The 103mm inlet is sized for high-horsepower boosted and naturally aspirated LS builds, and Texas Speed machines the bore for controlled airflow at lower rpm so part-throttle drivability and street manners are retained. It is not compatible with Gen III 24x engines.\u003c\/p\u003e\u003cp\u003eThe throttle body is designed in CAD and machined on a 5-axis CNC. Texas Speed offers swappable inlet flange adapters as optional add-ons: a standard 115mm OD mounting flange, a Vanjen flange or a V-band flange. Because of the larger 103mm blade, an aftermarket intake manifold is required; the throttle body is not a direct bolt-on to the OEM intake, and engine calibration is required after installation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Drive-by-wire (DBW) electric throttle body\u003c\/li\u003e\n\u003cli\u003eInlet\/bore size: 103mm\u003c\/li\u003e\n\u003cli\u003eMaterial: CNC-milled billet aluminum, 5-axis machined\u003c\/li\u003e\n\u003cli\u003eFinish: Silver, raw machined\u003c\/li\u003e\n\u003cli\u003eOptional flange adapters: Standard 115mm OD mounting flange, Vanjen flange or V-band flange (add-on at ordering)\u003c\/li\u003e\n\u003cli\u003eEngine compatibility: Gen IV LS engines with 58x reluctor wheels only; not compatible with Gen III 24x engines\u003c\/li\u003e\n\u003cli\u003eIntake manifold: Requires an aftermarket intake to accept the 103mm blade; not a direct bolt-on to the OEM intake\u003c\/li\u003e\n\u003cli\u003eTuning: Engine calibration required after installation\u003c\/li\u003e\n\u003cli\u003eIntended use: High-horsepower boosted and naturally aspirated LS builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKit Includes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTexas Speed 103mm drive-by-wire throttle body, silver raw machined (TSP-DBW103TB)\u003c\/li\u003e\n\u003cli\u003eFlange adapter: standard 115mm OD, Vanjen or V-band (optional add-on, selected at ordering)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOrdering Options\u003c\/h3\u003e\u003cp\u003eTexas Speed offers an optional Flange Type add-on for this throttle body: the TSP 103mm drive-by-wire throttle body adapter in standard 115mm OD mounting flange, Vanjen flange or V-band style.
