The OEM manufacturers spend a lot of time reducing turbo noise at the expense of horsepower. By letting the turbo ingest all the cold air it needs, the Alpha Mercedes-Benz CLA45 AMG Carbon Fiber Performance Intake System boosts power significantly. In addition, it allows you to hear the turbo spool up which is something you as an enthusiast can appreciate.
The engineering team immediately noticed a considerable level of restriction in the stock intake system and solved the problem by designing a smooth transition to a much larger filter. By upgrading the size of your 2.6″ factory inlet filter to a robust 4″ design, it drastically reduced the high pressure drop – a sure indicator that your stock intake filter is choking your 2.0L M133 turbocharged engine. By simply installing this air intake upgrade on its own, you’ll be rewarded with a 20+HP increase!
