      Specs. Getting dense, cold air into your engine lets your Wrangler take a deep breath, as it were, and increases its power and performance – or in other words, its torque and horsepower. The Throttle Body Spacer by Rugged Ridge boosts engine aspiration strongly by lifting the throttle body 1 inch above the intake manifold. Cold air flows in through the large bore spacer to boost your Jeep's power. What's more, the spacer is a snap to install with hand tools and no drilling.

      Construction. Rugged Ridge's Throttle Body Spacer is made from solid aluminum, which is rust-proof and strong yet lightweight. It comes with all necessary hardware and features bolt-on installation with hand tools, which is completely drill-free and can be completed rapidly. The spacer adds a 1 inch lift to the throttle body above the intake manifold. It functions with both 2.5 liter and 4.0 liter engines of the appropriate model years. A 5 year limited warranty against defects is provided by the manufacturer.

      Application. This Rugged Ridge Throttle Body Spacer is specifically designed to be used on the 1991-2006 Wrangler YJ and TJ models equipped with the 2.5L or 4.0L engine.

        2 1999 - Blacktac115 Installation Time: Less than 1 Hour

        No felt gain, annoying squeak at certain throttle positions

        No instructions but easy to put on. The only thing you would need instructions for is the extra parts come for the different models. No real gain in power or feel economy, but there's an annoying noise coming from the throttlebody in certain positions.

        Throttle body spacer

        Bolts right up. No instructions but easy. Fits good. Very little improvement in power. Ok part but dont expect a big gain in power.
