Description
The Mishimoto MMAI-CLA45-14BK is a dedicated performance air intake system engineered specifically for the 2014-2019 Mercedes-Benz CLA45 AMG 4Matic. Built around a co-molded silicone turbo inlet hose with a CNC-machined port block for the factory sensors and breather lines, this cold air intake pairs a smooth-contour hose design with the Mishimoto High-Flow Oiled Air Filter to unlock measurable gains without touching the factory tune.
This air intake system was created to solve the restriction found in the factory 3-in intake tract by replacing it with a 4-in high-flow filter capable of flowing up to 2,000 CFM. The result, on the dyno, was up to 20 whp and 17 wtq at 5900 RPM. As a cold air intake, it’s engineered to work safely with the stock ECU tune and won’t push air/fuel ratios out of range under load, so drivers get a genuine air intake filter upgrade and an aggressive turbo spool and BPV tone without sacrificing drivability — whether you’re commuting through city traffic or chasing that cool air intake growl on the highway.
Vehicle Applications
This Mishimoto cold air intake is a direct fit for the 2014-2019 Mercedes-Benz CLA45 AMG 4Matic. It reuses the stock intake duct at the front of the vehicle to channel cool outside air into the enclosed airbox and onto the Mishimoto filter, and it installs without removing the front bumper or splash guard.
