Cold Air Intake for 1997-2006 Jeep Wrangler TJ

TJ owners know the drill: the 2.5L and 2.4L AMC/PowerTech four-cylinders have the torque to crawl, but the factory intake chokes them on the road — especially at highway speed or with bigger tires pushing the wind. This Flashark kit swaps the restrictive stock airbox for a Φ76 mm heat-insulated aluminum tube and a high-flow red dry filter that keeps charge temps down even when the 4.0L's exhaust manifold is baking the engine bay next door.

The tube itself is wrapped — not just painted — with a thermal insulation layer that actively rejects radiant heat from the exhaust side. Couple that with the oversized dry cotton filter and you get better throttle response, a throatier induction note, and a cleaner engine bay — all for under a hundred bucks.

Key Features

• Φ76 mm Heat-Insulated Aluminum Intake Tube — Wrapped tube with integrated thermal barrier rejects underhood radiant heat. Mandrel-bent for smooth airflow to the throttle body
• High-Flow Dry Cotton Gauze Filter — Red conical filter: chrome-plated steel upper cap 120 mm / PU lower cap 180 mm / 76 mm inlet with dedicated clamp. Washable, reusable, no oiling ever required
• Precision Reducer Coupler — Φ63 × Φ76 mm silicone reducer transitions cleanly from the intake tube to the factory throttle body inlet
• Breather Hose Included — Reinforced D19-d13 × 175 mm hose with Φ10 breather nipple, direct match to factory PCV routing on both 2.5L AMC and 2.4L PowerTech engines
• Complete Mounting Hardware — Copper-bushed aluminum anchor mount (M6), anti-vibration foam strip (560 mm), 2× stainless narrow-band clamps (84×108 mm), and all M6 fasteners
• Bolt-On Installation — Uses factory airbox mounting points on TJ chassis. No cutting, no welding, reversible in under 60 minutes
• No Check Engine Light — Maintains correct MAF/IAT sensor positioning and factory breather routing on naturally aspirated 2.5L and 2.4L applications
