Flashark Cold Air Intake for 2012-2016 Grand Cherokee SRT 6.4L V8

Flashark 4" Cold Air Intake Kit for 2012–2016 Jeep Grand Cherokee SRT 6.4L — 392 HEMI, 101mm Tube, Dry Filter

The 392 HEMI in your Grand Cherokee SRT breathes through a factory airbox built for NVH compliance, not 470 horsepower. At wide-open throttle, that intake strangles the 6.4L before it can reach its top end.

Flashark's 101mm (4-inch) cold air intake fixes the bottleneck. A full-diameter, mandrel-bent 6061-T6 aluminum tube replaces the restrictive factory plumbing. The massive 6.5-inch conical dry filter pulls ambient air from the fender well — the coldest zone in the WK2 engine bay — and keeps intake temps 20–35°F cooler than stock under hard pulls.

The CNC-machined MAF housing is calibrated to match the factory ECU, so all SRT drive modes — Auto, Sport, Track, Tow — work exactly as intended. No check engine light. No tune. Just the deep HEMI intake growl and instant throttle response this engine should've had from the factory.

Installation: 60–90 minutes, basic hand tools, every bracket and clamp included.
