CTS Turbo is proud to announce an official release of our new K04 Turbocharger Upgrade for B7, B8, and B8.5 Audi A4/A5/ALLROAD 2.0T cars.

This unit features a full-frame K04 CHRA installed into our proprietary, in-house designed compressor cover and turbine housing. Based on the turbo which comes stock on a MK6 Golf R, this upgrade kit is made to fit directly in place of factory Borg Warner or IHI turbo found in B7 A4, B8 A4/A5/AllRoad and B8.5 A4/A5/AllRoad 2.0T.

Our engineers designed the compressor cover and exhaust housing to work with the larger K04 CHRA, exactly how intended. While other manufacturers simply install a larger CHRA into a small factory-spec housing. Beware of these hybrid builds, they are not made to provide optimal flow for the larger turbine wheel and can lead to poor performance and premature failure.

High-quality castings are CNC machined to replace your factory turbocharger and do not require any additional parts to be installed. All you need to run this K04 Upgrade is a tune for your ECU.

To make installation even easier, we supply OEM gaskets and installation hardware.

Features:

  • CTS-spec K04 CHRA with heavy-duty thrust bearings
  • Billet compressor wheel (MFS – machined from solid)
  • K04-specific compressor and turbine housing. NOT A HYBRID!
  • OEM+ manufacturing tolerances
  • VSR high-speed balanced
  • Direct-fit factory replacement
  • OEM installation kit included
  • Compatible with any K04-specific tune
  • With supporting mods this turbo is capable of producing 350HP/340TQ on a 2.0T

Fitment:

  • 2006 – 2009 Audi A4 2.0T
  • 2009 – 2015 Audi A4 2.0T
  • 2009 – 2015 Audi A5 2.0T
  • 2009 – 2015 Audi Allroad 2.0T

Note:

  • Aftermarket High-flow catalytic converter recommended
  • K04-specific tuning required (B7 A4 required upgraded HPFP and fuel injectors)
  • Bracket on coolant line may require trimming on some models

Elegance and Practicality in a Lightweight Divider
Color: Mountains and Waters, Size: 4 Panel, Color: Mountains and Waters, Size: 4 Panel
Elegance and Practicality in a Lightweight Divider I recently acquired the 4 Panel Room Divider from the Furnnylane Store, opting for the Japanese mountainside print over the floral theme. Priced at $149.99, this piece not only promised functionality but also an aesthetic charm that piqued my interest. Upon arrival, the first thing I noticed was its impressive dimensions (63"W x 67"H), offering ample coverage for most standard spaces. Despite its substantial size, the divider is surprisingly lightweight, making it a breeze to move and adjust as needed throughout my home. The double-faced design is a standout feature, providing 100% blackout on both sides, which is ideal for privacy or blocking out unwanted light. This aspect was particularly appealing to me as I was looking for a solution to minimize nighttime light intrusion. The divider excels in this regard, effectively blocking and diffusing light to create a more comfortable sleeping environment. From a design perspective, the Japanese mountainside print adds a serene and picturesque element to the room. While the materials are not what one might consider artisanal, the overall look and feel of the divider are quite lovely, enhancing the room's aesthetic without overpowering it. The room divider's foldable design adds to its convenience, allowing for easy storage when not in use. It requires no assembly, which is a significant plus for those who prefer hassle-free products. The natural pinewood frame, free from chemical paints and non-toxic glues, aligns with my preference for safer, more environmentally friendly home decor. In terms of versatility, this divider has proven to be a multifaceted addition to my home. It serves not only as a practical room separator but also as a decorative piece that brings a touch of elegance and tranquility to any space it occupies. Overall, the 4 Panel Room Divider from Furnnylane is a commendable blend of form and function. Its lightweight nature, combined with the beautiful Japanese mountainside print, offers both practicality and visual appeal. While the materials may not be of the highest artisan quality, they do not detract from the divider's charm and effectiveness. This piece has been a delightful and functional addition to my home, and I would recommend it to anyone looking for an elegant solution to room separation or light blocking needs.

Nice room divider
Color: Colorful Landscape, Size: 6 Panel, Color: Colorful Landscape, Size: 6 Panel
I am pleased with this room divider. I was concerned that the art design might look blurry or cheap in person compared to online, but it doesn't. It looks really nice. In fact, I like it so much that I bought a second one as well. It arrived folded up - there is no assembly required - you simply unfold it and place it where you want. It's relatively light weight so it's easy to move. I also like that there is a different artwork design on each side. You have two choices; you can display whichever side you like more.

May cause respiratory issues
Color: Mountains and Waters, Size: 4 Panel
The painting on this panel is beautiful and quality has held up BUT I’m almost certain this contributed to respiratory issues. It was next to my bed for a year and I recently noticed it’s still shedding red/brown dust. The wood was clearly painted over and it makes me skeptical about the wood that was used. The panel itself feels like it’s made cardboard. If you’re sensitive or plan to place this panel in a main living area, I would not recommend
