BD Diesel 2004.5-2006 Chevy Duramax LLY Stock Performance Plus Injector (0986435504)

BD Diesel is known for building robust performance parts for trucks, and their Stock Performance Plus injectors are a solid choice for your 2004.5-2006 Duramax LLY. If you're looking to get a little more out of your engine without going too extreme, these injectors are designed to give you that extra boost.

These aren't just off-the-shelf replacements; BD Diesel assembles them using OE procedures and calibrates them to strict tolerances. Each injector is tested on a Bosch 815 test bench across more than eight operating conditions to ensure they perform as expected. They come with new Bosch nozzles and control valves, and are flow-matched to within +/-2% of the OEM spec, which is tighter than the factory's +/-5% tolerance. This attention to detail means you can expect an improved power output of 5 to 15 horsepower, making them great for street driving, towing, and general performance use.

When you're replacing injectors, it's important to have parts that are built to last and perform consistently. These BD Diesel injectors are a well-built option that offers a noticeable increase in power while maintaining OE quality standards.
