MAD-013 MAD BMW E CHASSIS 5″ HD INTERCOOLER N54 N55 135 1M 335 (STEPPED CORE) MAD-1013

MAD 5” Stepped Core Intercooler – BMW 135i / 335i / 1M (E-Chassis)

Cooler IATs. More Power. OEM Fitment.

Upgrade your factory intercooler to the MAD 5” Stepped Core Intercooler and keep your intake temps low — even under heavy boost. The stock BMW intercooler simply isn’t designed for high-performance applications and will quickly heat soak under tuned or spirited driving conditions.

MAD solves this with a high-efficiency 5" stepped core, engineered with a high fin density to maximize airflow and cooling capacity without increasing pressure drop. It’s the ideal intercooler upgrade for Stage 1 builds and fits perfectly in your factory location — no cutting, trimming, or modification required.

Weighing only 22 lbs with compact dimensions of 21" x 8.5" x 5", this intercooler offers the best cooling-to-weight ratio in its class.

• Direct Stock Replacement – 100% bolt-on, no cutting required
