Renault Megane RS225 R26 R26R Intecooler
 
Designed as a straight swap for the standard Renault Unit, the new Pro Alloy R26 Intercooler requires no additional kit parts as it uses the standard Renault fixings but benefits from a significant increase in surface area and internal flow.
Renault Specialists RS Tuning carried out some detailed back-to-back testing, comparing the new Pro Alloy intercooler against some of the other popular intercoolers available for the R26. See Results of the test below

Megane R26 Intercooler Comparison Test By RS Tuning
The test vehicle used was a fully forged R26 with cams, hybrid turbo, fuel system and mapped to run open loop boost control on the stock ECU, this way the ECU will NOT compensate and always run a fixed mapped value for waste gate duty cycle.
----------------------------------------------------------------------------------------
The car was mapped previously with the Forge 60mm intercooler so we tested that one first for a baseline.
Ambient Cell Temp 14.8 
Intake Temp before run 16.25 
After run 31.88 
Boost pressure 1.61 @ 1.62 bar @ 6000 RPM Logged on the intake manifold
