i run a focus rs engine in a mk6 fez and run the standard chargecooler and custom rads

problem i have is once its sat in traffic around town the chargecooler gets warm very quickly and soaks the heat up from the tubular manifold

would a intercooler set up be better for me

what are the pros and cons of both systems??????performance etc???

obvisually water injection would be used on a intercooled set up
