The Radtec intercooler is a direct replacement for the original OE intercooler with no cutting to the body or trim required. We tested several different core designs and found that a high grade fin and tube design was by far the most efficient, in our test we found that bar and plate cores that are available would cool okay on the first dyno run and would give a drop in air tempeature, however this core design would suffer from having extremely poor recovery rates and when you run on the dyno for 4 or more times would drop dramatically in performance.The Radtec intercooler uses by far the best intercooler core available and is unmatched by any of the competition, this is due to the companies on going supply to supercar and high end motorsport.
