Review on AFe Power Silver 46 32005 Throttle by Joe Gilmartin

Added a Fe TB spacer after installing the K&N cold air intake. I haven't noticed much in the horsepower and torque department, but then again I don't test it and run it after every mod. Under load there's a faint whoosh around 2500 rpm at certain times, but if you're driving with the radio on you won't hear it. The only thing I noticed is that I got a few extra pulses (0.4 or so) in the MPG which, if you do the math, will help over time. It can always be related to driving differently etc. but I'll give you the benefit of the doubt.
