The more air and the cooler and denser the air charge that ends up entering your engine, the better your overall diesel performance will be. And every link in the air intake and delivery chain that you can strengthen, the better. Upgrading your OEM filter with a cold air intake system is a great start, and you’ll definitely see performance gains. Upgrade the intercooler and you’re really starting to make cool power. Finish off the system with a performance diesel intake manifold and you’re doing all you can to maximize gains and cooling. Or are you?

Just like the old adage that a team is only as strong as its weakest teammate, you need to make sure every member of your air intake and cooling team is giving its very best. Try adding a Ram Air Scoop to force a charge of cool, pressurized air into the filter housing for optimal intake efficiency and more power. Taking air in from outside the engine compartment ensures you’re getting the coolest air possible, and the result is improved fuel economy, reduced smoke and lowered exhaust gas temperatures.
