OBJECTIVE: Wet flow, pressure excursions, port volume, runner length, plenum volume—all these figure into an engine's overall efficiency. But there's more… Sometimes theory is neat, but sometimes it ...

The intake manifold distributes air or air/fuel mixtures to the individual cylinders under varying engine speeds, loads, and environmental conditions. Whether the working flow is pure air, air/fuel, ...

What’s the first thing you look at when checking out someone’s engine bay? Chances are the intake manifold is at the top of that list. The type of intake manifold can tell a lot about it; stock ...

Form and Function - A Look at Intake Manifold Design: Intake manifolds play a huge part of power production, here’s some of the hows and whys Internal combustion engines are fairly simply machines.

Intake manifolds may not be the most well-known automotive components, but that doesn't take away from their importance. These devices are responsible for sending a precise mixture of fuel and air to ...

Your intake manifold. It takes in air and sends it to your engine's combustion chamber. This is basically the start of the combustion process. After all, you can't have combustion without air.

If you think about it, there are things about your car that just don’t make sense. You’ve been told that more air is a good thing for power, that a cold air intake, more scoops, more vents, etc, are a ...

Popping the hood of a new Mercedes-Benz 300SL Gullwing must have been quite an experience for most enthusiasts in the Fifties. For starters, the 3.0-liter straight-six sat canted at a fifty degree ...

With intake manifolds made of polypropylene (PP), Röchling Automotive (Mannheim, Germany) says it has set new benchmarks in terms of cost, weight, and acoustics. These three criteria have been ...
