We'll start by saying..the Alta FMIC is TWICE the size and has 3 times the ambient cooling surface area of the stock intercooler! This all translates to cooler temps and more horsepower! The Alta front mount intercooler features cast aluminum end tanks, with smooth and perfectly contoured internals to create unimpeded airflow and equal distribution of air throughout the intercooler. No sharp corners or multifaceted cores here. The Alta intercooler fills the entire mouth of the bumper and is designed to utilize as much of the ambient air coming through the bumper as possible. Gains of over 10 WHP on a stock car are to be expected!
