It removes the factory PCV system, a well-known failure point, and is designed to run with an external catch can system.\u003c\/p\u003e\u003cp\u003eThree -12 ORB\/AN ports provide efficient evacuation of crankcase pressure, which becomes increasingly important on high-boost builds and can help reduce valve train instability such as exhaust cam timing drift (\"VANOS walk\").\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e This item is supplied on a pre-order basis. The factory PCV system is removed, so an external catch can system is required – the catch can, hoses and lines are not included. Supplied with two -12AN swivel fittings, one -12 ORB\/AN block-off fitting and one 1\/8\" NPT plug. The cover uses genuine BMW gaskets, which are available from any BMW parts supplier.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCNC machined from a single block of 6061-T6 aluminium to minimise leak paths\u003c\/li\u003e\n\u003cli\u003eThree -12 ORB\/AN crankcase ventilation ports (third port allows future expansion)\u003c\/li\u003e\n\u003cli\u003eInternally blocks the factory PCV intake ports – no external plugs required and less carbon build-up on the intake valves\u003c\/li\u003e\n\u003cli\u003eMachined ignition coil dust seals to keep debris out of the spark plug wells\u003c\/li\u003e\n\u003cli\u003eInternal baffling for improved oil control at high RPM and high load\u003c\/li\u003e\n\u003cli\u003eIntegrated 1\/8\" NPT port for a crankcase pressure sensor\u003c\/li\u003e\n\u003cli\u003eCompatible with BM3, MHD and standalone ECU crankcase pressure monitoring and fail-safe strategies\u003c\/li\u003e\n\u003cli\u003eUses OEM BMW gaskets for easy long-term servicing\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBMW G20 M340i (B58 Gen2)\u003c\/li\u003e\n\u003cli\u003eBMW G22 \/ G23 M440i (B58 Gen2)\u003c\/li\u003e\n\u003cli\u003eBMW G42 M240i (B58 Gen2)\u003c\/li\u003e\n\u003cli\u003eBMW G29 Z4 M40i (B58 Gen2)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NRW","offers":[{"title":"Default Title","offer_id":55702413115768,"sku":"NRW-G2B58VC","price":3794.7,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0765\/4670\/3651\/files\/nrw-design-billet-valve-cover-bmw-g20-m340i-g22-g23-m440i-g42-m240i-g29-z4-m40i-b58-gen2-1848009.jpg?v=1792039414","url":"https:\/\/www.evolveautomotive.co.uk\/products\/nrw-design-billet-valve-cover-bmw-g20-m340i-g22-g23-m440i-g42-m240i-g29-z4-m40i-b58-gen2","provider":"Evolve Automotive","version":"1.0","type":"link"}
