AMG A45 Stage 1

A45 Cold Air Intake (M133)

¥1,554.00 CNY

 

Take your Mercedes-AMG A45 to the next level with the ZAC Motorsport Cold Air Intake, proudly designed and developed in Australia. This intake is built to deliver real-world performance improvements, offering superior airflow, cooler intake temperatures, and sharper throttle response.

We’ve engineered this intake system to move the air filter away from the intense heat of the engine and turbos, ensuring only cooler, denser air reaches the engine. With zero restrictive bends, the CFD-optimized design enhances airflow efficiency, while the fully enclosed housing keeps unwanted heat out.

Key features include:

  • CFD-Optimized Design: Smooth, uninterrupted airflow for better throttle response and turbo efficiency
  • OEM Fitment & Finish: Direct fit for the A45, designed to integrate seamlessly with factory components
  • 75% Larger Air Filter: Dramatically increases airflow for more power
  • Performance Engineered in Australia: Proudly designed by ZAC Motorsport

Whether you're hitting the streets or the track, the ZAC Motorsport Cold Air Intake will help unlock the true potential of your A45, giving you noticeable gains in power and overall engine performance.

Possibly missing parts or poor design

I'm not sure if the kit I received was missing parts or if it's just a bad design.

Firstly, the heavy metal plate that connects the filter and the turbo inlet hose was difficult to mount. The original factory screws were made for plastic and could not be used with the metal plate; the plate itself wasn't threaded either, which doesn't matter, I suppose, as there were no bolts provided to secure it to the airbox. I had to use my own hardware for this.

Also, I was missing 2 worm clamps required to secure the turbo inlet pipe to the turbo and the airbox plate; these were not included. I was able to reuse one of the original clamps from my OEM inlet pipe, but had to source the other one separately, as the OEM one was not the right size for the new pipe.

Finally, the method by which the EVAP lines connect to the inlet pipe leaves a lot to be desired. There is absolutely nothing to help retain the lines in place other than the friction of the silicone itself. This is an unsafe way to attach these components, as it can easily introduce unmetered air into the engine, potentially causing damage. I have gotten a recurring check engine light because the EVAP line is not seeing the appropriate pressure drop at WOT due to not being adequately secured. I am hoping to remedy this by once again buying my own hardware (3 more worm clamps) to better secure those hoses and sensors and prevent leaks.

Overall, while I think the price for this intake is reasonable, it really should include all the hardware to complete the install and ensure the correct and safe operation of the vehicle with this aftermarket part installed.

Thanks for the detailed writeup - I'll touch on each point as these don't match what we typically see on this kit.

1) Filter-end clamps: Every filter ships with two clamps included, but it's possible one got missed. Did you only receive one (or none)?

2) Airbox adaptor plate: The factory plate for this application is aluminum with the same hole pattern as ours. We haven't seen a mismatch issue with the metal plate before (only occasionally with an earlier 3D-printed version, which is a different part). Could you send a photo of your OEM plate and the screws you tried? Want to make sure we're comparing the same part.

3) EVAP line retention: I want to flag one thing here - those fittings are barbed and designed to hold under the vacuum they see, and push-fit hasn't been an issue on this kit historically. One thing worth checking: did you remove the factory adaptor plate from the OEM rubber turbo inlet before installing our silicone pipe? If that plate is still in place, you'd end up with three hose connections but only two ports on the silicone pipe, which would explain both the fitment trouble and a real vacuum leak at WOT. If you want extra peace of mind either way, factory-style adhesive on the barbed fittings is a good option - I'd hold off on clamps there, since over-tightening a worm clamp on that hose can pinch or damage it.

I've previously run a K&N filter, then switched to an expensive well known brand air intake kit but when I found Zac's kit I made the switch again. Zac's kit is world's above the competition. This air intake includes a silicon intake from air box to turbo, ditching the restrictive plastic stock pipe, which the others don't. The giant air filter fits perfectly in the stock air box, the kit was super easy to install, and all parts are of a premium build quality.

After installing this intake the turbo definitely spools up quicker and there is a noticeable increase in power. The indication noise and turbo flutter sounds it provides are amazing too..Thanks Zac Motorsports!!
