These injectors give your LML Duramax the extra fuel it needs to support tuning and turbo upgrades while still keeping the truck enjoyable to drive every day. They start life as genuine OEM remanufactured injectors, which means fitment and reliability stay exactly where they should be. From towing harder to pulling stronger through the mid-range, the added fuel delivery shows up where you actually use it. Many owners choose this size because it opens the door to more power without pushing the limits too far. Installation is straightforward, with new o-rings and a copper crush washer included for peace of mind. If you are looking for a noticeable upgrade that still feels refined, this injector set makes a lot of sense.\u003c\/p\u003e\n\u003ch4\u003eOEM Reman Injectors Enhanced With Precision Flow Matching\u003c\/h4\u003e\n\u003cp\u003eThe Industrial 0986435409-R4 injectors are built on a factory OEM remanufactured foundation and then modified to deliver a controlled 50% increase in fuel flow. Industrial Injection uses extrude honing and careful balancing to ensure each injector flows consistently across all cylinders. That consistency plays a major role in maintaining smooth idle, stable combustion, and long-term engine health. Designed specifically for 2011-2016 Duramax LML applications, these injectors install as a direct replacement with no physical modifications required. They are well suited for trucks running tuning, upgraded turbochargers, or other airflow improvements that demand more fuel. Each injector is backed by a one-year unlimited mileage warranty, reinforcing their focus on reliability as well as performance. With proper tuning, this injector set delivers increased fuel volume while maintaining the precision expected from an OEM-based component.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e2011, 2012, 2013, 2014, 2015, 2016 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax LML\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt from genuine OEM remanufactured injectors\u003c\/li\u003e\n\u003cli\u003eModified and flow balanced by Industrial Injection\u003c\/li\u003e\n\u003cli\u003e50% over injectors designed for increased fuel flow\u003c\/li\u003e\n\u003cli\u003eBest suited for tuned or performance-modified trucks\u003c\/li\u003e\n\u003cli\u003eNot recommended for use with stock engine tuning\u003c\/li\u003e\n\u003cli\u003eIncludes new copper crush washer and o-rings\u003c\/li\u003e\n\u003cli\u003eDirect fit for 2011-2016 LML Duramax applications\u003c\/li\u003e\n\u003cli\u003eRequires custom tuning for proper performance\u003c\/li\u003e\n\u003cli\u003eBacked by a one year\/unlimited mileage warranty\u003c\/li\u003e\n\u003cli\u003e$150 core charge per injector refunded if returned within 30 days\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Industrial Injection","offers":[{"title":"Default Title","offer_id":68032354779409,"sku":"IIS-0986435409-R4","price":587.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/0986435409-RX_4bd0aeb3-b44d-416c-9f8e-ebbcf66a79b3.jpg?v=1794464741","url":"https:\/\/gautoparts.com\/products\/industrial-0986435409-r4-factory-oem-reman-50-over-injector-11-16-gm-6-6l-duramax-cab-chassis","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
