The K&N 33-2344 is a reusable panel-style engine air filter for the 3.3L V6 in the Toyota Highlander Hybrid. The manufacturer says it is designed for high air flow while maintaining filtration levels critical to ensure long engine life. Its cotton gauze element is oiled, so it is a different choice from the disposable paper filter that comes from the factory. Because the element is washable, you can clean and re-oil it at service intervals rather than buying a new filter each time, which helps offset the higher upfront price of about $63.
This filter suits owners who want a lasting replacement rather than another paper filter. The manufacturer lists the fitment as the Toyota Highlander Hybrid V6-3.3L F/I for 2006 through 2010. Searches for a 2006 Highlander Hybrid 3.3L V6 washable air filter or a reusable 33-2344 drop-in filter match this part. Confirm your exact submodel and year against the manufacturer's fitment guide before ordering, because some listings describe the filter differently. Mounting into the stock airbox is a straightforward swap for most owners who are comfortable with basic hand tools.
The manufacturer lists this filter for the Toyota Highlander Hybrid with the 3.3L V6 (F/I) from 2006 through 2010. Because the product title refers only to 2006, check your VIN or the manufacturer's fitment guide to confirm your exact application.
The manufacturer specifies that this filter is washable and carries a No-Hassle Lifetime Limited warranty. Follow the manufacturer's cleaning and re-oiling guidance so the filter keeps its performance and its warranty coverage.
