About This Product
Optimizes the boosted air density for higher continuous power and lower exhaust gas temps. Lowers restrictions 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
Specifications
Less restriction. Flows great.
The stock intercooler is riddled with restrictions that cause turbulence, which kills airflow and power. Banks minimizes restrictions by making the flow area bigger throughout, from the 3 inch mandrel-bent boost tubes to the 25% thicker core, which has a whopping 34% increase in flow volume.
Airflow cranks in Banks’ end tanks!
Most competitors have poorly designed sheet metal end tanks with square corners that choke airflow. Techni-Cooler’s large, high-efficiency custom-machined end tanks have two advantages.
One: The streamlined design and rounded corners improve airflow.
Two: Banks’ cast end tanks will never melt or burst under high-boost conditions.
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. And when EGTs are tamed, the tuner doesn’t need to limit fuel delivery. So you get higher continuous, useable power and more safe power at any EGT. Very cool!

awsome upgrade
"fit perfectly, due to age (2005 engine)it didn;t have a parts breakdown in instructions. BUT it is on and dropped my EGT by over 100 degrees when just cruising around. LOVE IT!"
Great product but does not
"Great product but does not come with new band clamps for the hoses and new hose for the driver side lower"
Only minor modifications needed to

Lly intercooler
"Great product, fits great, works great. Super fast shipping."
Don't waste your money else where, by Banks!
"Before I added the banks inner cooler and sixgun tuner on my 2005 Silverado 2500 6.6 LLY I was running 4 inch magna flow exhaust,K&N cold air intake,AFE turbo inlet. It ran decent then but once I put the intercooler and the six gun tuner on it it turned into a rocket! Day and night improvement! Highly recommend it! I keep it on level three, seems to be best for me. I am a plumbing contractor and this is my daily driving truck. Thank you Gail Banks! Bruce R"
Quality and attention to detail.
"The 3 inch tubing on the driver side is in a way that gives you more clearance around the power steering lines. GM had a bad design on the LB7 Duramaxes that put the CAC tubing too close to the power steering lines, and then they "fixed" it by using a smaller diameter tube on the LLY Duramaxes. Banks took care of both problems you don't have to worry about the piping or power steering hose being rubbed through and have the most air flow possible. The charge air cooler itself is much thicker and the cores are wider as well. The air flow difference is huge, i had to recalibrate my vane position tables because too much boost was making its way on through to the engine on the top end. That also means the vanes are a tiny bit more open reducing my drive pressure. The third thing i liked about it was how it moved the radiator closer to the engine a half an inch. This may not seem like much but it also pushed the fan shroud closer to the engine, now the engine fan is tucked fully within the fan shroud and the allowing the engine fan to draw air more efficiently."
Top notch in performance.

The packaging was well done
"The packaging was well done my inner cooler arrive fairly quick. The boost tubes had a bunch of scratches in them didn’t bother me too much because they were where you couldn’t see them. The only downfall is I didn’t get any new clamps with my order. I will know soon enough if I’m getting better, gas, mileage."
Great fit and it works
"Great fit and it works wonderful. Banks stuff is always spot on."
Q&A
- I have a 2002 LB7 that I need to replace the intercooler tubes. I saw a replacement intercooler kit. I don’t want to replace the intercooler, do you offer just the tubes?
