Is the AEM 21-8128DC worth it for a 2017 Sentra?

It is worth it if you want more intake sound and a washable filter. The 17 hp gain is modest and mostly felt at higher rpm, so do not expect a big seat-of-the-pants change.

Does it fit other Sentra years or engines?

No. This kit is listed for the 2017 Sentra with the 1.8L four-cylinder. Check the part number for other model years or the 1.6L turbo.

Do I need to oil the filter?

No. The Dryflow filter is synthetic and washable, and it does not use oil. Clean it with AEM cleaner and let it dry before reinstalling.

Will it void my warranty or fail emissions?

AEM states the kit is legal for street use in most states, but check your local emissions rules. Warranty coverage depends on your dealer and the Magnuson-Moss Act.

Prices on intake kits tend to dip during holiday sales and at the end of the model year. Compare across stores before buying.
