CTS Turbo Mercedes-Benz M133 A45/CLA45/GLA45 AMG Intake System

Made for the M133, not adapted to it

This isn’t a universal filter on a bracket. It’s built around the M133 engine, so it bolts in clean and the fitment is right. The kit runs a 5″ high-flow filter, one of the biggest you’ll find for these cars, on a custom adapter that gets rid of the narrow factory inlet. You get quicker throttle response, stronger pull up top, and a lot more turbo spool noise.

What you get out of it

• More airflow — the oversized filter removes the factory restriction
• Sharper throttle response
