The K&N 33-2286 is a washable, reusable panel filter built for the 5.6L V8 in Nissan Titan and Armada trucks and SUVs. Its layered, pre-oiled cotton gauze media is K&N's High-Flow design, which the manufacturer says is meant to raise airflow while still trapping contaminants that could harm the engine. Compared with a stock paper element, the main purchase case is longevity. The manufacturer says a cleaning every 75,000 miles of normal highway driving is enough, so one filter can replace a series of disposables. Each unit also carries K&N's No-Hassle Lifetime Limited Warranty, subject to the stated limitations.
Shoppers searching for a K&N 33-2286 Nissan Titan 5.6L V8 drop-in air filter, a reusable Armada intake filter, or a pre-oiled cotton gauze replacement will find this part sized to the factory airbox, at 11.375 x 9.625 x 1 inches. The manufacturer describes it as a drop-in unit that fits the stock box without modification. Fitment years are not consistent across sources, so confirm the application for your specific year and trim before ordering. For the install, most owners only need to swap the stock element. Per the manufacturer's installation hints, some K&N filters must be seated in the airbox lid first, the clips take more pressure than a factory foam seal, and the box should not bend under that pressure. Disconnecting the intake tube can make the lid easier to handle.
The manufacturer states that the filter generally needs cleaning about every 75,000 miles under normal highway driving conditions.
Yes. The manufacturer says the filter is pre-oiled and ready to drop into the factory airbox, so no separate oiling step is needed before installation.
The manufacturer's application listing for Titan and Armada shows 2004 through 2010 for this fitment range, but other listings show wider years. Confirm your exact year, model, and engine against the manufacturer's fitment guide before ordering.
This is a drop-in swap with no cutting or modification, so most owners can handle it with basic hand tools. Remove the stock element, wipe out the airbox, and check that the new filter sits in the lid groove as the manufacturer describes. If the filter does not seat cleanly, reinstall the lid and try again rather than forcing it. Do not overtighten the clips or screws, because a misaligned lid can crack the airbox. If the lid is hard to maneuver, disconnect the intake tube first. Keep any loose clips or hardware in a safe place, since losing them can prevent the airbox from sealing properly.
