The K&N 33-5017 is a washable, reusable panel element built for the factory air box on the 2014 Toyota Tundra 4.6L and 5.7L V8 and the 2014 Sequoia 5.7L V8. K&N's High-Flow Air Filters use a layered, oiled cotton media designed to improve airflow and capture contaminants. Compared with a disposable paper panel, you pay more up front but skip repeat purchases, since the filter is engineered to last for the entire lifespan of your vehicle and is backed by K&N's lifetime limited warranty. Owners on user forums say it performs well for on-road driving, though one discussion reports dirt getting past a K&N during heavy off-road use, so off-road drivers should inspect it more often.
Search terms this filter answers include 2014 Tundra 5.7L washable air filter, 4.6L V8 drop-in panel filter, Sequoia 5.7 cotton gauze intake filter, and K&N 33-5017 horsepower upgrade. K&N drop-in replacement filters are designed to install easily into your factory air box. Because the filter is a direct swap, you keep the stock intake tube and housing, which preserves the factory warranty and avoids the cost of an intake kit.
The manufacturer's Tundra application covers the 4.6L and 5.7L V8 models from 2014 through 2017, and the Sequoia application is the 5.7L V8. Fitment for later model years differs across sources, so confirm your exact year and engine with the manufacturer before ordering.
The manufacturer's product page states cleaning every 75,000 miles under normal highway driving, while the manufacturer's Tundra guidance cites 50,000 miles. Details vary, so confirm the interval with the manufacturer and check the filter sooner if you drive on dusty roads.
No. The manufacturer designs the filter to fit the stock air box without modification, so it is a direct swap for the factory paper element.
Per the manufacturer's listed specs, this is an easy, drop-in job that typically takes 5 to 10 minutes and needs only a screwdriver to open the air box. Start by removing the air box lid and the old paper element, then seat the K&N panel in the base. Some K&N filters must go into the lid first, so hold the new element in place with your fingers while you reinstall the lid. Make sure every lid tab is fully seated in its slot, since an unseated tab can let the box pop open while driving. On hinged air boxes, a light coat of filter grease or silicone spray on the sealing surface reduces friction when closing the lid. Before you finish, confirm the lid seals evenly to keep unfiltered air from bypassing the element.
