Product Description

The K&N E-2605-1 is a high-flow, washable and reusable engine air filter designed to replace stock paper filters on a range of older Toyota and Isuzu vehicles from the 1980s and 1990s - including 4Runner, Supra, MR2 and other compatible models. Its premium cotton-gauze media and oil treatment allow it to trap dust and contaminants effectively while improving airflow, which can lead to better throttle response, smoother acceleration and a small bump in horsepower compared to a standard filter.

Because it's reusable, E-2605-1 lowers long-term maintenance costs and reduces waste from disposable filters. Its conical, drop-in design means installation is straightforward with no need for custom modifications - simply remove the old filter and insert the K&N unit. This filter is ideal for owners restoring or maintaining older Toyota/Isuzu vehicles who want a mix of performance, durability and convenience.
