What you get

• EVO3 stepped front mount charge air cooler - Part No. 200001113
• Reinforced 70 mm silicone couplers with clamps and alloy adapter
• Fitting hardware and instructions
• N55 stainless steel turbo downpipe with 200 CPSI motorsport catalytic converter

Why this package

• Massive cooling upgrade - stepped core measures 510 x 303 x 180 mm with a 20.65 litre volume, offering a 162 percent larger frontal area and 182 percent more internal volume than the factory cooler. Lower intake air temperatures help maintain consistent power pull after pull.
• High efficiency construction - tube and fin core with internal turbulators and CFD optimised cast alloy end tanks for excellent flow and heat rejection. Anti corrosion coating supports long term performance.
• Strong, simple plumbing - factory clip style connectors are replaced with robust 70 mm hose connections and heavy duty silicone couplers to cut pressure drop and improve reliability under boost.
• 200 cell sports cat downpipe - made from 1.4301 T304 stainless steel for durability. The high flow catalyst slashes back pressure, eases thermal load on the turbocharger and helps the engine breathe for improved throttle response and torque.
• Ready to install - designed for a precise fit with only light trimming to the plastic cooler support typically required. Supplied with brackets, fixings and clear instructions.

Fitment - N55 engine only

Compatible with selected E series models using the single turbo N55:

• BMW 135i E82 and E88

Real results you can feel

This is the go to front mount cooler and catted downpipe combination for reliable, road legal performance on E8X and E9X N55 platforms.
