The Rugged Ridge cold air intake for 2.4L 2003–2006 Jeep Wrangler TJ swaps the factory airbox for a polished mandrel‑bent aluminum tube and heat shield, feeding a high‑flow dry panel filter that never needs oiling. The bolt‑on, no‑drill installation improves throttle response and can raise fuel economy, but this specific kit is not compatible with vehicles equipped with air conditioning.
