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

🏁 392 HEMI. The Way It Was Meant to Breathe.

The 392 HEMI in your Grand Cherokee SRT is a proper American V8 — 470 horsepower, 470 lb-ft of torque, and a soundtrack that nothing else touches.

But the factory intake system? It's built to muffle that engine, meet emissions targets, and keep noise complaints down in the suburbs.

Flashark's 101mm cold air intake strips all of that away:

→ 101mm smooth-bore aluminum tubing — straight-sh

ot airflow to the 392
→ Oversized dry filter replaces the tiny factory paper element
→ Intake temps drop 20-35°F under load
→ That HEMI induction roar you can actually hear at WOT
→ No tune required
→ Direct bolt-on in 90 minutes

The 392 HEMI was built to breathe big. Flashark gives it room to.

Why Flashark? 5 Reasons

1️⃣  101mm — RIGHT-SIZED FOR THE 392

The 392 HEMI displaces 6.4 liters. It needs a serious increase in air volume at WOT — the factory intake can't keep up.

Flashark's 101mm bore:
• Matches the 392's throttle body outlet
• Eliminates all factory flow restrictions
• Smooth-bore aluminum — no turbulence
• MAF sensor reads cleanly — no CEL

→ More air where the HEMI wants it most: full throttle, high RPM

2️⃣  DRY FILTER — PERFECT FOR A DAILY SRT
The Grand Cherokee SRT is a daily driver that also happens to do 0-60 in 4.4s.

Flashark's dry media filter:
• No oiling — no mess on your hands
• Wash and reuse, no re-oiling
• 6.5" XL cone = massive flow capacity
• Zero risk of over-oiling the MAF sensor
• Better fine-particle filtration than traditional cotton-oiled filters

3️⃣  COLD AIR — NOT HOT ENGINE BAY AIR
The 392 runs hot. The SRT's engine bay is densely packaged — heat soaks everything quickly.

Flashark's heat shield enclosure:
• Seals the filter from radiant heat
• Draws cooler air from the fender well
• Keeps intake temps down even after repeated hard pulls
• Full enclosure — no hot spots

Denser air = more power. Physics wins.

4️⃣  NO TUNE REQUIRED
The 392 HEMI's factory ECU is well- calibrated and adaptive. Flashark's precision MAF housing gives your ECU exactly the airflow data it expects.

→ No check engine light
→ No tune needed for daily street use
→ Works on stock or tuned ECUs
→ SRT Drive Mode system unaffected

5️⃣  BOLT-ON IN 90 MINUTES
Designed specifically for the 2012-2016 Grand Cherokee SRT platform. Everything fits the first time.
