Your factory wiring was designed for a stock alternator — upgrading to 1\/0 gauge copper wiring on the three main power and ground cables ensures your new alternator can deliver its full rated output safely and efficiently. Without it, you are leaving power on the table and putting unnecessary strain on your factory wiring.\u003c\/p\u003e","brand":"JS Alternators","offers":[{"title":"250 amp alternator","offer_id":53861194727796,"sku":"11340-370Z-2010-2020-3.7L-250-adp6003-9801-325-s7","price":469.0,"currency_code":"USD","in_stock":true},{"title":"320 amp alternator","offer_id":53861194760564,"sku":"11340-370Z-2010-2020-3.7L-320-adp6003-9801-325-s7","price":517.0,"currency_code":"USD","in_stock":true},{"title":"370 amp alternator","offer_id":53861194793332,"sku":"11340-370Z-2010-2020-3.7L-370-adp6003-9801-325-s7","price":569.0,"currency_code":"USD","in_stock":true},{"title":"400 amp alternator","offer_id":53861194826100,"sku":"11340-370Z-2010-2020-3.7L-400-adp6003-9801-325-s7","price":639.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/2300\/1972\/files\/11052-6003-angle_97649e2a-f85e-4cde-812c-10d460647980.png?v=1776101671","url":"https:\/\/jsi-racing.com\/products\/2009-2020-nissan-370z-v6-3-7l-high-output-alternator","provider":"JSI Racing","version":"1.0","type":"link"}
