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

Great toilet paper but it needs to be individually wrapped
Size: 24 Double Rolls (2 Ply)
This toilet paper is soft and comfortable. I have tried different brands of bamboo toilet paper and a lot of them are too rough or sometimes they can leave lint behind (although the lint in general is not as bad compared to regular toilet paper). This toilet paper doesn't leave lint behind and it isn't rough on my skin. Although they seem super thin, they absorb very well and I don't have to use as much toilet paper. Overall, the quality is good and they function great. There was another brand I was using, but they went up in price by a lot. I decided to give this one a try. This is a good value for bamboo toilet paper. However, I wish the toilet paper rolls were individually wrapped for hygienic purposes. It doesn't come in smaller packs inside the big pack like some brands may do. Once it's open, all 24 rolls are exposed.

Good TP
Size: 9 Mega Roll
Nice paper. It doesn't have lint like other papers. Fairly strong for natural TP. It is not economical for larger families though. I would buy it for a 2-3 person household. It's not super-soft, but it's doesn't feel cheap.
