It sits directly in the factory airbox in place of the standard paper filter no modification required. Unlike a disposable paper filter, the K\u0026amp;N cotton gauze design flows more air into the engine while maintaining effective filtration, and can be cleaned and re-oiled rather than replaced at every service interval.\u003c\/p\u003e\n\u003cdiv class=\"wl-pull\"\u003eThe 350Z's VQ35DE is a free-revving naturally aspirated V6 that responds well to improvements in intake airflow.
