not necessary bro. drop in filter suitable for auto transmission - better pickup and acceleration..
does not affect top end power or what so ever.. same as stock filter, also consider drop in.. no difference for top end power be it using normal paper filter or aftermarket filter..
open pod if use on auto transmission will lose abit of low end pickup, but for top end good..
open pod more suited for manual trans as they can play with gear changes..
^ judgement based on my butt dynoÂ
anyways,
all these got something to do with amt of air being sucked in and combust + released from the exhaust..
kinda complicated and difficult to explain.. gotta go google to find out.
similar to the concept of auto using s-flow and manual using straight flow..
something like that, read somewhere bfor but forgotten the reason behind it.

for air filter i recommend simota/works (same thing, just rebrand only) viva drop in filter..
good enough air flow and yet not comprimising filtration power.. no point using filter if it doesnt function to filter the dirty air, might as well buang the whole filter haha! any other brands also can as long as suits your budget and your preference.. dont expect increment of 5-10% horsepower as claimed by most ppl out there though.. all marketing bullsh*t only. if its true, i remove my filter box long ago already, can gain so much power!Â
anyways, its easy to maintain as well, just spray and rinse with water. then u can either let it dry under the sun, or air dry it.
do it which ever way u prefer. for me i clean it every 2-3 months
finally sifoo has spoken. you can refer to this statement about power increment. clearly i was way off track about that
sorry for misunderstanding bro Dreadsic. hehe.
