What is the advantage of the 102mm throttle body over the 92mm version?\u003c\/h3\u003e\n\u003cp\u003eThe 102mm opening provides a larger airflow path, making it better suited to higher-horsepower LS combinations with upgraded cylinder heads, camshafts, intake manifolds, increased displacement, or other modifications that increase airflow demand. A 92mm throttle body may be a better fit when maximum airflow is not required.\u003c\/p\u003e\n\u003ch3\u003e2. Is a 102mm throttle body too large for my LS engine?\u003c\/h3\u003e\n\u003cp\u003eIt depends on the complete engine combination. Bigger is not automatically better. Intake manifold size, displacement, cylinder heads, camshaft, RPM range, and horsepower goals should justify the larger throttle opening.\u003c\/p\u003e\n\u003ch3\u003e3. Does the progressive throttle pulley help with a large 102mm throttle body?\u003c\/h3\u003e\n\u003cp\u003eYes. The progressive pulley provides more controlled initial throttle opening, helping improve low-speed modulation while still allowing full throttle when needed. This is especially useful in high-horsepower off-road builds where precise pedal control matters.\u003c\/p\u003e\n\u003ch3\u003e4. Does this throttle body include an IAC motor or TPS?\u003c\/h3\u003e\n\u003cp\u003eNo. It includes provisions for both components, but the Idle Air Control motor and Throttle Position Sensor are sold separately. The IAC uses (2) 8-32 UNC mounting screws and the TPS uses (2) M4 x 0.7 screws.\u003c\/p\u003e\n\u003ch3\u003e5. Will a 102mm throttle body automatically increase horsepower?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily. The larger bore removes a potential airflow restriction, but the engine must be capable of using the additional airflow. The greatest benefit is typically seen when the existing throttle body has become a restriction in the overall engine combination.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":56871448805542,"sku":"860005-1","price":279.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8394\/6406\/files\/860005-1-Holley-102mm-Sniper-EFI-Throttle-Body-1.jpg?v=1785166192"},{"product_id":"holley-efi-billet-fuel-rail-kit-gm-ls-truck-intake-black","title":"Holley EFI Billet Fuel Rail Kit for GM LS Truck Intake – Black","description":"\u003cp\u003eThe \u003cstrong\u003eHolley EFI Billet Fuel Rail Kit for LS Truck Intakes\u003c\/strong\u003e is a high-flow fuel delivery upgrade for GM LS engines that need more fuel capacity than a factory-style rail can provide.
