A cold air intake improves how freely the engine draws air. K&N's NextGen is simpler than a full boxed intake: a direct-fit panel filter plus a modular intake tube, leaving more of the factory setup in place.
why this one — The headline +19 hp and +19 lb-ft is the biggest intake claim in this group, but K&N labels it estimated, meaning it comes off a flow bench rather than a dyno, so weigh it against Injen's and aFe's smaller dyno-based numbers rather than taking it at face value. It is $99 cheaper than K&N's boxed Blackhawk and does name the Sierra 1500 as compatible. The source page is inconsistent on whether coverage ends in 2025 or 2026.
