a New induction mod question

Hi everyone,

so after reading a whole bunch of posts on induction mod etc i have come up with the following and would like some advice.

i have a k&N 57i kit (i know about the maf in advance thanks!)
but
I am thinking of mounting the cone filter inside the original airbox with some samco pipe or similar to replace the current filter to take advantage of the current air intake (as we all know the filter in the engine bay ..heat sink..is kinda daft) and water protection. then i'm thinking get the v6 intake pipe to get more air flowing in there. . . i have a few questions.
1) has anyone done this, does it work and does this sound like a good idea?
2) when the cone filter is in the original air filter box does it need to be 'sealed' like the original to maintain a good air 'vaccum'? or can it just hang inside it?
3) the 57 k&n i have IS oiled so.. being aware of a possibility of maf issues can anyone suggest a way i can remove any excess oil before i mount as a just in case thing.

i guess i am interested in the increased noise and effect of the K&N cone filter but i want to take full advantage of the current & modable airflow setup.

any help, suggestions or what not would be great!!!!!!!
thanks in advance

It should be fine just to hang inside it, this sounds like a very good idea

Although sealing it inside the airbox would be better I think, to stop it drawing in warm air from above.

Take your MAF out and let the car run for a bit without it. Rev it up and what not, let it idle for ten mins, only then re-fit the MAF. You should get a killer induction noise with a K&N in an enclosed space

thanks!... do you mean i remove maf, insert the k&n into airfeed and run the car with that on to suck out the oil kind of thing?

Yeah, don't just unplug the MAF, it needs to be totally removed. You could just attach the K&N straight onto the throttle body if the pipe is the right diameter. Basically as long as air is flowing through the K&N, into the engine, 10 mins of idling and some revving should do it, it'll definitely be free of excess oil then.

But while you're doing it, I think you should unplug the MAF from the wire it attaches to, otherwise the ECU will detect that there is a MAF present but no airflow over it, which might make the ECU go a bit loopy.
