The larger opening supports compatible naturally aspirated, turbocharged, and supercharged induction systems without making unsupported horsepower claims. - Complete Drive-By-Wire Assembly: The throttle body arrives completely assembled with its electronic stepper motor and operating electronics already installed. Installation does not require disassembling the original throttle body to transfer its internal electronic components. - Six-Pin Gen V Connector: The integrated six-pin electrical connector is designed for compatible late-model Gen V wiring harnesses and electronic throttle-control systems. This connector configuration helps distinguish the SD103LTXB from electronic throttle bodies manufactured for earlier Gen III and Gen IV LS applications. - CNC-Machined Black Billet Housing: Nick Williams precision-machines the throttle-body housing from billet aluminum for accurate component fit and throttle-blade operation. The black anodized finish provides a clean appearance for exposed performance intake and engine-bay installations. - Confirmed Fitment And Installation Requirements: Fits compatible 2014-and-newer Gen V Corvette and truck applications and 2016-and-newer Gen V Camaro applications using 5.3L or 6.2L LT1, LT4, L83, L86, or L8B engines. A compatible aftermarket intake manifold with a 103mm opening and application-specific tuning are required; mounting bolts are included. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CQRX83SZ | | Best Sellers Rank | #1,893,445 in Automotive ( See Top 100 in Automotive ) #2,360 in Automotive Replacement Fuel Throttle Bodies #17,507 in Automotive Replacement Fuel Injection Products | | Brand | Michigan Motorsports | | Date First Available | December 21, 2023 | | Exterior | Natural | | Item model number | SD103LTXB | | Manufacturer | Nick Williams | | Manufacturer Part Number | SD103LTXB | | Model | Throttle Body | ## Images ![Nick Williams SD103LTXB 103mm Black Billet Drive-by-Wire Throttle Body | Fits 2014+ Gen V LT V8 5.3L 6.2L LT1 LT4 L83 L86 L8B | CNC-Machined with Electronics, 6-Pin Connector & Mounting Bolts Included - Image 1](https://m.media-amazon.com/images/I/71flg8XzIrL.jpg) ![Nick Williams SD103LTXB 103mm Black Billet Drive-by-Wire Throttle Body | Fits 2014+ Gen V LT V8 5.3L 6.2L LT1 LT4 L83 L86 L8B | CNC-Machined with Electronics, 6-Pin Connector & Mounting Bolts Included - Image 2](https://m.media-amazon.com/images/I/71F6fotAP6L.jpg) ![Nick Williams SD103LTXB 103mm Black Billet Drive-by-Wire Throttle Body | Fits 2014+ Gen V LT V8 5.3L 6.2L LT1 LT4 L83 L86 L8B | CNC-Machined with Electronics, 6-Pin Connector & Mounting Bolts Included - Image 3](https://m.media-amazon.com/images/I/71J95V3tkwL.jpg) ![Nick Williams SD103LTXB 103mm Black Billet Drive-by-Wire Throttle Body | Fits 2014+ Gen V LT V8 5.3L 6.2L LT1 LT4 L83 L86 L8B | CNC-Machined with Electronics, 6-Pin Connector & Mounting Bolts Included - Image 4](https://m.media-amazon.com/images/I/71AH7ff7ZiL.jpg) ![Nick Williams SD103LTXB 103mm Black Billet Drive-by-Wire Throttle Body | Fits 2014+ Gen V LT V8 5.3L 6.2L LT1 LT4 L83 L86 L8B | CNC-Machined with Electronics, 6-Pin Connector & Mounting Bolts Included - Image 5](https://m.media-amazon.com/images/I/71myvTWD3sL.jpg) ## Frequently Bought Together - Nick Williams 103MM Black 2014+ Gen 5 LT DBW Throttle Body, SD103LTXB CNC Billet Electronic Drive by Wire -Fits 5.3 6.2 LT1 LT4 L83 L86 L8B - GM Parts 12677004 Intermediate Fuel Feed Pipe - L83 5.3 and L86 6.2 Gen 5 Engine Vacuum Pump Plugs 11546665/11602943 Qty 2 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/632222779-nick-williams-sd103ltxb-103mm-black-billet-drive-by-wire-throttle](https://www.desertcart.hr/products/632222779-nick-williams-sd103ltxb-103mm-black-billet-drive-by-wire-throttle) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-08*
