Overview

The APR Closed Carbon Fiber Intake System is an attractive, high-performance upgrade designed to increase performance by letting the engine breathe more freely. Performance is optimized by improving mass airflow through the system, while also adequately filtering the incoming air. The system provides a direct airflow path through the system to the filter, and removes the rubber inlet snorkel, which has been known to collapse under load, and devastate power deliver. Expect increased horsepower, torque, sharper throttle response, enhanced fuel economy, enhanced engine sound, lower intake air temperature (IAT) and a more attractive engine bay! Lastly, 3.0T Supercharged engine customers can take advantage of a larger rear charger inlet pipe, which maximizes mass airflow, and removes a factory sound dampening resonator. Power Gains Using the upgraded air box alone, the 3.0T engine picked up 11 AWHP, and 15 AWHP when adding the rear inlet pipe. This was achieved at only Stage 1 power levels. As airflow requirements increase, so does the potential for more power. Likewise, on the 4.2L FSI V8 we measured 10 HP through the rev range on an otherwise stock vehicle.

Features:

  • Increased horsepower and torque
  • Better throttle response
  • Enhanced engine sound
  • Pleated cotton gauze filter
  • Closed carbon fiber system
  • All mounting hardware included

Perfection in a top
Color: Black, Size: Large
This top is one of my favorites, so I ordered it in another color. I wear them often because they’re perfect for spring. The top hits at my hip, and the sleeves cover my upper arms, which I like. The cut is flattering and cute. The material is substantial and it drapes nicely. I find it true to size. Any kind of necklace looks great with the neckline.

It's okay
Color: Dark Green, Size: XX-Large
It may be my build but the shirt just does not look good on me. I like the color. It is comfortable, just does not look good on. Oversized look.

Color not as pictured
Color: Purple, Size: Small
Love the top but the color is not even close to what is pictured. Ordered purple, the package label says it's purple, but it is bright hot pink.
