Introducing our Turbo Inlet Pipe (TIP) for the 2002-05 Audi A4 (B6).

Ease of Installation: (1 Easy, 5 Hard) 1
Key Features:
  • Made from high grade 6061 aluminum piping.
  • 100% TIG welded.
  • Mirror polished finish or optional Type III Hard Black Anodizing (for stealth) finish.
  • Increase throttle response.
  • Increase turbo spool up.
  • Factory rubber turbo inlet hose is prone to "collapse" during high boost, causing restriction and robbing top end power.  Our full aluminum metal pipe prevents this.
  • Compatible with K04, GTRS and similar turbo upgrades.
  • Compatible with the factory 1.8T MAF sensor or upgraded 3" MAF sensors.
  • Maintains ALL factory components.
  • Includes all hardware needed to install.
  • Limited Lifetime Warranty.

As the turbo begins to spin and build boost pressure, the vacuum pressure created before the turbo starts to increase as well.  With more boost, this vacuum pressure increases exponentially.  The factory turbo inlet hose sits right before the turbo and is made of flexible rubber.  With vacuum, it starts to "collapse" into itself (imagine a full ballon getting the air sucked out).  Thus, the inner diameter of the factory inlet hose starts to shrink and get smaller.  The more boost pressure, the more vacuum is created in front of the turbo.  This creates a big problem as at peak boost, the factory inlet hose's inner diameter is at its smallest (due to highest vacuum), however at peak boost, it needs to be at its largest size to feed air to the turbos.  The turbo starts to choke as it is having a more difficult time pulling air through it (due to the collapsing factory turbo inlet hose) and thus slows down the turbo spool time, negatively affecting throttle response and potentially decreasing top end power potential.  With factory boost pressures, this is not big problem as the factory turbo inlet hose is designed to at least withstand the vacuum pressures produced.  However, with increased boost pressures with chip upgrades and even turbo upgrades, this problem will begin to surface.  On some instances, the factory turbo inlet hose may completely collapse and suffocate the turbo, causing the engine to run extremely rich and stall the engine.

Our turbo inlet pipe (TIP) was designed to solve this issue completely.  Made from 6061 aluminum metal (lightweight, yet strong) the diameter of the piping stays the same regardless of the vacuum pressures present and thus impossible to collapse.  This ensures that there is sufficient airflow to the turbos, especially at peak boost levels where vacuum pressure is at its peak as well.  The benefits?  Faster spool times, increase throttle response and higher sustained power levels.

Compatible with the factory K03 turbos as well as the K04 and GTRS turbo upgrades.  Our TIP is also designed for versatility as one pipe is compatible with ALL of these turbos (requires changing of the silicone hose size).  Please specify which turbo you have when ordering to receive the correct silicone hose size.

Compatible with the factory 1.8T MAF sensor (2.75") or upgraded 3" MAF sensor. 

Three different finishes are available: mirror polish, brushed and Type III Hard Anodized Black.  Mirror polish, the standard finish, is ideal for those who want to brighten up the engine bay.  The brush finish is a bit lower profile yet slick.  The Type III Hard Anodized Black finish is ideal for those who do not want the extra attention.  Extremely stealthy, it will blend into the engine bay and look like the factory turbo inlet hose.  The Type III Hard Anodized finish also has an added benefit of hardening the aluminum tubing for even more strength.

Quality is very important to us. We do extensive R&D as well as beta testing to ensure this (as some of you may already know, waiting for us to release the production units). We only release our products once we feel we have reached perfection. Our TIPs come with beaded edges.  This beaded edge prevents the TIP from slipping off the connection.   We include detail instructions, and ALL parts needed for installation. All our products are backed with our Limited Lifetime Warranty.

Great replacement to my older 5.1 Yamaha receiver.
Style: 7.2 Receiver
Great replacement for an older Yamaha. My previous unit lasted 10 years and I see no reason why this new one wont last another 10. Familiar features and setup to other Yamaha receivers. Zero issues with setup and contrary to others, you can use all the features without the app. While the app does add some features for streaming, the unit is fully usable as a receiver for movies, surround, etc. without the app. Overall the sound improvement is spectacular, the high slew rate really makes a difference and DSP much improved over the older 10 year old unit I had. Solid hardware, solid setup and while I'm not about Brand Loyalty, the Yamaha still had better features, reviews and quality than the other major brands. I would have no issue recommending this to unit to anyone. Remember, these units are about the sound they offer, not the the wiz bang features you see in some other units. Reliable hardware, reliable sound and a rich feature set makes this unit a no brainer.

Great receiver for money!
Style: 7.2 Receiver
I got this to replace my lackluster Onkyo TX-NR6050 I purchased from Costco. Three areas stand out for me with the Yamaha receiver: 1: Audio, movies sound great, dialogue is clear. Action scenes are impactful and dynamic. 2: Picture quality, bright, vibrant and beautiful colors from my PC and from my Firestick. 3: Ease of use, out of the box ready to go. Menu is dated (no gui really just an overlay, which is fine by me). Renaming inputs, adjusting speaker settings and setting EQ preferences super easy. Took about 20-25 minutes to fully setup. In those 20-25 minutes I was already way ahead of the Onkyo. Great value for the price! Volume is very easy to set! Still have to test PS5 performance, Bluetooth connectivity, USB settings, WiFi and a few other items. I’ll probably end up buying a Blu-ray player since this was so easy to setup! Or maybe use my PS5/Xbox One :)

Solid 2 Zone Receiver / Amplifier - Excellent video and Audio
Style: 7.2 Receiver
I purchased this Yamaha to replace the 10YO previous version that no longer decoded SiriusXM. This new clean front panel design and much improved remote control are easy to use once installed. I have to say the only complexity I have run into is connecting 3 smart devices together - NVIDIA Shield PRO Streaming Box, RX V6A Receiver and LG OLED TV via HDMI chain from Streaming to Receiver to TV with no audio or video passing through the TV first. The only issues that result is getting all 3 to play nicely when switching on and off via a single (NVIDIA) remote control. It is nothing short of fantastic to be able to have such a simple remote control all three devices for the most common functions. Only specialty settings require a specific remote. However it becomes an issue of chicken or egg - as control messages to go on or off are carried by HDMI and the power sequence becomes complex - with options to turn on or off IF ... THEN... for all 3! Otherwise the receiver has been a dream to finally restore sound to several rooms in our home from SIriusXM and now several other sources as well, I'm thrilled with the features, new MusiCast control and ease of operation once installed and properly paired for single remote operation. I plan to have this around another 10 years and enjoye the excellent 4K video upscaled by the NVIDIA device and handled beautifully by the receiver to drive the TV in rich color and great 5 Channel Sound.

A great A/V receiver at a great price. Too bad Amazon Customer support is horrible.
Style: 7.2 Receiver, Style: 7.2 Receiver
Pros, 1. A 7.2 channel A/V receiver that can do 5.1.2 Atmos. It also support DTS-X as well. 2. 200 watts total power. Don't let that fool you. It powers my 5.1.2 speaker setup far better than my previous Onkyo TX-NR5100 that's supposed to 80 watts per channel. Also sounds a lot better and clearer. 3. 7 HMDI inputs and 1 HDMI eARC output that support 8k/60hz and 4k/120hz with Dolby Vision. Additional speaker inputs for extra zones for run into other room. 4. Uses banana plugs for easy installation. 5. Has both WIFI and Bluetooth. Also includes an AM/FM antenna as well as a speaker calibration mic. 6. Has two RCA subwoofer input jacks for dual sub units. 7. Very well built and very sturdy unit. Looks very nice. 8. Includes an extremely nice remove control. Cons, 1. It's not the easiest to setup nor the most user friendly. Once setup you should be good, but it's a matter of the learning curves. 2. Make sure you get the latest firmware. You may get unlucky, get an older unit, wonder where all the features are at and why they're not available. 3. Lastly Amazon customer support is utterly horrible and useless. I order this produce and later that day they offered a discount. I called up customer support for a price match and THEY REFUSED TO DO IT!!!! I ended up canceling the order and reordering at the better price and Amazon ended up losing money because they were getting ready to ship the first order. LEARN TO PRICE MATCH LIKE YOUR COMPETITION!!!!!!!! I have this hooked up to my computer for movies and gaming, it works great because of the 120hz pass through. Other than horrible customer support the receiver is great and otherwise I'd have rated it a 5 star. I took one star for the customer support.

Review
Style: 7.2 Receiver
So far I’ve been very pleased with the unit although I only use it for powering two large front 4 ohm external speakers while listening to music streaming on apps in the TV. Unlike AVs from both Denon (who I believe has the best tech support) and Onkyo that I returned, when I turn on my Sony Bravia TV with settings enabled for eARC, the Yamaha unit does not automatically turn on and subsequently switch sound to the external speakers. Perhaps it’s possible but it’s not something that I wanted. Additionally, I came to learn that both Denon and Onkyo are owned by the same parent company, which may explain their common behavior. However, the Yamaha receiver does automatically switch to the external speakers when I power it on and I am able to control the AVR volume with my TV remote control. Additionally, with the settings I have on the TV and AVR, when I turn off the AVR, the sound automatically switches back to coming from the TV speakers, and the TV does remain on. Again, something I want to happen. In general, I’ve found that these devices are very complicated with their myriad number of settings on both the TV and the AVR, and it can be very challenging to properly set them. I’m retired now but my undergraduate degree is in electrical engineering from an Ivy League school at a time when we used slide rules to do the mathematics. I would say that it’s not easy to learn how to use the devices with eARC. If you only want to improve the TV sound, I'm guessing that's it's a lot simpler to use a sound bar. In my case, I've had large and expensive 4 ohm front speakers that I wanted to continue to use (my old AVR does not have any HDMI connections) so a sound bar was not an option for me.
