Banks massive 3.5" boost tubes are the largest on the market, flowing 26-45% 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 inches. Every other competitive product on the market tops out at just 3.0 inches, and your factory pipes are only 2.5 inches 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. The Boost Tubes work with the stock Duramax intake components by using proprietary high-strength 5-ply silicone hoses. Unique to the 2020+ model, a pair of billet aluminum cold-side adapters are also used for the intercooler connection and the throttle body. These are specially made for the airflow requirements of the L5P and feature a Venturi-like taper on their inside diameter to maintain boost pressure and volumetric flow.Key Features: Huge increase in size and flow over stock and competitors (3.5" vs 2.5").Hot Side flows 490 CFM @ 12" vs stock 388 CFM. Cold Side flows 635 CFM @ 12" vs stock 435 CFM. Constant 3.5in diameter tubing for the best flow. Billet venturi couplers maintain boost pressure. Mandrel-bent aluminized steel construction. Allow the turbocharger to spool up faster. Spring-loaded constant tension clamps. Improves airflow by over 26% and 45%. 5-ply heavy-duty Nomex woven silicone couplers.

Would definitely recommend this watch.
Color: Black/Black/ Wjite Digital
Nice manly watch. Many Timex watches are too small. I love the size of this one and yet it's still lightweight. The face of the watch is neatly organized and very clear to read. Indiglo light works well at night. Only thing I see missing from this watch is a countdown timer. It has a stopwatch.

Big face, easy to read Timex quality at superior price
Color: Black/Black/ Wjite Digital
Great watch at amazing price. Better looking and much cheaper than current timex ironman models. Large face and numbers = easy to read. Has alarm and stopwatch functionality. Intuitive interface.

THIS WATCH IS NOT WATERPROOF AT 8 FT
Color: Black/Black/ Black Digital
DO NOT BUY TIMEX WATCHES - TIMEX ARE LIARS- I just called Timex and was told "a 30 meter rating is only for washing hands, not for swimming" This is a BIG FAT LIE. If the watch is only for swimming then SAY THAT!
I AM VERY DISATISFIED- THIS WATCH LEAKED IN 8 FT OF WATER WHILE SWIMMING IN MY POOL .
-ALSO, WATCH FACE IS VERY DARK AND HARD TO READ. Even if it didn't leak I would be very unhappy.
I want a refund? This watch is only a week old when it failed.
DO NOT BUY TIMEX WATCHES
