BD Diesel 2006-2007 Chevy Duramax LBZ Stock Performance Plus Injector (0986435521)

If you're working on a 2006 or 2007 Chevrolet Silverado or GMC Sierra equipped with the Duramax LBZ engine, these BD Diesel Stock Plus injectors are a solid option for replacement. They're built to OE quality standards, meaning they're assembled using the same procedures and calibrated on computerized equipment just like the original parts. This attention to detail ensures they'll operate perfectly in your truck.

What sets these apart from a basic OE replacement is the 'Plus' designation. Each injector is flow-matched to a tighter tolerance than stock, specifically within +/- 2% compared to the OEM's +/- 5%. This improved calibration, along with new Bosch nozzles and control valves, helps these injectors produce an extra 5 to 15 horsepower. They're tested on a Bosch 815 test bench across multiple operating conditions to verify their performance, making them suitable for street driving, towing, and general performance use.

BD Diesel has these injectors assembled by Bosch-trained technicians, ensuring a well-built part that's ready to go. They come as exchange sets, meaning you'll typically need to send your old injectors back, and they are sold individually, so you can replace exactly what you need or get a full set.
