Flashark Cold Air Intake Kit for 2012-2016 Jeep Grand Cherokee SRT 6.4L V8 (392 HEMI)
If you drive a 2012-2016 Jeep Grand Cherokee SRT, the 6.4L 392 HEMI pulls air through a factory airbox built around noise and vibration targets rather than flow. This Flashark cold air intake replaces the factory intake plumbing with a mandrel-bent 101mm (4-inch) 6061-T6 aluminum tube, a sealed steel heat shield, and a 6.5-inch conical dry filter that draws from the fender well. Your factory MAF sensor mounts into a CNC-machined housing, so the stock ECU calibration stays in place and no tuning is required. Everything bolts to factory mounting points with basic hand tools, with no cutting, welding, or drilling.

Key Features
- 101mm (4.0") 6061-T6 aluminum intake tube: A one-piece mandrel-bent tube with no step-downs or reducers, sized to match the 392 HEMI throttle body inlet.
- 6.5" conical dry filter: Washable and reusable with no oil to apply — because it runs dry, there is no filter oil that can migrate onto the MAF sensor — and its large surface area supports airflow at high rpm.
- Sealed steel heat shield: Shields the filter from engine-bay radiant heat and routes the intake to cooler fender-well air, holding intake temperatures approximately 20-35°F below stock under load.
- CNC-machined 101mm MAF housing: Your factory MAF sensor mounts into a housing machined for the 392 HEMI, so the kit runs on the stock ECU calibration and no tune is required.
- Multi-layer silicone couplers: Black heat-resistant couplers with stainless T-bolt clamps at every joint for a leak-free seal.
- Bolt-on installation: 100% factory mounting points with no cutting, welding, or drilling — a 60-90 minute install with basic hand tools.
- Deeper HEMI intake tone: A noticeably deeper intake note under acceleration that settles down at highway cruise.
Who This Kit Is For
Who is this kit for? This Flashark cold air intake replaces the factory intake plumbing on the 2012-2016 Jeep Grand Cherokee SRT 6.4L V8 (392 HEMI) on the WK2 platform. It is built for SRT owners who want fender-well air instead of engine-bay air, a washable dry filter instead of disposable paper, and a bolt-on install that keeps the factory MAF sensor and ECU calibration.
For you if… you drive a 2012, 2013, 2014, 2015, or 2016 Grand Cherokee SRT and want a first bolt-on breathing upgrade · you would rather clean and reuse a filter than buy paper elements · you want the factory MAF sensor and the factory drive modes left alone · you are comfortable with a 60-90 minute install on factory mounting points · you have checked your own state emissions rules in the Compliance Notice below.
Not for you if… your Grand Cherokee runs the 3.6L V6, the 5.7L HEMI, the 3.0L EcoDiesel, or you drive a Trackhawk with the 6.2L supercharged engine · you are shopping for a drop-in paper air filter rather than a full intake kit · better fuel economy is your main goal · you need an EO-exempt part for street use in a CARB-adopting state · you cross deep water regularly.

Check Before Ordering
- Vehicle fitment: Exact fit for the 2012-2016 Jeep Grand Cherokee SRT with the 6.4L V8 (392 HEMI, WK2). It does not fit the Grand Cherokee 3.6L V6, 5.7L HEMI, 3.0L EcoDiesel, or Trackhawk (6.2L supercharged). Not sure which engine you have? Message us with your VIN before ordering.
- Intake type: A cold air intake with a sealed steel heat shield that routes the filter to fender-well air rather than open engine-bay air.
- Filter: Dry, washable, and reusable — no oil and no re-oil kit involved. Clean the element, let it dry fully, and refit it.
- Sensors and calibration: The kit includes a CNC-machined 101mm MAF housing; your factory MAF sensor is reused, the stock ECU calibration is retained, and no tune is required.
- Legality: Not legal for sale or use in California (and other CARB-adopting states). See the Compliance Notice below for the full statement.
- Install and water: Bolt-on at factory mounting points, roughly 60-90 minutes with basic hand tools. Avoid deep water crossings — water ingestion can cause hydrolock and severe engine damage.
