RD Series
Injen® - RD Series Air Intake System
RD Series

The Injen RD series is a cold air intake system for the enthusiast craving mid-range power. The intake tube is strategically placed behind the front bumper where it can take in cooler, denser air. The cool air then flows to the engine through a fee-flowing aluminum alloy intake tube. Cooler air contains more oxygen for more complete combustion, as a result you will gain more horsepower.

Key Features:

• Delivers more oxygen to the combustion chamber by drawing in cooler air
• Custom designed and engineered to deliver maximum power for each specific vehicle
• Improves acceleration and fuel economy
• Every system includes the Injen EA Nanofiber dry air filter
• Mandrel-bent 6061 aluminum for smooth airflow
• Street legal in all States

SP Series
Injen® - SP Series Air Intake System
SP Series Intake by Injen

The SP Series is a Short Ram air intake system which features Injen’s patented MR (Mega Ram) Technology. MR Technology allows this system to attain increased intake airflow and performance while maintaining a safe air/fuel ratio. Injen steps down the diameter of the intake tube where the Mass Air Flow (MAF) sensor mounts, enabling the sensor to detect airflow within established parameters. The engine control computer can then maintain the proper air/fuel ratio and optimize horsepower and torque. Simply put, MR Technology tunes the intake system to avoid the necessity of recalibrating the MAF sensor, and prevents your engine from running too lean or too rich. With MR Technology, Injen created “The World’s First Tuned Intake System”. It delivers optimum performance with a factory safe air/fuel ratio.

Key Features:

• Improves airflow into the engine
• Increases horsepower
• Improves acceleration and fuel economy
• Easily installs under the hood
• Every system includes the EA Nanofiber dry air filter
• Mandrel-bent 6061 aluminum for smooth airflow
