This explanation came from the AEM website...
"The AEM V2 utilizes a dual chamber (using two different diameters and lengths of piping) that creates multiple frequency sound waves to produce the largest area under the curve of any intake system on the market. These sound waves help charge the cylinders with more air throughout the entire rpm range and are what enables the V2 to outperform even our own Cold Air systems.
We have found that inlet length plays a vital role in the power production of V2 systems and not all V2 induction systems relocate the filter outside of the engine compartment. In these cases, we performed extensive temperature testing to locate the filter in the coolest area of the engine compartment to achieve the lowest inlet temperatures possible."
I think that it uses that relocation of the filter to the coldest area of the engine compartment like a cai does but then the whole sound waves thing supposedly is the advantage over it. It really didn't explain why the sound waves would create more power and i don't really understand it but that's just me. They have a link on the website where it explains how the V2 intake works but the link doesn't work =\
AEM claims that the SRI produces between i think 9-11 more hp...
and how does AEM claim the SRI puts out more hp? are you saying its 9-11 more hp more than the V2? i thought they were saying that the SRI would be a more affordable alternative to the CAI and V2 would be pretty much the top of the line. that's what i got out of AEM anywayz
