If you are adapting a 3-bolt DBC throttle body up to 75mm onto a 4-bolt LS2\/LS3 intake and want a precision, long-lasting connection, this kit is a practical choice. If your project uses an LS4 intake or a 3-bolt drive-by-wire throttle body, look for a compatibility-specific alternative.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this adapter fit my LS3 intake?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—compatible with many LS3 4-bolt intakes when the throttle bore is within 92mm and the throttle body is a 3-bolt DBC up to 75mm.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this on a drive-by-wire throttle body?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No—this kit is not compatible with 3-bolt drive-by-wire throttle bodies or LS4 intake manifolds.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Eiahonen","offers":[{"title":"Default Title","offer_id":48084387823774,"sku":"B0DLJVFRT8","price":31.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/eiahonen-front-view-adapter-kit.jpg?v=1785853044","url":"https:\/\/northtrailauto.ca\/products\/eiahonen-ls-drive-by-cable-throttle-body-adapter-kit-3-bolt-to-4-bolt-t6-cnc-aluminum-fits-up-to-75mm","provider":"North Trail Auto","version":"1.0","type":"link"}
