with a black anodized finish and features a large-bore design to encourage better air intake, while installing with basic hand tools and no drilling required. Because it alters the intake, this spacer is typically intended for off-road or racing use and may not be legal in California or states with similar emissions regulations.
