CSF High-Performance Stepped Core Intercooler for BMW F87 M2 / F3X / F2X (N55)
TAG Motorsports is pleased to offer the CSF High-Performance Stepped Core Intercooler for the BMW F87 M2 / F3X / F2X (N55).
The CSF N55 Intercooler's Stepped Core Design maximizes surface area contact and internal intake air-flow volume. The Rounded Front Face Bar/Plate Design optimizes airflow through the core and is a true "Drop-in Fit" Plug-and-Play Design. In testing the CSF Intercooler showed Intake Air Temperatures (IATs) that were 38 deg F (21 deg C) lower than factory after just 3 consecutive pulls from 4k RPM to 5.8K RPM. In that test, the CSF Intercooler maintained stable IATs. While most intercoolers don't offer immediate performance gains without increasing boost pressure, the CSF Intercooler shows an increase of 15-20hp on stock N55 Powered BMW's and 25+hp on modified examples.
