K&N Drop In Air Filter Lexus IS250 / IS350 2006-2013
It has undergone a complete facelift and internal reworking. K&N Engineering has designed a filter (33-2345) to fit in the factory air box of the 2006 Lexus IS 350 3.5L V6 and the 2006 Lexus IS 240 2.5L V6. The drop-in design means adding performance is simple; just remove the disposable air filter in the Lexus IS 350 or IS 250 and replace it with a K&N Replacement Air Filter.
The washable, reusable, high flow flat panel filter is designed to increase horsepower and acceleration, while providing excellent filtration. The 33-2345 is 1 inch in height (25mm) with an outside length of 9.563 inches (243mm) and an outside width of 9.313 inches (237mm).
Unlike disposable filters, K&N Air Filters use a unique pleated design comprised of an oiled cotton fabric sandwiched between two layers of epoxy-coated aluminum screen. The filters capture airborne dirt particles while allowing high volume air flow. These particles then cling to the outside of the filter and become part of the filtering media.
