Banks massive 3.5 inch boost tubes are the largest charge air cooler pipes on the market, flowing 680 CFM and 87 percent more air than stock! Smooth mandrel-bent tubes deliver more air to your engine while reducing boost pressure loss resulting in quicker turbo spool and more power.

Banks Boost Tubes are the largest charge air cooler pipes in the industry measuring in at a full 3.5 inch. Every other competitive product on the market tops out at 3.0 inch, and your factory pipes are only 2.5 inch with crushed bent corners and flimsy plastic components. By contrast, Banks Boost Tubes are made of high-quality aluminized steel for maximum strength and durability. With Banks Boost Tubes' smooth bends, your turbo can spool quicker thanks to improved boost pressure retention for maximum horsepower.

Key Features

  • Huge increase in size and flow over stock and competitors (3.5 inch vs 2.5 inch)
  • Billet venturi couplers maintain boost pressure
  • Mandrel-bent aluminized steel construction
  • Constant diameter tubing for the best flow
  • Allow the turbocharger to spool up faster
  • Spring-loaded constant tension clamps
  • Improves airflow by 87 percent over stock
  • Flows 680 CFM vs 364 CFM stock
  • 5-ply heavy-duty silicone couplers
  • Greater cooling capacity

Not what I’d hoped
Color: Multicolor a (5-pack), Size: Small
The fabric is nice, soft without being overly bulky. The design was almost what I wanted. I’ve been trying to find underwear that won’t ride up and is comfortable to wear under leggings. The fabric has a LOT of stretch around the legs and deforms quickly. Then it rides up and wrinkles. Smaller leg openings might make the difference.

Great & Comfortable
Color: Multicolor B (5-pack), Size: X-Large, Color: Multicolor B (5-pack), Size: X-Large
I have bought 2 packs of this underwear. I love wearing them. They are very comfortable, and the size fits perfectly. I like most of the colors. The Bamboo Cool lettering on the front does come off after washing though. Otherwise the underwear has been great to wear.

Better than woxer imo
Color: Multicolor B (5-pack), Size: Large
I've been buying Woxers, but theyre super expensive for what youre getting. These are similar in feel and style so i switched over. Another nice thing is i dont have to deal with wedgies like i do with the woxers. Theyre not perfect for wearing when its hot, youre still gunna sweat and these dont wick away sweat super well. But i havent seen many brands that do, and these are not the worst. Im 5'7" and 145lbs and these are comfy and tight enough but not snug. They still leave a bit of indentation on the love handles. You CAN tell that youre wearing them under pant if they are tight.
