More Air, More Power: The CTS-IT-270 Intake for VW/Audi MQB Models
If you're chasing more horsepower and a sharper throttle response from your MQB-platform VW or Audi, one of the simplest and most effective upgrades you can make is a performance intake - and the CTS-IT-270 from CTS Turbo is one of the most popular options on the market.
What Is the CTS-IT-270?
The CTS-IT-270 is a 3.5" cold air intake system engineered specifically for the MQB chassis shared by several of VW and Audi's most popular performance-oriented models. It's built to work with the factory air scoop and a sealed airbox, channeling cold outside air directly into the engine rather than pulling warm air from the engine bay.
At the heart of the system is a 3.5" high-flow air filter with an inverted cone design, paired with a CNC mandrel-bent aluminum intake pipe. The larger diameter and smooth bends reduce turbulence and restriction compared to the factory intake tract, which is engineered more for noise reduction than airflow.
Fitment: Know Your SAI Setup
One important detail for customers (and something worth calling out clearly on your product page): the CTS-IT-270 comes in two versions depending on whether the vehicle has secondary air injection (SAI).
- CTS-IT-270R - for MQB vehicles with SAI, including the MK7/7.5 Golf, GTI, GLI (2019+), Jetta GLI, and 8V Audi A3/TT.
- CTS-IT-270R-1 - for MQB vehicles without SAI, including the MK7/7.5 Golf R, Audi S3, and Audi TTS.
Getting this distinction right matters - installing the wrong version can leave a customer with fitment or emissions-component issues, so it's worth prompting shoppers to confirm their SAI setup before checkout (a quick note or fitment quiz on the product page can save a lot of return headaches).
Why Customers Upgrade
A few reasons this intake tends to be a go-to first mod for MQB owners:
- More horsepower and torque across the power band, especially noticeable on tuned or modified vehicles that need extra airflow to support the added boost.
- Improved throttle response thanks to reduced intake restriction.
- Straightforward DIY install - the kit includes all necessary components, making it accessible even for owners without a shop.
- Aggressive intake sound under acceleration, without crossing into obnoxious territory at idle or cruise.
Who It's For
This intake is particularly well suited to owners who've already started tuning their car (stage 1/2 ECU tunes, downpipes, etc.) and need the extra airflow to match increased boost demands - but it's also a solid standalone upgrade for anyone wanting a bit more response and a better induction note from a bolt-on part.
The Bottom Line
The CTS-IT-270 is a well-regarded, purpose-built intake for the MQB platform - backed by a 12-month manufacturer warranty against defects. For shoppers browsing your store, the key decision point is simple: confirm SAI or non-SAI fitment, and they're set up for a straightforward bolt-on power gain.
