Intake Manifolds

Don’t Waste Your Intercooler’s Efforts – Upgrade Your Intake Manifold!

Almost everyone knows it’s important and easy to get rid of your cheap factory air filter and replace it with a performance cold air intake system. Now that you’ve got all that new cooler air, what are you going to do with it? Those “in-the-know” diesel owners that want to get real performance will tell you that the secret to getting really effective airflow all the way into the engine is to remove the restrictive stock air intake manifold and replace it with a high performance diesel intake manifold.

So how much difference could replacing one silly looking little tube really make, you ask? Well, the engineers at AFE tested their Bladerunner Intake Manifold on a common rail 5.9L Dodge Cummins to find out. The results? The AFE Bladerunner intake manifold outflowed the factory intake by over 30%. Dyno testing was even more impressive, with the Bladerunner yielding an additional 17 horsepower and a massive 50 foot pounds of torque over stock.

How do these diesel intake manifolds make such a big difference? Let’s look at another impressive intake manifold from Gale Banks Engineering. Their new Monster Ram intake provides an inside diameter that is over 3 inches wide on the engine side of the manifold. The stock common rail Dodge intake manifold is crimped down to about 1 inch at the same point. The difference in flow and boost psi is enormous, and real life gains are felt immediately after installation. Want to really ram the air down your engine’s throat? Add an optional intercooler boost tube from Banks and add even more diesel performance.

Ford Powerstroke diesel intake manifolds like those from top manufacturers like CFM+ will give your truck better economy, more power, lower exhaust gas temperatures, and faster turbo spool up! For those that want an intake manifold made from a space-age composite material, CFM+ has just what you’re looking for. CFM+ composite material transfers diesel engine heat at a rate that is 900 times less than standard cast aluminum. That means your intercooler cooled air stays cool as it passes through and into your engine. More power is on the way, right away!

Performance diesel intake manifolds come with one additional feature that can come in quite handy if you’re really into performance. Most diesel intake manifolds come with pre-drilled and pre-tapped ports than come in awfully handy if you’re planning to install a water-methanol injection kit, a propane injection system, nitrous injection, or sensors to monitor pressure or temperature. The Banks Monster-Ram comes with six ports so you can install multiple items. AFE’s Bladerunner intake manifold comes with five ports, and the CFM+ intake manifolds come with or without pre-drilled ports; the choice is yours.
