well from my personal experience open port for an auto car is no good
i experienced loss of power in my putra
the oni reason i put it in is for the nice sound
i cant comment bout drop in coz personally never tried(still on open port) heheh
but from what i heard form my buddies its better than open port for auto cars
hope that helps :top:

try using KnN drop in airfilter...i've been using it since 3 years ago...

but a few mods if did...cut bigger holes in the airbox....suction sound still there...not sure about FC n power loss tho...never used open pod b4...here very dusty. dun dare use.

normally a stage 1 tuneup done in this this step
1. Exhaust
2. Intake
3. Piggyback management

most of the time I've heard that by installing open pod alone will result in the powerband shifted a bit higher in the rpm range... that's why IMHO is what mr kumar is experiencing... I've experiencing the same thing when I used k&n open pod with hotbits intake kit with my old engine... the power curve shifted a few hundreds rpm higher and oso experiencing a bit drop in torque level as well...

so... if you really wants to get the most of it, better do the 3 mods i've mentioned above... but bear in mind, at most ppl will get with these 'bolt-on' upgrade is around 5%-7% only

yeap yeap loss of torque so the pick up is not there anymore and for auto pick up is hard to find compared to a manual thats why i say for performance open port not so good for auto
ohh and i didnt know if we live in surrounding with dirty air we shoudlnt use open port??
anyone care to explain why please?

read it somewhere before...being an open pod filter...of coz it offer better airflow...but it tends to suck hot air (which we dont want) from within the engine bay if installed without a proper CAI or heat insulation...my opinion...better stick to stock/uprated drop in...happy motoring

Kumar22mostwanted: you can offset the loss of torque with a good exhaust system and a well-tuned piggyback management ecu... there's nothing wrong with open pod...provided it came from a reputable manufacturer such as k&n, apexi, hks etc... I like k&n better because i can wash it

bera: second ur opinion.... need a good CAI or insulation... I'm using k&n on my turbo engine since the job for cooling the air already taken care of by the intercooler hehe

owh please dont listen to my advice... :) it just common sense bro...hot intake air equals to drop in engine performance...a small percentage only...you might not even notice it at all...don't just go throw away and waste your air filter just like that...

for campro engine if u using open port then it give slightly trouble in city driving. But highway good ah, last time try put open port in persona auto run 190km/h easily at the highway. But remember the top speed will drop.

wah,looks like have alot of negative feedback on open port for auto,hmm...by the way,currently i am using works engineering drop in air filter with cai installed frm my persona spot light hole straight up and connect to the air filter box,i just thought maybe my car can suck in faster air using open port thus improve the pick up more better,i only lack of a heat shield with my current set up becos right in front of the air filter box is a fan...the heat is the only problem,does anyone know where i can buy metal plate which is flexible and can be bend?hardware shop got sell?since open port not so recomended,i plan to diy my own head shield to block the hot air from the fan to the air filter box,maybe i'll attach a pic for you all to see then u can give me some opinion on what i should do.

hehe no lah bro ive got similar advice from several people regarding this matter so no worries :top:

your setup is nice oredy... but if you want to install open pod, its wiser to do a heatshield... you can buy the aluminium sheets at local hardware store, but u need to measure...

try browsing the DIY section, I think lotsa ppl done the heatshield DIY...one of the example are here

wow,very nice and neatly done....i realise if install open port will free up more space in the engine bay and the heat shield can be easily done and adjust,but like my case if i remain the filter box and diy a heat shield i really need to think how to put as the space is limited there,i think i'll upload the picture maybe by tonight for u guys to have a look and give some suggestion,the guy also manage to buy a color metal plate,nice nice....hehe

Just wrap your box with Superlon or Insuflex.
