Push More Power Without Letting Heat Slow You Down

If your Duramax is running harder than ever, but your factory intercooler just can’t keep up, the aFe BladeRunner GT Series Intercooler is the upgrade you’ve been looking for. Built for 2011–2016 Silverado and Sierra HD trucks, this intercooler is designed to handle serious performance without sacrificing reliability. It outflows the factory tube-and-fin design by 36 percent, which means cooler, denser air entering your engine and noticeably lower EGTs. The bar-and-plate core is paired with tough TIG-welded end tanks and billet aluminum inlets and outlets for long-lasting strength in high boost conditions. You also get four built-in 1/8-inch NPT ports, making it easy to hook up sensors, gauges, or nitrous kits if your build demands it. Whether you’re towing, racing, or just pushing more power through your LML, this intercooler is built to keep up. It delivers dependable cooling under pressure and looks just as tough as it performs. If you're ready to unlock real performance gains, this is the place to start.

Designed To Flow More Air And Handle More Boost

The aFe 46-20111 BladeRunner GT Series Intercooler is a high-performance replacement engineered specifically for 2011–2016 GM 6.6L Duramax LML trucks. Its 2.5-inch bar-and-plate core is a significant step up from the stock tube-and-fin layout, delivering increased surface area for heat dissipation and improved internal flow characteristics. This intercooler incorporates aFe’s Multi-Directional Vane technology inside the end tanks to evenly distribute airflow across the core, helping to reduce hot spots and maximize cooling efficiency. The end tanks themselves are made from 3/16-inch TIG-welded aluminum, built to withstand the stress of elevated boost pressures and extreme use. Rated at 200 PSI, it’s more than capable of supporting high-horsepower or race-tuned builds. The addition of billet aluminum inlet and outlet connections provides a tight, leak-free fit and compatibility with the stock boost tubes. Four auxiliary ports give you added flexibility for aftermarket sensors or performance accessories. This intercooler is a reliable, track-tested upgrade designed for diesel owners who demand more than what factory parts can deliver.
