The purpose of the intercooler is to cool intake air in the car engine. Cool air takes up less space than hot air, and that leaves more room for fuel in the mixture of air and fuel which is combusted in the cylinder. This increases engine effect without increasing cylinder volume, thus offering advantages such as lower fuel consumption, better economy and less pollution. Nissens' range of intercoolers covers more than 75% of the aftermarket for passenger cars and trucks, and all intercoolers have been designed and constructed to comply with Nissens' strict quality demands.
