Product Details

If you're looking to get more air into your 2016-2018 Ford Focus RS, this Injen SP series cold air intake is designed to help your engine breathe deeper. This system replaces the stock airbox and intake piping with a smooth, uninterrupted path for air, aiming to increase horsepower and torque.

The intake tube is constructed from 6061-T6 aluminum, which offers a smooth flow path. Injen has developed this system with their patented MegaRam and Air Fusion technologies, which they say helps tune the intake for safe power gains while maintaining proper air-fuel ratios. It includes a custom heat shield that seals against the hood to block engine heat, while still allowing the filter to draw in cooler air from the front of the car. The kit uses the factory air inlet ducts for optimal airflow.

This Injen intake comes with a serviceable SuperNano-Web dry air filter for good filtration and airflow. You can expect a more aggressive and throaty engine tone under acceleration. Installation is a direct bolt-on process with no modifications to factory components required. Injen backs this intake with a limited lifetime warranty.
