its kinda like cold air/short ram. i checked out the AEM site for more info and its like there its not specific on wat exactly it is they just labeled it as a V2. but its great its a cold air but it doesnt leave the engine bayAEM said:V2 systems are developed to produce maximum power. This does not always mean that the V2 will be a long runner configuration. AEM performs extensive R&D for every application (including V2 systems), both with respect to length tuning and inlet temperature testing. We will always manufacture the best performing product, regardless of its configuration and what the industry generally accepts as a “method” for manufacturing performance induction systems. We have manufactured air induction systems for many years, and over that time have developed a comprehensive testing standard that nets consistent results.
