PERFORMANCE DESIGN

POWER YOU CAN FEEL

IE engineers have meticulously crafted every millimeter of this intake system, utilizing intricate shapes and angles to minimize turbulence and maximize internal volume. All restrictions are eliminated through performance optimizations, increased airflow, a generous filter surface area, and heat protection for maintaining low intake air temperatures (IATs). This unleashes the true potential of your engine tunes and hardware upgrades to deliver the most performance enhancements possible.

SINGLE PIECE AIRBOX

STYLE & RELIABILITY WITHOUT COMPROMISE

Enjoy the style and worry-free operation with our seamless one-piece airbox design. Unlike competitor multi-sectioned airboxes, our approach eliminates the risk of air leaks, complicated installation, rubbing noises, and parts loosening over time while maintaining the smoothest internal airflow path.

UNIQUE SOUND

ENJOY YOUR THROTTLE PEDAL

Sound is as integral to your driving journey as power. Immerse yourself in the addicting symphony of turbocharger spool, engine throttle, and diverter valve noises that resonate from your twin-turbo RS engine. Unlike the factory airbox that suppresses all sound, our intake system embraces the excitement with a refined and exhilarating audial experience that perfectly complements the enhanced performance of your build.

DUAL AIR-ZONES

AIR SUPPLY FOR ANY POWER GOAL

Our carbon airbox is equipped with multiple air supply avenues to support various power and build levels. The front and expansive air inlet captures outside high-pressure airflow and acts as a ram air design. Additionally, the filter plate louvers draw in extra air as required from the low-pressure zone below the intake. These dual zones provide an unrestricted air supply across the entire filter, eliminating power limitations for even the most extreme builds.

VELOCITY STACK

UNINTERRUPTED POWER

Uncommon in consumer-level applications, our integrated velocity stack strategically amplifies and smooths flow dynamics at a vital point as air enters the charge system. This advanced design element provides a gradual reduction from the substantial 5" air filter to the smaller turbo inlet. By precisely controlling this crucial transition, our intake system accommodates increased turbocharger and engine airflow demands with minimized drag and power-robbing turbulence.

TECHNOLOGY DRIVEN

QUALITY IS IN THE DETAILS

Our team of experts utilize cutting-edge 3D scanning tools and software to capture the precise dimensions of your vehicle's engine bay, grille, bumper, and hood. These high-resolution scans create an exact digital duplicate, enabling our engineers to harness every inch of available space with utmost precision. By leveraging this digital environment, we ensure a flawless design with the perfect style, fit, and feel.

PERFORMANCE VALIDATION

The IE Performance 2.9TT Air Intake System has been power tested to deliver impressive gains of up to 28HP and 26ft-lbs on tuned engines (with stock turbos)! Feel the surge of performance as you take command of the road, leaving ordinary RS5 and RS4s in the dust.

FLOW BENCH TESTING

Back-to-back flow bench results show constant and consistent CFM gains of up to 27.75% CFM over stock! This increase in flow details the intake design's efficiency over the factory parts and capability to provide any required airflow demands from ECU tunes and hybrid turbocharger upgrades.

The above gains are a result of various design details:

  1. The 5" air filter surface area and increased air volume improve turbo efficiency.

  2. The internal velocity stack provides a low-turbulence transition from the filter to the inlet.

  3. Carbon airbox high & low-pressure zones channel low-temp airflow quickly to the engine while protecting it from radiant engine heat.

A Clear Path Through Estate Planning
Format: Kindle
I went in expecting to feel overwhelmed, but this book flipped that fast. It is a game-changer with so much detail, you'll have a solid understanding of living trusts and how you and your family will benefit. The biggest win for me was finally grasping how to properly move assets into the trust without second guessing every step. It walks you through real scenarios like blended families and uneven inheritances in a way that actually makes sense. I also liked the practical worksheets and ready-to-use documents that keep you moving instead of stalling out. By the end, I felt confident making decisions I had put off for years. It turns a confusing process into something clear, doable, and worth finishing.

A practical guide that makes a complicated process feel managable
Format: Kindle
I picked up this because estate planning always felt overwhelming, and I wanted something I could actually follow. This guide does a solid job breaking things down into clear steps, especially when explaining how to set up and fund a living trust and what documents are needed along the way. I appreciated the focus on real situations, like blended families, choosing trustees, and avoiding conflicts. The included forms and worksheets made it feel more hands-on, not just theory, which helped me better understand how everything fits together. At times, the amount of information felt a bit dense, and I had to reread certain sections to fully grasp the legal details. Still, the structure is logical and keeps you moving forward. Overall, I found it useful and informative. It gave me more confidence around estate planning, even if I would still double-check some steps before finalizing anything.

A great tool for learning about trust funds.
Format: Kindle
This is an easy-to-read book that guides one through the process of what to do upon death. I went through this recently with my family and wish that I had this book at the time. Coincidentally, I'm meeting with an attorney for exactly this reason (serendipity?). The book clearly defines the common lingo used throughout the process and identifies principal participants, pitfalls, and a general knowledge of how best to execute one of the most important documents of our lives.

Valuable information in an easy to understand book
Format: Kindle
This book makes the whole process of setting up a living trust feel way less scary than I expected. The step-by-step instructions are written in plain language, so you don't need a law degree to follow along. I really appreciated the ready-to-use forms and worksheets because they save a ton of time and take the guesswork out of getting started. It also covers tricky situations like blended families and second marriages, which a lot of other guides seem to skip over. If you've been putting off protecting your assets because it feels too complicated, this book is a great place to begin.
