Unlock the full potential of your turbocharged N54 or N55 engine with the Turner Motorsport Stepped Intercooler. Whether you're running higher boost, track days, or just spirited street driving, this direct-fit upgrade is engineered to dramatically reduce intake air temperatures (IATs) and improve charge air flow for consistent, reliable performance.
Cooler air is denser air, and that means more oxygen per cycle for better combustion and more power. The factory intercooler quickly becomes a bottleneck under increased load or in warm conditions. Turner’s stepped intercooler solves that by offering an 80% increase in frontal surface area and cross-sectional flow, helping your BMW stay cooler and pull harder.
Constructed with high-quality cast aluminum end tanks and a bar-and-plate core, this intercooler delivers superior cooling efficiency and reduced pressure drop, even under sustained high-boost operation. The black powder-coated finish offers a clean, stealthy appearance, while the etched Turner logos add just the right touch of motorsport style.
Perfect for:
E82/E88 135i, E9X 335i/335xi, E84 X135i, E89 Z4 35i/35is
Key Features:
Direct-fit upgrade for E chassis N54 & N55 engines
Durable cast aluminum end tanks
High-efficiency bar-and-plate design
80% increase in frontal and cross-sectional area vs. stock
90% increase in charge air volume
Substantially lower IATs for improved power and reliability
Reduced and more consistent pressure drop
Lightweight design (under 20 lbs)
Dimensions: 520mm wide × 210mm tall × 130mm deep
Stealth black finish with Turner-etched logos
If you're looking to push your turbo BMW harder, the Turner Motorsport Stepped Intercooler is the cooling solution that keeps your engine running strong—pull after pull.
Looking to upgrade your intercooler? This Phoenix Racing intercooler designed by Burger Motorsport is a great option that delivers better cooling, more power to the wheels, and allows you to hold that power longer during extended runs. A larger core and increased surface area dramatically improves cooling and reduces pressure drop. After extensive testing, this can allow your N54/55 powered BMW to gain around 10+peak wheel horsepower and during longer pulls and multiple runs, as much as 20-30whp over the factory intercooler.
Phoenix replacement intercoolers are a direct replacement for your factory intercooler and fully reversible. All required hardware is included.
Dimensions: 20" x 5.25" x 5.25"
