Cold Air Intake Kit for 1997-2006 Jeep Wrangler TJ 4.0L / 2.4L / 2.5L

Flashark Cold Air Intake Kit for 1997–2006 Jeep Wrangler TJ — 76mm Aluminum, Dry Filter, Heat Shield

The 4.0L AMC straight-six is a legend, but the factory airbox is an afterthought. Flat plastic housing, paper filter choked with trail dust, and hot under-hood air everywhere the Wrangler goes off-road. This Flashark cold air intake fixes it.

A full 76mm mandrel-bent aluminum tube replaces the factory snorkel. The dry, reusable cone filter sits in a sealed heat shield that blocks engine bay heat and keeps water splash out of the intake. A 3/4-inch heat-wrap line runs the full length of the tube, keeping intake temps down during long climbs and summer crawls.

No tune. No CEL. No cutting. Bolt it on in about an hour and feel the throttle sharpen right where you need it — 2,000–4,000 RPM on the trail.
