Why Choose Banks Boost Tubes Massive flow improvement: Up to 65% greater flow area vs stock tubing. Mandrel-bent aluminized steel: Durable, constant-diameter construction for optimal airflow. Quicker turbo spool & lower EGTs: Better flow and cooling capacity reduce exhaust gas temps and improve response. High-temp silicone couplers: 4- and 5-ply heavy-duty couplers with red powder-coat stop for secure grip. Reliable clamping: Spring-loaded constant-tension clamps prevent leaks and blown boots. Compatible: Works with stock elbow or Banks Monster-Ram (3.5" or 4"), and with stock or common aftermarket intercoolers with standard inlet/outlet locations. Built for performance and longevity, Banks Boost Tubes deliver measurable gains in power, response, and durability. Combine with a Banks Monster-Ram intake for maximum results.
