## Overview

The K&N Cold Air Intake System (model AIR-515-302) is a vehicle-specific upgrade for 2010-2021 Toyota 4Runner and FJ Cruiser models, delivering up to 15% horsepower gains through a roto-molded air box and oil-free synthetic filter. Designed for easy bolt-on installation without recalibration, it features washable, reusable filter media and precision-engineered airflow components to enhance engine performance and sound.

## Description

The AIRAID MXP Air Intake System represents the ultimate in AIRAID’s cold air induction systems and delivers higher levels of horsepower and acceleration gains for high-performance gas and diesel vehicles. Some AIRAID MXP Air Intakes start with a replacement one-piece roto-molded air box that addresses the shortcomings of the restrictive factory design. Housed inside the air box is an AIRAID premium air filter for outstanding air flow and filtration. Air is directed through a new air intake tube constructed of cross-linked, high-density polyethylene that is designed using extensive computer modeling to maintain proper mass air flow readings and calibration. Many MXP Air Intake Systems have a built-in velocity stack, which further promotes airflow. What this all means is that you get a simple-to-install, yet extremely sophisticated system to increase air flow while maintaining proper air-to-fuel ratios, thereby eliminating the need for recalibration after installation. Just bolt it on and go! Some AIRAID air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Review: Not perfect, but works great! - Received the kit in a well protected package. Hardware bag was missing the nylon 3/8" barb for the oil breather line. The manufacturer overnighted a new one, and the install went fairly smooth. Trimming the plastic Toyota shroud was a surprise, but wasn't difficult. Overall the new sound is deeper than most cold-air intakes on V6 Yotas, with most of the new power showing up in the top end of the Tach.

### ⭐⭐⭐⭐ It fits
*by J***R on January 13, 2025*

It fit just fine. Everything was in the box. However, the filter was very difficult to get it, its too long for the box. I will be ordering a filter that is slightly shorter in the future.
