The Cooling Experts
CSF has been building cooling systems for nearly 40 years. This isn't their first intercooler and it shows. The N55 intercooler uses their proven stepped core bar-and-plate design that maximizes surface area contact while optimizing internal airflow volume. It's the largest true drop-in fit intercooler available for this platform.
Real World Testing
CSF tested this in their in-house wind tunnel and on the dyno. The results are consistent - 38°F drop in intake air temps after three consecutive pulls from 4k to 5.8k RPM, and temps stayed stable. Most intercoolers don't show power gains on stock boost, but this one does. 15-20hp on completely stock N55s, over 25hp on modified cars. That's without touching the tune.
Engineered for Fit and Function
The rounded front face bar-and-plate design was developed using 3D scanning and rapid prototyping to ensure it uses every millimeter of available space. OEM-style quick-connect fittings mean installation is straightforward - true plug-and-play. No modifications needed to the car, fully reversible back to stock if you ever need to.
Built to Last
Bar-and-plate construction throughout. CSF backs this with a lifetime warranty on the core. Available in silver finish or matte black if you prefer the stealthier look.
This is the upgrade to do before you start turning up boost. Get the cooling sorted first, then worry about power.
