The distinctive blue casing, period-correct shape, and Bosch quality made it the OE choice for VW and the long-standing first call for restorers ever since. For a numbers-correct restoration of a 1967 or later 12V Beetle, Karmann Ghia, Type 3, or Bus, the Bosch Blue is the right coil.\u003c\/p\u003e\n\n\u003cp\u003eThis version is the modern epoxy-filled production — sealed, durable, and mount-in-any-orientation.

Both are 12V German-brand 3.4–3.5 ohm coils. Bosch was the OE supplier on VW; Beru is also period-correct on many German cars. Either is correct for a restored air-cooled VW.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBosch Blue vs Bosch Black — which is better?\u003c\/strong\u003e\u003cbr\u003e\nFor numbers-correct restorations, the Blue is the period-correct choice. The Black is a newer high-energy design with slightly hotter spark; it's the better choice for a daily-driven or performance application where modern-spec ignition is welcome.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I mount it upside down?\u003c\/strong\u003e\u003cbr\u003e\nYes. This is an epoxy-filled coil — no orientation restrictions. Mount in any position.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this the same coil that came on my 1973 Beetle from the factory?\u003c\/strong\u003e\u003cbr\u003e\nFunctionally identical. The original 1973 factory coils were oil-filled rather than epoxy-filled, but the modern Bosch Blue is the direct replacement and uses the same housing color, mounting pattern, and electrical specs.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's the bracket for?\u003c\/strong\u003e\u003cbr\u003e\nThe bracket mounts the coil to the engine fan shroud (on most air-cooled VWs) or to the firewall (on some installations). The included bracket matches the factory Bosch mounting pattern.\u003c\/p\u003e","brand":"Washburn's Metal","offers":[{"title":"Default Title","offer_id":44474449330291,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/2760\/1523\/files\/00-9409-B-500x425.jpg?v=1774324957","url":"https:\/\/shop.washburnsmetal.com\/products\/bosch-blue-coil-with-bracket-12-volt-blue","provider":"Washburn's Metal","version":"1.0","type":"link"}
