Techni-Cooler® Intercooler System

The Banks engineers carefully examined the stock Duramax intercooler, and then upgraded everything for superior results:

  • Stock has one plastic end tank; Techni-Cooler provides two durable, all-aluminum end tanks, which will never melt or burst under high-boost conditions
  • Large, streamlined end tanks optimize airflow and air density
  • With a thicker core than stock, Banks Techni-Cooler sports a 25% increase in volume. Very cool!
  • Techni-Cooler improves cooling for higher continuous power and lower exhaust gas temps
  • Banks' denser air charge improves the combustion process, resulting in greater engine efficiency and better fuel economy

click for storyDoes this sound familiar? "KROQ (106.7 FM) is the most powerful rock station in the world. It is also the number-one-rated radio station in Los Angeles. Radio programmers nationwide have endlessly copied KROQ's formats." Sounds a lot like Banks Power ... powerful, often copied ... so what better partnership could there be than KROQ and Banks Power teaming up to create the insane "Roq Rig." It's got just about everything we make for the Duramax, so if you've got one and you're looking to take it to the next level (of power and awesomeness) take a sec and check out what all went into making this dream truck a reality...

For those of you own on of those OBS (old-body-style) Ford F-250 Power Stroke diesels, you may or may not know that when you are towing, your EGT (exhaust gas temperature) tends to spike a little more than you'd like. One of the biggest reasons for that is because these trucks were not equipped with an intercooler. In today's world of diesel-powered vehicles, it is not uncommon to see a truck equipped with an intercooler from the factory.

When Chevy, Dodge, and Ford started offering turbocharged diesels, they were fine. And the manufacturers did not need to do anything extra to help cool the motors. But in this day and age, turbodiesel trucks are not only your standard work truck, but they are also built for performance! For the next couple months, you are going to follow along with us to see how you can make your very own OBS F-250 diesel a towing machine with performance parts from Banks Power. In this segment, you will see how Bill Cohron at Power Hungry Performance in Winder, Georgia, installs a Banks Techni-Cooler on our ‘96 Ford F-250.

PHP shows you how this kit is a complete bolt-on kit, with no welding and very little in the way of modifications. It only took Bill three hours for the install using basic tools. If you won one of these trucks and you tow a lot or plan on installing some performance stuff, make sure to check out for your performance needs. And if you're near Winder, Georgia, hit up Bill Cohron at:

Once the install was complete and a few test runs had been conducted, there was a 100 to 150 degree drop in EGT. This is especially good to know if you tow a lot of heavy equipment and/or run Stage 1 or larger injectors. Knowing the truck is running cooler always makes it a little less stressful going on those long trips.
