u r wrong... alot ppl i know also using drop in filter with CAI
when u rev ur car, the air will be sucked inside.. u can put ur hand there to feel it..
as for scoop, depend on where ur filter located... mostly scoop will be use when the car is carburetor engine (for wira)
since injection filter box is at the driver side of the engine bay, so even if u use scoop also useless...
bro.. ur location for CAI right... will ur dirty get dirtier easily?
i plan to do like urs but my bumper is not stock type
i believe, air scoop type is normally for those 'top mount' intercooler because of its location. there is some different between front mount, top mount, and mine is side mount. err.. for further explanation, you need to google/wiki them out..
my location of CAI is unavoidable. actually is situated right behind my intercooler. the suction is like a VACUUM CLEANER when you rev the engine.. one of the accessories shop 'CLOTH' were sucked in during testing.. luckily my filter was installed, if not, sure the cloth went into my TB.
i check the filter once a week. didnt get very dirty as ppl has mention... probably i only use my car in city drive.. so there is NO insects/leaf got stuck inside.
