Important
What to Know Before You Buy
Cold Air vs Short Ram
A cold air intake draws air from outside the engine bay (fenderwell, grille) for cooler, denser air and better power. A short ram intake stays under the hood; easier install and lower cost, but can pull warmer air. For maximum gains, cold air is preferred.
Filter Maintenance
Oiled filters need periodic cleaning and re-oiling. Dry filters (SynthaMax, S&B Dry Extendable) are maintenance-free longer. Choose based on preference; both flow well when maintained.
Engine-Specific Fitment
The JL Wrangler has multiple engines: 2.0L Turbo, 3.6L V6, 3.0L EcoDiesel, and 6.4L 392 Hemi (Rubicon 392). Each requires a different intake. Verify fitment for your engine before buying.
Water Fording
Jeep Wranglers are built for off-road. If you frequently water ford, ensure your intake is sealed or positioned to avoid hydrolock. Most enclosed systems protect the filter from splash and dust.

Common Questions
Frequently Asked Questions
Do I need a tune when installing a cold air intake?
Most cold air intakes are plug-and-play; no tune required. The factory MAF sensor and ECU handle the increased airflow. For heavily modified engines, a tune can optimize gains. Check the product listing for manufacturer notes.
Will a cold air intake void my warranty?
Bolt-on intakes generally do not void the vehicle warranty. They do not alter emissions equipment. Some dealers may flag modifications; check with your dealer if concerned. Magnusson-Moss Warranty Act protects against blanket voiding.
I have a Rubicon 392. What intakes fit?
The 6.4L 392 Hemi in the Rubicon 392 (2021–2025) requires a specific intake. S&B and other brands offer 392-specific kits. Check our air intake collection and filter by vehicle for the latest 392 fitment.
Do the same intakes fit the Gladiator?
Many JL intakes also fit the Gladiator JT 3.6L (2020–2025), since both share the same engine. The Banks Ram-Air and Flowmaster Premium in this guide fit both. Always verify fitment before buying.
