The one thing everyone should bare in mind is the fact that all the manufactures of the RS500 intercoolers say there's is the best, when in many ways they are all the same, it's been proven so many times before. It's so easy to set a compamy up now days and say we do the best products. If you don't want to pay too much for a cooler just get the best deal you can find, if your looking for something that's been proven in motor sport to be the best all round cooler get a Pace one. Just consider how long Pace have been around for, they must be doing something right and again the fact that most motorsport folk use them speaks volumes. The consistancy of quality has also been proven over the years and the after sales service is second to none.
