Air Intake Guide

Are you looking for a cold air intake but aren't sure which one to buy? Majestic Modifications would like to help you make your decision.

Cold Air Intakes add horsepower by increasing the air available for the engine, and improving the air that the engine receives. We have posted earlier how air intakes work, so how do you know you are getting the best one, and what is the difference in the different brands and designs?There are severaly things to consider when looking at an air intake. The best thing to do it to look at the dyno proven results. These (typically) are an accurate representation on how it will perform on your vehicle. We have to assume that the only change from the first run to the second is the air intake, and that other "cheater" additions have not been made, such as a performance chip, etc. Assuming the dyno results are accurate, these are a good point for comparison.

Many have fallen victin to believing that bigger is better when considering and air intake system. this is true in some cases, but not in others. Consider the straw analogy. As the straw diameter increases from zero diameter, the amount of air/fluid allowed through the straw will increase, but only up to a certain point. There is a point where the straw diameter increase will negatively affect the amount that can be passed through the straw because the force pulling it through has not increase (this would be equal to the cylinder displacement remaining constant.) On todays smaller import engines, sometimes the dyno prooves that a 2.5 or 2.75 inch diameter intake can outperform the larger 3 inch diameter intake. This is of course a product of the tubing length and diameter, as well as the breathability of the actual filter.

If that didn't make sense, don't worry. Trust the dyno results. Some intakes claim huge maximum power gains, but these "maximum" horsepower gains should be treated like the max output of an amplifier... you might see the maximum gain only under ideal conditions (such as accelerating downhill into the wind at 6500rpms, or in the example of the amplifier, it is struck by lightning.) The real output gains are somewhere near the middle to bottom half of the actual range for most tuners and drivers.
