SHH always seems to get the HKS information first. HKS are introducing a new intercooler and air guide set for the R35 GT-R. The 400mm x 260mm x 65 mm intercoolers (two) are not priced yet, but come in at 1.6 kg (3.5 lbs) lighter than the stock units. One other important part that the intercoolers include are the air guides to the intercooler. The R35 has some very important ducting in the front of the car that channels air though rather than around the important cooling components. If you have ever worked on race cars, you know how important these guides are to efficient operation of radiators, oil coolers, and intercoolers. HKS claims a lower pressure loss than the stock or a competitors intercooler, and that translates into about a 10 horsepower gain. The press release is dated January 25, 2010, so it might be a part that is at least a month or so off.
