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.

How To Tune Intakes For More Horsepower Intake manifold tuning is critical for ensuring optimum horsepower across a wide rev range. Longer, narrower intake runners lend themselves well to low RPM ...

While variable geometry engine air intakes were banned from Formula 1 in 2006, only to become legal again later on, you can find this technology in many road cars today. Typically, it goes by the term ...

Variable-length intake runners aren't a particularly new concept, but Ferrari's system in its LaFerrari is next-level fascinating. Let Engineering Explained give you the rundown. You see variable ...

Engineers put a lot of hours into making the 2014 Chevrolet Cruze Clean Turbo Diesel a segment leader in EPA-estimated highway mileage. And one of the tricks they used to get there was something ...

Internal combustion engines are fairly simply machines. When you break it down, they are nothing more than air pumps. When it comes to making horsepower and torque, the simple fact is the more air you ...

When introduced for the '05 model year, the C6 received the evolutionary Gen IV LS2 powerplant, which carried ratings of 400 horsepower and 400 lb-ft of torque. While the new engine's cylinder heads ...

Since the days of relieving flathead Fords, we've known about the advantage of porting. Grind those critical passages with the right touch, and airflow through the engine improves-and with more air ...

Modifying your intake can fundamentally change how your engine breathes. Discover exactly how porting affects performance and if it's worth the effort.

The penetration of polymer-based components in automotive engines tends to be evolutionary. After extensive testing and development, a plastic or composite component is introduced on a single model, ...
