I just installed the aFe throttle body spacer by itself with the stock intake and stock exhaust. I noticed a bit more response out of the throttle and no whistling like everyone complains about... Can't wait to get the aFe si intake installed followed by the Dynomax exhaust!!!

 

Instead of intake try putting headers on with exhuast tht will wake it up then put a drop in filter

 

I beg to differ. I have a Lotus and the Fujita cold air intake has "claimed" to give an 8 hp boost. Stage II track exhaust...3 hp. If there is one thing that I have learned is that there's not a DAMN one of these that ever puts out what it claims. In the racing world, we call this the "butt dyno". It sounds tougher...sounds faster...but it's really not. I have the Airaid, Magnaflow, RR headers, Superchips and swapped to 5.13 gears. Not any faster. Distribution of torque...sure. Sound cooler? Yep! More HP? Naw...
