im really not sure now dude. im well confused. air filters only increase it like 1 or 2 bhp and make a noise. if you want a noise put a backbox on.
the best bet if you REALLY want an air filter is to replace the original and sit it on top of the carberator. a mate of mine has that done i think. does this help u

A little. i want to install it properly as balinju said. however if water gets sucked in its gonna cause problems when it rains (unless you put a fine mesh over it to stop water going through i think). im probably gonna consider fitting it like yours i think if it does anything.

Is that picture of the engine bay of your car MPPOLO?? if yes, have you noticed a change in the induction note of your car at all?? or does your engine sound normal?? i know it wont make any changes to bhp connecting this way.

no its not mine. i found the pic on the net. but yes it does make a difference to the noise, i know someone who has got one and it sounds a lot deeper and aggresive. i want my car to sound like that but i think it is too much hassel with an air filter with all the problems it may cause thats why im sticking with a back box

U Can download a induction kit installation guide from K&N. I think im going to install this K&N style and see how it goes. The only problem ive really heard is providing the cool air. As if water comes in, it can get caught in the filter. Are there any other known problems??

However im going to modify this by using a teastrainer mesh net on both ends so that nothing but cool air is passed on to the filter as its quite fine. Im quite sure this will work without any problems. Will post pictures up once done but im just waiting for my breather now. Once i got this, i can then install it.

cheers mppolo and balinju for your help

sorry for taking a whole day to answer, I was away

Installing the filter as posted in that picture is not bad, it seems quite good actually, the problem is how to get cold air to it. Cars only need cold air, that pipe from the exhaust is required for starting the car and bring it to optimal temperatures on very cold days. Look closely at the T where there are the 3 pipes connected, you will notice that in the piece that connects the pipe coming from the exhaust manifold, it has sort of like a valve. In the place where I live, temperature never falls below 0, so omitting that pipe will actually not result in anything bad. Remember that once you achieved the optimal temperatues, the colder the air you get to your engine, the better.

Fitting 2 filters after each other is like wanting to decrease the weight of the car but you put a 2ton concrete block in the boot
The idea of a cone filter is that it is less restrictive than a normal filter, so air flows quicker than through a normal filter, hence the aggesive noise. If you install two filters, than its like you did nothing!!

i want to leave that t shaped thing intact. i want to keep all the pipes connected as it is, and will just rest the pipe taken off from the original airbox near the new air filter. Do u reckon this will be okay mate? As i dont want 2 really remove the exhaust manifold.. but should this do as cold air to air filter or will it need something more direct like your connection?

It should be ok, but you will get more hot air from the engine bay in my opinion because the filter will not be enclosed like the original one. It should be ok but it will mearly increase 0.5bhp I think. What you will notice is a better responce. When I installed mine, responce improved a lot and I gained some power at high revs

okay, i think im gonna have to do some trials of both. but i think your right. so is the plastic thing connected to the wing supposed to draw in cold air? i dunno, my main thing is to keep everything as original as possible , as i heard air filtering and intake stuff is very important and could damage an engine if not proper. I dont want to do this can this happen lol

without filter yes you can damage the engine, but I cannot see how you can damage an engine with a filter on if not installed very very well. just make sure that it is sealed properly, and nothing bad will happen

The plastic thing is there so that the engine draws air from the wing rather than the engine bay, it may not be very cold, but colder than the air found in the engine bay

okay cool. its just cos mines a damn universal air filter, which i have heard is meant 2 be good. 1 more quick question then im gonna fit it and see what happens over the weekend.

1. does a filter need to be oiled or greased...no instructions came wid it guess thats why it was cheap and cheerful!

cheers geez

Quick answer, NO it should be fine to use it as it is.

Hi mate, one more thing. I want to get a pipe like yours to connect between the bumper and near the air filter. Any idea what is the best type of pipe i would ask for and what length of it would it need to be? most autoshops are offering me a steel looking pipe which i dont like, im after the plastic or black coted 1s. But i dont want to get the wrong size as they r a bit costly for a pipe cheers

Steel piping is the best, but you need to get a custom made one plus it is quite expensive, something like a flexible tube is pretty cheap, is black, and can be stretched, shortened, bend it ..... then just tie it with some tie rips and you are done. Shouldn't be that expensive. Beware where to put it, because of the rain!

Well i tried to fit my induction kit. But no luck. The filter is too big to close the door. Therefore i am thinking to mount the air filter on a pipe near the headlight. this will require the filter to be put on a pipe, with one end on the trottle body and the other on the filter. However instead of using a pipe, do you think it would be okay to leave the airbox, but remove the air filter inside. Leave the breather pipe and the other large pipe at the top connected. But on the other end of this large pipe, i would mount the air filter. So that the air is filtered in by the new air filter, travels into the original air box without filter and enters the throttle body.

Also checking my breather, it can be seen that it has been coughing up some oil. Is this normal?? cos there is some residue of oil hanging around in the original airbox connector for the breather.

the setup you are thinking of is good in my opinion. Regards the oil, it is normal to find some little residues of oil near the oil breather exit, but I hope that your airbox is not flooded with oil.
