If you want to understand how engines work, it's important to realize the part the intake manifold plays in the grand power scheme. The basic job of the intake manifold is to route fuel and air in ...

In a naturally aspirated engine, as air comes in through the intake and passes through the throttle body, you've traditionally had two setups for what happens next. Using longer, narrower intake ...

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, ...

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.

Mustang enthusiasts have had a great deal to be thankful for in recent years. Ford has focused its resources on building the greatest Mustang in the Pony’s nearly 47-year existence, and we, the ...

No one around the shop could remember the last time we ran our 302 dyno mule, but it must have been five years ago. Fitted with a fresh set of AFR cylinder heads, the little beast started right up and ...

The air/fuel mixture entering the engine reaches the inlet valve at the pressure in the inlet manifold (the Manifold Pressure). Unless the throttle is wide open, this pressure will be less than ...

VW and its partners on the air intake manifold project, which was first discussed in 2009 at a conference in Germany (see our initial report here) and now has placed PP manifolds on a wide variety of ...
