The PEX airbox construction shields the filter from engine heat while optimized cutouts allow additional airflow paths and produce a refined intake sound signature. A massive 7\"×7\" washable pleated cotton gauze filter provides outstanding filtration with minimal pressure drop and no replacement interval - simply wash and reinstall.\u003c\/p\u003e\n\u003cp\u003eThe complete system includes all OEM gaskets, nuts, bolts, and clamps for a straightforward bolt-on installation with no engine modifications required.
