{"title":"LS Drive-By-Wire Throttle Bodies","description":"\u003cp\u003e\u003cstrong\u003eShort answer:\u003c\/strong\u003e The best LS throttle body is the one sized to your intake manifold and your boost level, not the biggest one you can buy. Granatelli Motor Sports builds drive-by-wire LS throttle bodies from 103mm to 120mm. Each one plugs into the factory-style GM 6-pin connector and arrives as a complete assembly, so nothing moves over from your stock unit. On a stock-style LS3 intake or a boosted 6.2L, start with a 103mm. Step up to 105mm, 108mm, 112mm or 120mm when your manifold inlet and the rest of the combination can use the air.\u003c\/p\u003e\n\u003ch2\u003eShop LS Throttle Bodies by Size\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/c-1389394-throttle-bodies-gm-throttle-bodies-ls-103mm\"\u003e\u003cstrong\u003eLS 103mm\u003c\/strong\u003e\u003c\/a\u003e | \u003ca href=\"\/collections\/ls-105mm-throttle-bodies\"\u003e\u003cstrong\u003eLS 105mm\u003c\/strong\u003e\u003c\/a\u003e | \u003ca href=\"\/collections\/c-1389395-throttle-bodies-gm-throttle-bodies-ls-108mm\"\u003e\u003cstrong\u003eLS 108mm\u003c\/strong\u003e\u003c\/a\u003e | \u003ca href=\"\/collections\/c-1389421-throttle-bodies-gm-throttle-bodies-ls-112mm\"\u003e\u003cstrong\u003eLS 112mm\u003c\/strong\u003e\u003c\/a\u003e | \u003ca href=\"\/collections\/ls-120mm-throttle-bodies\"\u003e\u003cstrong\u003eLS 120mm\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eRunning a Gen V LT instead?
