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.

Welcome to the frequently asked question (FAQ) section!

Other questions may be answered upon request through an Email or phone conversation.

1.) What does an Intake do?
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.

2.) How much horsepower / torque will I gain?
Depending on the intake type, and application horsepower and torque gains will be generated accordingly. Whether cold air or ram air much of the gains are debated. Depending on how restrictive the OEM intake was, exact horsepower and torque gains are debatable.

3.) Does Intakes void warranty?
Intakes do not void warranty. A dealership cannot "void the warranty on the whole car" just because you have a CAI (Cold Air Intake) or aftermarket wheels. if they are trying to deny warranty service, they must prove that the mod caused the problem. Of course, adding a turbo kit (for example) can put a lot of stress on the engine itself, as well as to the drivetrain. Don't be surprised if the dealer refuses to perform warranty service on a heavily modified car, that's just common sense.

This is all part of the "Magnuson-Moss" Warranty Act, which protects consumers against dishonest business practices by:
"The Act makes it easier for purchasers to sue for breach of warranty by making breach of warranty a violation of federal law, and by allowing consumers to recover court costs and reasonable attorneys' fees."

(In short, if they try to void your warranty and your mod could not have caused the problem)

What is Hydro-Locking?
Hydro-Locking is when the intake inducts water rather than air. This process causes the engine to either shut off for a period of time, or permanently damaging the engine. This often happens with cold air intakes due to the location of the filter.

Does an intake increase gas mileage?
Yes, gas mileage will improve because the harder the engine works to suck in air through the OEM intake the car uses up more gas. With a less restrictive intake, and one with quicker response will save gas.
