Overview
The APR K04 Turbocharger System is a drop in turbo upgrade that dramatically increases power. With this upgrade and accompanying software, expect power similar to a heavily tuned Golf R, S3, TT-S, and other high end vehicles, as the K04 comes standard on those vehicles. Transient response is lightning fast with minimal lag. Power comes on quick, and stays strong through the entire powerband. Best of all, the system is designed as a budget upgrade compared to larger turbocharger systems, and only requires minimal hardware, most of which is available to APR Stage 2 customers. Turbocharger: APR uses Genuine Borg Warner components. The heart of the system is a Borg Warner K04-64. The CNC-machined billet compressor wheel and stainless steel exhaust manifold are a substantial leap in technology, performance, and reliability over the factory unit. Unlike the off the shelf K04-64 unit, APR's unit is customized. We integrated the DV into the compressor cover, just like the factory turbo it replaces. In doing so, clutter and complexity is removed. The DV mounts to the turbo, eliminating several potential boost leak points. It's a simple and clean install. With many thousands of these units sold for more than a decade, we can confidently say these turbos are powerful, and reliable. Install hardware: We don't cut any corners with this system. All gaskets, nuts, bolts, washers, studs, and one time use clamps are included with this upgrade, making install as headache free as possible. Software: APR's Stage 3 K04 ECU Upgrade is included with this purchase. Please visit your applicable vehicle ECU upgrade page for more information about the software, including recommended and required hardware, power figures, and other details.
Features:
- Big power and torque gains
- OEM K04 drop-in turbo
- Genuine Borg Warner components
- DV integrated into the compressor cover
- High quality materials and components throughout
- ECU software included

It works!
Style: 1 to 1 IR Repeater
I’ve been wanting to use my DVD player more often, when I work at my desk, but it’s situated too far for the remote. This device works perfectly, now I can enjoy so many old DVDs without having to move or rearrange my whole setup.

So Much Fun! High Quality & Perfect Alexa Smart Integration.
Color: Black
I use these Govee RGBIC Light Bars every single day in my room, and they have completely upgraded the vibe of my workspace. If you want to add some serious personality to your setup, these are an absolute must.
The fit is perfect right behind my monitor, completely transforming the overall appearance of my desk area. I have them seamlessly connected to Alexa, so all I have to do is say, "Alexa, turn on my Govee lights," and they click right on. While you can use a remote control or the app, the voice activation makes them incredibly convenient.
It is just a lot of fun to play with the different settings. You can change the colors instantly to give the room whatever mood or feel you are in the mood for. The build quality feels solid, and after months of daily, continuous use, the durability is excellent with no flickering or dimming. It has truly added a new level of enjoyment and style to my office space.
PROS:
High-quality appearance that makes any desk or TV setup look professional
Tons of fun color combinations and dynamic mood settings
Flawless smart home compatibility with Alexa
Great durability for daily, long-term use
CONS:
There are so many features and color modes in the Govee app that it can take a little bit of time to learn where everything is, but it is worth it.

Cool light bars
Color: Black
Lights work great. Easy to install and connect to the app. Endless color options and they fit perfect on my desk. I stuck two of the behind my monitor and two on the side to make nice ambient light. I like that you dont need the app to turn on the lights.
