Keith is correct, I can confirm that above about aFe / TRD ^
A little tech info for you guys...
Funny thing those AFM (air flow meters)... sometimes a filter can improve performance on those cars vs. no filter. You must be asking- How?
There is a difference: Eliminating restriction of the filter vs. no filter isn't complete / relevant data... We must look further.
On some cars, those with AFM especially close to the filter element, removing the filter, changing the way the air moves over the sensor element can cause turbulence over the sensor- and cause problems when it sends this erroneous data to the ECU.
Perrin Jeff posted up some very nice information on this phenomenon in their Intake Thread, thats a good read for those not frillier with intakes on late model cars.
Now I do not know for a fact that this happens on the FT86, perhaps only the few that have back-to-back dyno'ed the cars and data logged do... Jeff might be able to pop in and tell us that this phenomenon was observed, or that it was in fact not relevant in this case and the stock OE filter element was just that good.
Perrin are also using a Dynopack dyno (One of my favorites for this type of work). These are extremely accurate and would be very good to show some gains, even if in the 3-5 WHP variety as they are very sensitive if they are used under closely controlled conditions.
