The Lexus ISF K&N drop-in filter should be one of your first ISF upgrades! This is a proven upgrade that gains power and helps unleash the ISF's V8 engine intake sound! We highly suggest keeping the stock plastic intake box because it does not suffer as badly from heat soak as other after market metal tube units. Below is a list of features for K&N drop-in filters.
