The Story
Description
Industrial Injection Dragon Fly 15% over injector nozzle for 2001-2004 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 6.6L LB7 Duramax. A drop-in nozzle upgrade — OE-supplier nozzles run through IIS's extrude-hone process to balance and match each nozzle, then individually tested on a state-of-the-art test stand for consistent atomization across the set.
Sold individually so you can swap one at a time or build a matched 8-pack. Comes with a new copper crush washer for installation. The 15% over rate gives a measurable bump in fuel economy and atomization vs. worn factory nozzles without requiring a tune or fuel-system upgrade.

- Dragon Fly 15% Over LB7 Nozzle
- Built with Brand-New OE Spec-Plus Parts
- Extrude-Honed for Balance Across the Set
- Individually Tested on Bench Stand
- Better Atomization, Improved Fuel Economy
- Direct Replacement
- Includes New Copper Crush Washer
- 1-Year Unlimited Mileage Warranty
- Part Number: 0433175275DFLY
Notes
