M133 Intercooler Upgrade – CLA45 GLA45 AMG Dual-Pass Cooling Kit

Stop Heat Soak from Killing Your Boost – Keep Full Power Lap After Lap

Cooler charge air = no timing pull, consistent power, and that addictive M133 pull every time. Upgrade your CLA45 or GLA45 AMG now.

The factory M133 intercooler can't keep up under hard driving — heat soak sets in fast, pulling timing and robbing horsepower. This BenzUnited dual-pass intercooler fixes that with a massive core, better airflow, and proven cooling for street, track, or hot Burbank summers.

🔥 Why This Intercooler Wins

• 30% Larger Core – More surface area + volume crushes heat compared to stock.
• Dual-Pass Design – Air spends longer in the core for deeper cooling and lower IATs.
• 10%+ Lower Intake Air Temps – Real-world drop keeps timing aggressive and power consistent (no more fade on repeated pulls).
• Reduced Flow Restriction – Faster turbo spool, sharper throttle, better boost recovery.
• TIG-Welded Aluminum Construction – Built tough for high-boost tunes and daily abuse.
• Direct Bolt-On – Uses factory mounts — no cutting, no drama, install in a weekend.

❄️ Factory vs. Upgraded: The Difference You Feel

Stock intercooler heats up quick → timing retard → power loss. This upgrade keeps IATs stable so your ECU doesn't pull back — especially crucial with tunes, downpipes, or track days. Pair it with your intake for max results on the way to 500+ whp.
