Cold Air Intake for 1999-2004 Jeep Grand Cherokee WJ V8 4.7L CAI

Flashark Cold Air Intake for 99-04 Jeep Grand Cherokee WJ V8 W/Heat Shield

Jeep gave the WJ Grand Cherokee a torquey 4.7L PowerTech V8, then shoved its voice through a plastic airbox maze designed to kill every decibel. What you got was a quiet, strangled V8 that sounded more like a vacuum cleaner than a Jeep.

The Flashark cold air intake replaces that restrictive factory maze with a mandrel-bent T-6063 aluminum intake pipe finished in black powder coat for heat and corrosion resistance. The included heat shield helps insulate the open-element dry performance filter from engine-bay heat, while the system retains the factory lower fresh-air inlet to draw cooler air from the fender well. Your 4.7L breathes with less restriction, throttle response sharpens, and — most importantly — the engine finally sounds like the V8 it is.

Installation takes 45–75 minutes with basic hand tools. The kit is a direct bolt-on: all couplers, clamps, and hardware are included. No cutting, no drilling, no permanent modifications. Expect 5–10 WHP on an otherwise stock engine, with potential for 10–15 WHP when paired with headers and a tune. But honestly? Most WJ owners buy this for the sound — and it delivers from the first throttle blip.

Key Features

Mandel-bent T-6063 aluminum intake tube with black powder-coated finish — resists under-hood heat and corrosion, won't rust or flake

High-flow dry performance air filter — no oil required, washable and reusable, won't contaminate the MAF sensor

Powder-coated steel heat shield — separates the filter from radiator and exhaust manifold, radiant heat for cooler intake air

Retains factory lower cold-air inlet — draws from the fender well, not just the hot engine bay

Direct bolt-on installation — all silicone couplers, stainless steel clamps, and mounting hardware included; 45–75 minutes

5–10 WHP gain (stock engine) — 10–15 WHP when combined with headers, exhaust, and a tune

Throttle response improvement — reduced intake restriction means the 4.7L responds faster to pedal input

Wakes up the PowerTech V8 — deep induction growl under load, clean and subtle at cruise
