Banks Power 04-05 Chevy 6.6L LLY Techni-Cooler System - 25978

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. More Safe Power. It's all bigger: 3.5" mandrel-bent boost tubes, aluminum end tanks, wide-open inlet and outlet with 31% bigger cross-sections and 12% thicker core area. Much greater flow volume. Increases air density for higher continuous power.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-CoolerMove 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 volumeThe 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!

Fidanza Performance is excited to offer the go to name in Diesel- Banks Power!

About Banks Power-

More than sixty years of engineering milestones for Banks Power president and founder Gale Banks began at age 14 with an engine teardown of his mother’s ’31 Ford Model A that resulted in an increase of 65 horsepower. Just two years later, in 1958, Gale was officially in the engine business, first in Lynwood, California, then in San Gabriel. He remains the hands-on president to the manufacturing and engineering complex that today occupies 12 acres in the San Gabriel Valley town of Azusa.

Banks Power is known far and wide as the premier designer and manufacturer of power-enhancing products for diesel- and gas-powered light trucks, motorhomes, and sport-utility vehicles. Since the 1960s, Gale’s futuristic high-performance engines have broken new ground while shattering world records. Banks Power is still the only company to have set records at Bonneville in both automobile and truck classes. Banks’ marine engines propelled racing boats to national and world championships.

In his quest for greater engine performance and endurance, Gale continued his racing endeavors, setting his first speed record, 189 mph in 1960 at El Mirage dry lake, with a modified 1953 Studebaker. Since then, Gale has been in the winner’s circle countless times, setting a litany of marine and automotive performance marks and laying claim to such titles as World’s Fastest Passenger Car, World’s Fastest Pickup, World’s Fastest Motorhome, and, most recently, World’s Fastest Diesel Drag Racing Truck.

The bedrock integrity of Gale Banks is at the very core of Banks Power. Gale’s fundamental principles combine old-fashioned business ethics and service with leading technology, elegantly engineered products, superior construction, scientifically proven performance, and competitive prices.

In military mode, Banks engines were chosen to power U.S. Navy SEAL covert-action boats. Banks Technologies, a Gale Banks Engineering division, was awarded the contract to supply Oshkosh Defense with its V8 diesel 866T engine to power all Joint Light Tactical Vehicles.

As a recognized authority, Gale has taught engine design to graduate students at General Motors Institute, covering many subjects: engine architecture, turbochargers (design and application), fuel systems, exhaust systems, marine turbocharging, ignitions and camshafts, intercooling, and more.

The Banks company history is studded with technological achievements, including Gale’s pioneering work in turbocharging marine engines in 1969; the premiere of twin-turbo small-block Chevy engines in 1978; the invention (and patent) of the Banks OttoMind electronic fuel-management module in 1997; transmission control systems, exhaust scavenging systems, and the recent invention (and patent) of the iDash DataMonster, the only instrument to calculate, log and display an exclusive suite of engine parameters including Manifold Air Density.

Banks prides itself on being a company of engineers who see the future, pin the accelerator pedal, and aim right toward it.

Fidanza Performance, founded in 1997, is a leading US manufacturer of high-quality lightweight aluminum flywheels, precision adjustable cam gears, and high-performance clutches. With nearly 20 years in the automotive performance market, Fidanza is renowned for its expertise and respected globally, offering products for a wide range of vehicles, from European sports cars to modern muscle cars and imports. The company originated in racing, with founder Lou Fidanza's success in the SCCA leading to the creation of specialty parts like aluminum flywheels. Fidanza has since expanded its product line to include cam gears and performance clutches, gaining a loyal customer base and worldwide recognition. In 2023 Fidanza opened the SpeedParts4Less Marketplace which sells other manufacturers quality high performance parts!
