Intercooler for BMW 1 Series

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

N54 Chargepipe and BOV Kit:

All of the tuning in the world is only as good as the weakest link. More boost in your 135/335 is great! But you will soon learn that some of the factory hardware is not up to the task of handling that extra pressure. One of the first things to fail and cause a boost leak are the factory boost diverter valves. This allows boost to "leak" out of the intake stream and a loss of power from the engine. This ECS Tuning chargepipe upgrade includes a blow-off valve in place of the factory diverter valves. The BOV is higher quality than the diverter valves and will exit intake air to the outside instead of putting it back through the turbo system (which will reduce strain on the turbos). This aluminum chargepipe is also much more robust than the stock plastic factory pipe and the connection to the throttle body is stronger, eliminating another failure point of the stock pipe.

Built-in 1/8" NPT ports allow you to run an additional methanol injection kit (bungs included if you don't want use the ports).

This is a complete kit that includes everything you need to replace the factory chargepipe and diverter valves -

powedercoat chargepipe
ECS Tuning blow-off valve
multiple BOV springs to suit your vacuum/boost needs
vacuum plugs for the stock diverter valve hoses
silicone hose connection to intercooler piping
all hardware and hose clamps with instructions
