Cold air is denser than hot air, and denser air provides more oxygen for more complete fuel combustion. More oxygen = more combustion = more power and better efficiency for your engine. The Airaid MXP intake system applies this simple formula to ramp up your engine's horsepower and torque for awesome performance gains.


MXP Cold Air Intake System

Airaid Intake Installed

The MXP intake is Airaid's top-of-the-line system. The air box and the intake tube serve as aggressive, serious upgrades over your stock intake. The rotomolded, cross-linked, high-density polyethylene construction of the box and the tube is durable and helps keep air cooler because it is more heat resistant than aluminum or steel.


The air box with an aluminum cover isolates the air filter from engine heat on all sides, thus helping to ensure that the air that is pulled into the engine is cold and dense. The box is also designed to better route incoming air than your factory air box to more efficiently direct air through the filter. And the cover also keeps out debris, minimizes noise, and removes easily for air filter servicing.


The intake tube also generates more airflow to the engine. The tube's smooth, wide-open design delivers high-volume, high-velocity air into the throttle body. Not only does the tube allow air to flow along an unrestricted path, but it is also free of noise baffles that would hinder airflow.


SynthaFlow Oiled Air Filter

Airaid SynthaFlow Air Filter Layers

This Airaid intake kit includes a SynthaFlow oiled air filter that offers improved airflow and has a 99.6-percent filtration rate for superior protection. The large, 360-degree conical filter is composed of 4 layers of oiled cotton gauze that filter out contaminants while allowing clean air through. A fifth layer of synthetic material acts as a barrier to keep oil from leaking through and causing damage to any sensors on the intake tract. The cotton and synthetic materials are sandwiched between 2 layers of stainless steel mesh that provide rigid durability.


This Airaid SynthaFlow filter is washable and reusable. It is recommended that you clean and re-oil your SynthaFlow filter every 30,000 to 50,000 miles with an Airaid cleaning and oiling kit (sold separately).


Gains in Horsepower and Torque

Airaid dyno chart

When tested on a dynamometer, this intake system demonstrated maximum increases of 33 hp and 35 ft-lb of torque. The dyno test is an accurate way to test an air intake's ability to affect an engine's power curve, but factors such as engine condition and fuel type can cause results to vary.

Review from a similar Airaid MXP in Air Intakes


My 4Runner is a big vehicle and it takes a bit to get going, so anything that adds a bit of power and torque is welcomed. When I installed this intake it did seem to add just a bit more get up and go to my acceleration. The thing I liked best about the intake is that when accelerating it sounds better, a bit deeper sound than before. When idling or normal driving there was not a noticeable difference in sound. My gas mileage after 1,000 miles of use was just a bit improved. There was not enough improvement that I would conclusively say it improves mileage but it probably will not hurt your MPG. 102573
