Cast in manganese silicon aluminum bronze alloy, these guides outperform OEM cast iron guides by conducting heat away from the valve more efficiently, reducing friction along the valve stem, and resisting the corrosion and cracking that commonly develop in high-mileage or high-boost 7M cylinder heads.\u003c\/p\u003e\u003cp\u003e Each set covers all 12 intake valve positions on the 24-valve DOHC head and is CNC machined to tight tolerances for a consistent press-fit into factory guide bores. Professional installation and post-install honing to final stem clearance are required. For builders performing a full valvetrain refresh, BC3932 pairs directly with BC3933 exhaust guides and the complete Brian Crower stainless steel valve lineup for the 7M platform.\u003c\/p\u003e","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":53200077029695,"sku":"BRCBC3932","price":112.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/b84a9cb7-f32d-4104-a1e5-4dcf4b90198f-800_ae06e460-128d-4900-9962-d4e8ff60f24c.jpg?v=1779935798","url":"https:\/\/wcaperformance.com\/products\/brian-crower-valve-guides-toyota-7mgte-6-0mm-intake-quantity-of-12","provider":"WCA Performance","version":"1.0","type":"link"}
