In stock and limited—order today! The PLM Billet Valve Cover for Honda B-Series engines (B18, B20, B16) is here, made possible by overwhelming feedback from our Instagram followers. After months of meticulous design and programming, our prototype is nearly ready for test fitment. Follow us on social media @PrivateLabelMfg for updates! Starting with a precise scan of the OEM cover, we achieved measurements accurate to 0.005", then redesigned it with a baffle system and optional dual AN10 ports for easy installation of an oil catch can or air-oil separator. We also included an integrated circular cut-out design, allowing cam timing adjustments without removing the cover. Buy the original PLM for the best in quality and design!
