What is an air intake? Every vehicle is equipped with an air intake. There is a world of a difference between an aftermarket and OEM intake. Aftermarket intakes replaces the OEM intake by a metal pipe with an air filter at the end. This creates a performance boost due to its increased air volume intake. Many speculate the amount of performance benefits that it provides, but depending on how much the OEM intake restricted air flow the aftermarket will provide performance enhancement accordingly. There is a debate between cold air and short ram intakes. Many prefer cold air intakes due to its higher increase in performance, but this risks the chance of hydro-locking. Hydro-locking is when the air intake inducts water instead of air causing the vehicle to shut down, but in horrid cases permanently destroying the engine. Short ram intakes on the other hand does not risk the chance of destroying the engine because the intake is within the engine bay. Many debate the performance benefits for each, but there is no conclusive data as to which is better. |
