Note: S\u0026amp;S breather valves come with elongated breather holes to increase the duration of the vacuum; allowing more oil to be drawn from the cylinder heads. This has no disadvantage in any model year; either stock or Big Inch motor.  Note: A +.030\"oversize breather is available to save worn or damaged crankcases as 531236. A JIMS breather hole reamer (MCS 978343) will ream the damaged hole to +.030\" so a +.030\" breather can be used.\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 36-47 Big Twin (NU)\u003c\/p\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":54307903045959,"sku":"531233","price":239.28,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/7812\/0519\/files\/531233k.jpg?v=1784484129","url":"https:\/\/www.chopperessentials.com\/products\/s-s-steel-breather-valve-spacer-set-std-36-47-big-twin-nu","provider":"Chopper Essentials Co.","version":"1.0","type":"link"}
