This throttle body ships with an integrated throttle position sensor and idle air control valve, making it a complete bolt-on assembly for naturally aspirated and forced induction setups. It suits engine builders, swap installers, and performance tuners working with LS-platform vehicles.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e102mm bore diameter supports higher airflow than factory LS throttle bodies\u003c\/li\u003e\n\u003cli\u003eAluminum construction resists heat soak and holds up under boost\u003c\/li\u003e\n\u003cli\u003e4-bolt mounting flange matches standard LS intake manifold patterns\u003c\/li\u003e\n\u003cli\u003eIncludes throttle position sensor for plug-in signal compatibility\u003c\/li\u003e\n\u003cli\u003eIncludes idle air control valve for stable idle tuning\u003c\/li\u003e\n\u003cli\u003eCompatible with LS1, LS2, LS6, LS7, and LSX engine families\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor GM Gen III LS1 equipped vehicles\u003c\/li\u003e\n\u003cli\u003efor GM Gen III LS2 equipped vehicles\u003c\/li\u003e\n\u003cli\u003efor GM Gen III LS6 equipped vehicles\u003c\/li\u003e\n\u003cli\u003efor GM Gen III LS7 equipped vehicles\u003c\/li\u003e\n\u003cli\u003efor GM Gen III LSX equipped vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNaturally aspirated LS builds chasing top-end airflow\u003c\/li\u003e\n\u003cli\u003eTurbocharged and supercharged LS setups needing a larger throttle inlet\u003c\/li\u003e\n\u003cli\u003eEngine swap projects using LS-platform drivetrains\u003c\/li\u003e\n\u003cli\u003eIntake manifold and cylinder head upgrade combinations\u003c\/li\u003e\n\u003cli\u003eStreet and strip builds requiring reliable idle control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThrottle Body Bore\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e102mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting Style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4-bolt flange\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIncluded Sensors\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTPS and IAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine Family\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGM Gen III LS1, LS2, LS6, LS7, LSX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Does this throttle body include the TPS and IAC? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, both the throttle position sensor and idle air control valve are included as part of this assembly, so no separate sensor purchase is needed for a standard install.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Will a 102mm throttle body require tuning after installation? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, moving to a larger bore changes airflow at idle and part throttle, so a recalibration or tune is typically needed to keep idle quality and throttle response correct.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSlight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"Solid Spare","offers":[{"title":"Default Title","offer_id":50557180117078,"sku":"ZZ3P02089","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/8460\/0662\/files\/s-l1600_1ba2351a-92b2-41e5-95f8-f94da7f8086c.jpg?v=1790977664","url":"https:\/\/www.solidspare.com\/products\/aluminum-102mm-4-bolt-throttle-body-tps-iac-for-gm-gen-iii-ls1-ls2-ls6-ls7-lsx","provider":"Solid Spare","version":"1.0","type":"link"}
