Get ready to take your engine to the next level with Banks' massive 3.5-inch boost tubes! These pipes are the biggest and baddest in the game, flowing a whopping 680 CFM and 87% more air than stock. Thanks to their smooth mandrel bends, they'll deliver more air to your engine, resulting in quicker turbo spool and a power boost.
Most competitors only offer 3.0 inches, while our factory pipes are just 2.5 inches with squished ends and weak plastic parts. In comparison, Banks Boost Tubes are constructed from top quality aluminized steel for ultimate toughness and lasting power. Thanks to the seamless curves of Banks Boost Tubes, your turbo will spool up faster, resulting in maximum horsepower from improved boost pressure.
