Injen 11 BMW E82 135i (N55) Turbo/E90 335i Polished Tuned Air Intake w/ MR Technology, Air Fusion

When you open the hood of your 2011-2013 BMW 135i, you want to see parts that look as good as they perform. This Injen SP Series Short Ram Air Intake system is designed to do just that, giving your N55 turbocharged engine a breath of fresh air. What you get in the box is a complete kit: polished 6061-T6 aluminum intake tubing, a front air scoop, a fully serviceable Injen SuperNano-Web dry air filter, and all the necessary hardware and instructions for installation. This system is built to help your engine breathe deeper, potentially leading to more horsepower and a more aggressive engine tone under acceleration.

Injen has been tuning intakes for a long time, and this system uses their patented MR Technology and Air Fusion processes. These aren't just fancy names; they're designed to optimize airflow and maintain a safe air-fuel ratio, which is crucial for engine health and performance. The smooth, uninterrupted path created by the polished aluminum tubing helps reduce restrictions compared to the stock intake. The SuperNano-Web dry filter is designed for increased airflow while still providing good filtration, and it's serviceable so you can clean and reuse it for the life of the intake. This intake is designed to be a direct fit, meaning no additional tuning is required after installation, and it's made in Pomona, California.

This Injen intake is designed to give your 135i an aggressive, throaty tone when you put your foot down, making the driving experience more engaging. While this specific kit is for the 2011-2013 135i, Injen also offers this system for certain 335i models. The kit includes a limited lifetime warranty from Injen Technology, reflecting their confidence in the build quality.
