Quadratec Hi-Volume Cold Air Kit for 97-06 Jeep Wrangler TJ & Unlimited

Much simpler installation vs. complete Cold-air intake kits

I can tell a huge difference using this product.

Worked well for my Jeep.
Is it really, "cold air"? Not according to my ScanGauge, but that's not really the point. For me, there was not an appreciable reduction in intake temperature. The 3D printed intake ring that replaces the 90* bend really opens up the air available to the factory box. I noticed some extra GO from a complete stop, cruising around town, and at highway speeds. I turn a little higher RPM due to deep gears (4.88/33") and this kit seemed to open things up a bit in those higher ranges. I used a WIX paper filter, super skeptical on oiled media filters. Too early to tell on MPG.
