Improves airflow from the intercooler. Delivers up to a 64 percent reduction in pressure loss. Result: greater air density and a more responsive, fuel-efficient engine. Includes 3-1/2 in. mandrel-bent boost tube. An intercooler increases air density, allowing your engine to produce more power. You Dont want to restrict the flow of air exiting the intercooler, right? Unfortunately, thats exactly what the stock piece does. The factory inlet is cramped and angular compared to Banks larger, streamlined cast-metal High-Ram. Banks High-Ram intake flows air much more efficiently, providing greater boost without the drawback of raising turbine backpressure. In flow tests, the High-Ram intake delivers up to a 64 percent reduction in pressure loss. Improves acceleration and fuel economy! Includes a 3-1/2 in. constant-diameter boost tube to flow air from the intercooler without restriction. Ramming It To The Competition. Being an engineer as well as a competitive-as-hell hot-rodder means pursuing every airflow advantage possible. Back in 1998, my original Dodge High-Ram crushed the flow of the stock elbow. This established yet another path to enhanced diesel power and mileage. But it also invited a slew of imitators, offering knock-off, pretender versions. Because theyve essentially copied our original, the competitors numbers look pretty good. They say imitation is the sincerest form of flattery. Well, as much as I appreciate the compliment, its reality-check time for Banks competitors. At Banks, we settle for nothing less than the top of the market when it comes to performance. Size Matters. Our new 3-1/2 in. CNC High-Ram out-boosts the competitors by up to 56.9 percent. This leaves the competitors with a dilemma. Will they just copy Banks all over again? Probably. But for customers who appreciate quality, credentials, and true engineering, Banks is the only game in town. And weve got the records to prove it!
