The Banks Power 04-05 Chevy 6.6L LLY Techni-Cooler System is a high-performance intercooler designed to optimize boosted air density for increased continuous power and reduced exhaust gas temperatures. Constructed with a 25% larger core area and 34% more volume, it features restriction-free, mandrel-bent 3-inch boost tubes and durable cast end tanks that efficiently pack cool, dense air into the engine cylinders. This intercooler improves airflow, lowers boost air temps, and enhances oxygen content, resulting in higher power output, better fuel economy, and more consistent performance under demanding conditions. Its design emphasizes superior flow, durability, and thermal management, making it a top-tier upgrade for diesel performance enthusiasts.

Designed for 2004-2005 Chevy Silverado and Sierra models equipped with the 6.6L LLY engine, this system is a direct bolt-on replacement that accommodates stock mounting points. It is ideal for street driving, towing, and daily use where reliable, high-efficiency cooling is essential. The kit includes the intercooler core, cast end tanks, and mandrel-bent boost tubes, providing a straightforward installation. Compatible with stock components, it enhances overall engine performance by reducing EGTs and increasing airflow, making it suitable for those seeking improved power, durability, and fuel economy in their diesel trucks.

Overview

Optimizes the boosted air density for higher continuous power and lower exhaust gas temps. Restriction-free for superior flow with 25% larger core area and 34% more volume. Big boost tubes & durable cast end tanks pack cool, dense air into cylinders. Cooler EGTs, more MPG & constant-duty power. It doesn't get any cooler than Techni-Cooler Move over, pipsqueak. The stock intercooler has an inferiority complex. No wonder it's smaller than Techni-Cooler in every aspect: boost tubes. core area, inlet/outlet, even the end tanks. Most competitors use poorly designed sheet metal end tanks and provide inadequate flow volume. Banks cranks up the volume. Banks improves airflow into and out of the intercooler with big mandrel-bent 3 inch boost tubes. Large, rugged, high-efficiency cast end tanks that won't rupture under high-boost conditions. A huge inlet and outlet. And a 25% larger core area with a whopping 34% improvement in volume The king of cool. Removing restrictions and improving airflow lowers boost air temps. This increases the density and oxygen content of air entering the engine, which amplifies power, lowers exhaust gas temps (EGTs) and improves fuel economy. When EGTs are tamed, the tuner doesn't need to limit fuel delivery. So you get higher continuous, useable power and more power at any EGT. Very cool! Everything about Banks Intercooler is bigger, it doesn't get any cooler than Banks Intercooler. Key Features: Optimizes air pressure and distribution going into the intake manifold. High-efficiency custom-machined durable cast end tanks. Raises boost without increasing turbine drive pressure. Cooler EGTs, more MPG & constant-duty power. Improves flow of oxygen-rich air into cylinders 25% thicker core with 34% more volume. Improves Power, Durability & Fuel Economy. Packs cool, dense air into the cylinders. Accommodates stock mounting points. Lower restriction for superior flow. 3 inch mandrel-bent boost tubes. 2-year Warranty
