Editor's Note: As inanimate as intake manifolds may appear, they provide a path to both major and minor on-track power gains. Selection is one thing; "tuning" them to specific applications is a blend ...

Whether it's a puddle under your car or a grimy mess inside your engine bay, finding engine oil where it's not supposed to be is never an enjoyable experience. Normally, oil remains contained within ...

Carburettors versus electronic fuel injection (EFI); automotive fans above a certain age will be well versed in the differences. While early EFI systems had their failings, the technology brought with ...

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 ...

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 ...

With a little help from our friends at Tune Time Performance, we were able to find a willing TrailBlazer (owner Jim Skeenes) in which to test the new FAST (Fuel Air Spark Technology) truck intake ...

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.

Gasoline engines burn a mixture of fuel and air. In order to create horsepower, your engine must maintain a good quantity and velocity of air/fuel charge into the combustion chamber. Think of the ...
