For me, what I heard is:

Open Pod Filter provide more horse than Drop-In Filter but FC becomes higher than normal, Drop-in filter provide less horse power but better FC...

Is this true? Anyone plz correct me...

Open Pod Provide 13-14BHP....how about Drop-IN?

For drop in filter you do not need any extra modification, just drop it in like your OEM filter and you are ready to go.

As for open pod a.k.a. mushroom type filter, a lot of things need to be taken into consideration to extract the full potential.
You need to install a proper heat shield to shield the filter from the heat generated by the engine, if not the air filter cannot be run at its maximum capacity.

Final consideration is that how much you willing to spend and what is the gain in horse powers you looking at

OPen pod provide higher air flow to engine, while drop in is lesser.
but the air flow noise will be loud if using open pod......

for performance increase, open pod is better choice
but you said 13-14BHP increase, i think is too difficult........

where u get the figure adding 13~14BHP?
i think it add barely 5hp

13-14 hp is too much man ... i dun think that is possible...

nope.... drop in is around 2- 4 while open port should be 5 - 8... 5 - 8 also depends how u set up ur open port.... if u suck more heat rather den cold air which is also useless...

Some Open Pod Air filter will harm your engine. While I heard some said that, K&N Drop In Air Filter also can work well as those open pod air filter. Open pod air filter will cause FC increase a little bit but more power. I wanna change to open pod air filter, but the SC don't give me change cause will void the warranty. Cause those open pod air filter sucking more air that stock drop in so it will harm the engine.

13-14hp? if you are running a high displacement or turbocharged vehicle, you could see those gains. but on normal engines, very very unlikely

if its a turbo, then 13-14HP is logical
For NA, u get 5-6HP also happy adi

once you got open pod....you mod will be go on to get full potential of the open pod.

it's like PC, if your motherboard is cacat but you got super cun display card, the display card can't performed at full potential. So you must upgrade motherboard, then later need to add Ram then bla bla bla...the list goes on...

what are u trying to imply here

"The quest for more power nvr ends"... That's a motto i bring since days of overclocking pc all the way to now with playing cars pulak

hahaha.... actually both is the same lar... both using the same filter element... jz that how it mounts and so on...

open-pod
ppl say it FREES UP (not give) more horses because at high revs, the air flowing in is not restricted by the shape of ur airbox.... thus, u'll get smoother revs at high revs...
but the disadvantage of it is, it is exposed to the hot temperature in ur engine bay.... this can be solved by using heatshield and cold air intake...

drop-in
direct replacement into ur airbox... thus, all the factory setup cold air intakes and snorkle can reuse again.... good, no need headache go do heatshield and cold air intake adi.... but at high revs, its kinda restrictive due to the limitation of airflow inside ur airbox....

applications...
if u want to go further in car modifications.... if ur driving style is mostly at moderate n high speed... try go for open-pod....

if u jz wan abit increase in horsepower and ur driving style is around town area with lotsa low speeds and stop-go, use drop-in....

ok??...

ok boss

what about cleaning the filters? some are reusable. but how many cycle can they last?

open pod, u try getting stuck in KL jams on a sunny day and see


or try going thru flash flood areas

nothing wrong with that.. ii get stuck in jam everday well, nothing out of the odinary ...
eh,kacang, my car height higher then yours, so no problem

your 4WD ler....

we talking about cars


anyway i am using drop-in, gave up open pod idea.....
too much hassle for such a small gain

Usually I prefer Open Pod, but it gives higher FC....how high? Do u know?

c this....
Yeah i know this...how much does it cost for heat shield n cold air intake?

K&N can work like Open Pod? sure or not? I wanna try leh...



I know, so open pod then must change the whole extractor, exshaut etc mah..





Mmmm...icic, I guess i take drop in then....coz dun REV, just want low end power more...





Wat r u trying to tell?

open pod will not give u that much of a gain la...
realistically a gain of 6-8HP is achievable... anything more and you are lucky...

what i mean is that open pod is almost useless in a jam on a sunny afternoon, u lose power and consume more fuel


and when flash flood area, if u have a CAI and u did not secure the intake correctly, water will masuk all the way until your engine..

i know of one case where that fella neo engine koyak because masuk water.....

How much u willing to spend.... u can do the whole open port with heat shield cheap or expensive.. as cheap as 500 bucks also enough.... as much as RM1k and above also got.. speedworks charging around 700 for knn open pod and they heatshield...
