I paid over $400 for the Aefis AE Carbon CAI a couple years ago for 2009 R/T. Now that I have a SRT8 392,I haven need for it. The manufacturer claimed a 22 hp increase - I never dyno'd it to determine. If someone is interested, I'd welcome your offer. ihad it on my car for about a year. It has a lifetime filter, and I can include the filter cleaner kit also.
