Does it fit a 2020-2027 Frontier with the 3.8L V6?

Yes. It is made for the 2020-2027 Frontier 3.8L V6 and is stated to work on trucks with Auto Start/Stop.

Will it add horsepower?

Expect only a small gain at best. Most of the change owners notice is sound and throttle response, not dyno-proven power.

No tune is required. The mass airflow sensor reads the higher airflow, but a tune is only needed if you want to extract more from other mods.

Yes. It is a washable, oiled cone filter, so clean and re-oil it instead of buying paper elements.

Yes, mainly under hard acceleration. Cruising noise stays close to stock.

The intake tube, cone filter, couplers and clamps, plus mounting hardware. Confirm the kit contents before ordering.
