The 3.6L Pentastar V6 in your 2018-2024 Jeep Wrangler JL or Gladiator JT is a proven powerplant — but the factory airbox suffocates it with a narrow, sound-tuned intake tract designed for cabin quietness, not performance. The Flashark Cold Air Intake Kit replaces that restrictive stock assembly with a smooth 3-inch (76mm) mandrel-bent aluminum tube, a high-flow dry cotton gauze filter, and a sealed heat shield that draws cooler, denser air from outside the engine bay.

The result is an estimated 7-10% horsepower gain (20-29 HP) and 5-7% more torque (13-18 lb-ft), with noticeably sharper throttle response and a deeper intake growl under acceleration. The black powder-coated finish resists under-hood heat and corrosion, while the dry filter eliminates the messy oiling process and MAF sensor contamination risk common with oiled filters on the Pentastar platform. Bolt-on installation takes about 30-45 minutes with basic hand tools — no cutting, no drilling, no tune, no check engine lights.

⚠️ Note: This intake is designed for the 3.6L Pentastar V6 only. It does NOT fit the 2.0L turbo I4, 3.0L EcoDiesel V6, or 6.4L V8 (Rubicon 392) models. It also does NOT fit the 2012-2018 Wrangler JK — that is a different platform requiring a different intake kit (BQM0004005).

Key Features

3" (76mm) Mandrel-Bent Aluminum Tube — Smooth, unrestricted airflow path replaces the factory corrugated intake tube; black powder-coated finish for heat resistance and corrosion protection

Dry Cotton Gauze Filter — No Oil Required — High-flow washable dry filter element; no oiling means zero risk of MAF sensor contamination, a known issue with oiled filters on the 3.6L Pentastar V6

Sealed Heat Shield with Edge Trim — Isolates the filter from engine-bay heat, pulling cooler, denser air for consistent power delivery; black edge trim ensures a tight seal against the hood liner

Estimated 7-10% Horsepower Gain (20-29 HP) — Based on stock 285 HP 3.6L Pentastar; eTorque-equipped models see similar gains; actual results vary with altitude, fuel quality, and vehicle condition

Estimated 5-7% Torque Gain (13-18 lb-ft) — Improved low-to-mid range torque for better crawling response off-road and smoother highway merging

Deeper Intake Growl — Replaces the muffled factory intake note with a more aggressive induction sound under load — noticeable under acceleration but quiet at idle and cruise

Washable & Reusable Filter — Clean every 15,000-20,000 miles (5,000-10,000 in dusty off-road conditions); saves money over disposable paper filters and reduces waste

Complete Bolt-On Kit — Includes all couplers, clamps, hardware, and installation guide; typical install time 30-45 minutes with basic hand tools; reversible to stock at any time

💡 Pro Tip: The Wrangler JL replaced the JK in 2018, and the Gladiator JT launched in 2020 on a stretched JL platform. Both share the same 3.6L Pentastar V6 and similar (but not identical to JK) engine bay layouts. The easiest way to confirm your model: JK Wranglers have round headlights; JL Wranglers have rectangular headlights with LED signature lighting. If you have a 2018 Wrangler, check your headlights to determine whether it's a late JK or an early JL.

Q: Will this intake fit my 2018 Jeep Wrangler — is it a JK or JL?

A: 2018 was a transition year — both the JK and JL were sold. The easiest way to tell: JK Wranglers have round headlights, while JL Wranglers have rectangular headlights with LED signature accents. This intake (BQM0004006) fits the JL only. If you have a 2018 JK, you need intake kit BQM0004005 instead. Check your headlights or VIN decoder to confirm before ordering.

Q: Will this fit the Jeep Gladiator as well?

A: Yes. The Gladiator JT (2020-2024) shares the same 3.6L Pentastar V6 engine and a very similar engine bay layout with the Wrangler JL. This intake kit fits both the Wrangler JL and Gladiator JT equipped with the 3.6L V6. All Gladiator 3.6L trims (Sport/Sport S, Overland, Rubicon, Mojave) are compatible.

Q: Do I need a tune after installing this cold air intake?

A: No tune is required. The Flashark CAI is designed to work within the factory ECU's adaptive range. The stock 3.6L Pentastar ECU will automatically adjust fuel trims to accommodate the increased airflow. You will not trigger a check engine light under normal driving conditions. If you already have a performance tune, this intake will complement it and may yield slightly higher gains.

Q: How much horsepower will I gain?

A: Based on the stock 285 HP output of the 3.6L Pentastar V6, you can expect an estimated 7-10% increase (approximately 20-29 HP) and 5-7% more torque (13-18 lb-ft). Actual gains depend on altitude, fuel quality, ambient temperature, vehicle condition, and whether you have other modifications. The most noticeable difference is improved throttle response — the 3.6L Pentastar tends to feel sluggish off the line, and this intake helps wake it up.

Q: Will this work with the eTorque mild hybrid system?

A: Yes. The eTorque system (48V belt-driven mild hybrid) is integrated into the accessory drive and does not modify the intake system. The 3.6L Pentastar with eTorque uses the same intake manifold, throttle body, and airbox as the non-eTorque version. This CAI is fully compatible with both standard and eTorque-equipped 3.6L Pentastar engines.

Q: Will this cause a check engine light (CEL)?

A: No. This intake is designed to work with the factory MAF sensor without modifying its housing or readings. The stock ECU adapts to the increased airflow within its trim range. If you do get a CEL after installation, it typically means a loose coupler or clamp is causing an unmetered air leak — double-check all connections and ensure the MAF sensor is properly seated and the electrical connector is fully engaged.

Q: Is the filter oiled or dry? Do I need to oil it?

A: The filter is a dry cotton gauze filter — no oil required. This is intentional: oiled filters can over-oil and contaminate the MAF sensor on the 3.6L Pentastar, causing rough idle, hesitation, and CEL codes. The dry filter provides the same high-flow performance without the oiling hassle or sensor risk. Simply wash with mild soap and water when cleaning is needed.

Q: How long does installation take?

A: Typical installation time is 30-45 minutes using basic hand tools (socket set, screwdriver, pliers). The kit is a direct bolt-on replacement for the factory airbox — no cutting, drilling, or permanent modifications required. The included instruction manual walks you through each step. Installation is fully reversible if you ever want to return to stock.

Q: Can I use this with a snorkel kit?

A: This intake is designed to replace the factory airbox in its stock location. It is not designed to integrate with a snorkel system . If you have a snorkel kit that replaces the factory airbox with a remote-mounted filter, this CAI would not be compatible. If your snorkel feeds into the stock airbox location, the sealed heat shield design may still work, but you should verify compatibility with your specific snorkel kit before purchasing.

Q: Does this intake affect fuel economy?

A: The intake itself does not directly change fuel economy. Some users report a 1-2 MPG improvement on the highway due to reduced pumping losses and more efficient combustion. However, if you find yourself driving more aggressively because of the improved throttle response and intake sound (which is very common!), you may see no change or even a slight decrease. Results vary by driving style.

Q: How often do I need to clean the filter?

A: We recommend cleaning the dry cotton gauze filter every 15,000-20,000 miles under normal driving conditions. If you frequently drive off-road, in dusty environments, or in heavy rain, clean it every 5,000-10,000 miles. Use a mild soap and water solution, rinse from the inside out, and let it air dry completely before reinstalling. No filter oil is needed — this is a dry filter.

Q: What is the warranty and return policy?

A: This product is covered by a 1-year warranty against manufacturing defects in materials and workmanship. We also offer a 30-day money-back guarantee — if you are not satisfied with your purchase, return it within 30 days for a full refund.
