Jeep Cold Air Intakes

On the trail, a sealed / closed-box intake (like Volant PowerCore or S&B) keeps dust and water crossings out of your filter — the smarter pick for a Jeep that actually wheels. An open filter (K&N, Injen) trades some protection for the most airflow and the loudest induction note — great for a street/overland Jeep that rarely sees deep water.

Oiled cotton filters (K&N) flow the most air but need occasional cleaning and re-oiling, and over-oiling can foul a MAF sensor. Dry filters are lower-maintenance and more forgiving. Both massively outlast a paper factory filter.

For a bolt-on cold air intake on the 3.6L, no — it's a direct-fit upgrade. A tune only becomes worthwhile once you start stacking mods (intake + exhaust + throttle body).

If you're in California or an emissions-check county, confirm the specific kit carries a CARB EO number — many Jeep intakes are 50-state legal, but not all. It's listed on each product page.

Modest on its own — a few hp and a bit of torque on the 3.6L — but the throttle response and sound gains are immediate. Bigger power comes when it's paired with a tune and exhaust.

No. The JK (2007–2018) and JL (2018+) have different engine bays and airbox routing. Always buy by generation.

Sealed/closed-box for dust and water crossings; open filter for a street or overland build where sound and max airflow matter more.

Oiled (K&N) for max airflow if you'll maintain it; dry for lower maintenance. Both beat the factory paper filter.

Not for a bolt-on CAI on the 3.6L. Consider one if you're stacking multiple mods.

Some carry a CARB EO number (50-state legal), some don't — check the individual product page before ordering.
