The K&N 33-2713 is a High-Flow Original Lifetime replacement engine air filter for the 3.0L fuel-injected V6 in the Acura NSX. It is a panel-style element made from cotton gauze, so it swaps in for the stock paper filter without changing the airbox layout. The main reason to choose it over a disposable filter is that it can be washed and reused, which turns a recurring filter purchase into a one-time buy for most of the car's life.
Against a stock paper element, K&N states that this filter is built for higher airflow while still maintaining filtration levels meant to protect the engine over time, and the manufacturer rates its filtration efficiency at up to 99%. No horsepower figure was confirmed for this part, so the value case rests on airflow, filtration, and reusability rather than a quoted power gain. Buyers searching for a washable Acura NSX 3.0L V6 air filter, a reusable NSX drop-in high-flow filter, or a cotton gauze NSX intake filter will find this is the standard K&N option for that engine. Because the element is washable, follow the manufacturer's cleaning and re-oiling instructions and let it dry fully before reinstalling it.
The manufacturer lists this filter as washable and made of cotton gauze. Use the manufacturer's cleaning and re-oiling instructions when servicing it.
The manufacturer lists fitment for the Acura NSX V6-3.0L fuel-injected engine across 1991–2005. The product title for this listing reads 1991–96, so confirm the year range with the manufacturer before ordering.
The manufacturer's listing cross-references Beck/Arnley 0421793 and Carquest 88823. Compare these against your existing filter's part number before purchase.
