CTS Turbo High-Performance Intake Kit for Mercedes-Benz M133 A45/CLA45/GLA45 AMG

Engineered for AMG Performance

Imagine launching from a stoplight, your turbocharged AMG responding with even sharper urgency and an intoxicating induction sound that announces your presence. This precision-engineered intake system replaces the restrictive factory intake tube while retaining your factory airbox, delivering maximum airflow exactly where your M133 engine craves it most.

The massive 5-inch high-flow air filter is one of the largest available, designed specifically to feed your hungry turbocharger. The result? Immediate improvements in throttle response, noticeably sharper acceleration, and power gains that become even more impressive when paired with ECU tuning—up to 17 horsepower on tuned engines.

Smart Engineering, Maximum Results

CTS Turbo understands what AMG owners demand: performance without compromise. That's why this intake system utilizes your factory ram-air airbox—maintaining optimal air temperature management while eliminating restrictions. The custom filter adapter seamlessly integrates the oversized filter, creating a direct path for cool, dense air to reach your turbocharger.

Unlike cheaper alternatives that cause check engine lights or sacrifice reliability, this system is engineered to work flawlessly with your AMG's sophisticated engine management. No CEL codes, no compromises—just pure performance enhancement.
