Ok so hope u guys dont get pissed LOL but this noob is tryin to figure out what is meant by the foam, that can be removed for the intake..... I pulled out the air filter and coudlnt find the foam ? would someone be able to show me a link or am i that noob lol A pic would be great

Intake is my next step... But if this works i would love to get a lil more sound till then thank you
NOOB

 

I have no idea either...If I find anything, I'll post it here.

 

Help anyone some one on here said that the foam removal was apart of my volvo too to get more sound but im still confused help please

 

Sorry but haven't seen that nor know what that would do to help.

A cone filter will give more turbo noise and you could hear the bypass valve when you let off the gas BUT then you will suck air and it will not be efficient.

 

You know where i can find the intake tube/pipe for my 05 s40 t5 i got a nice filter on the way from a friend who makes customs so i will try it out and if its good spread the word but i need the pipe and dont wanna have to spend alot of money on it for now ...

 

Only thing like this I've ever heard of would be an intake resonator, and those are only found on Japanese cars. Once removed they give a deeper throttle and idle sound.

 

Well idk what ppl r talkin about this foam thing it doesn not exsist on the new 05 + or 2nd gen... What i did notice was that there is a piece of plastic right behind the grille on the left side .... If u remove it u will get some more sound and it sounds great but my worry is that it will allow more dirt into the filter and clog it up but sound wise it is great... Ill make a write up and post with video ..

 

Foam does not exist on the newer generations.

The foam is under the air filter element and on the lid (I think) removing this will make a whoosh sound when you let off the throttle, although tech is right a cone filter will do more. Plus it looks freakin' sweet under the hood! I will look when I get home tonight at my old airbox and see where the foam is.

There are also numerous topics about this on s40concepts.net (check it out older S40 guys)

 

thanks for the info on this, this is the first I've heard and now i want to remove it right away to see if the sound is better...

 

I removed all my foam, the upper and lower and haven't noticed any differance at all in sound.

 

Go WOT and then release your foot from the accel. pedal. You will hear a whoosh sound. Sort of a pshhhhh. Sounds sweet.

You can get even better sound with a cone filter: I suggest a heat shield with it. Someone on here made a heat shield out of cardboard! LOL!! Does nothing!

 

Cone filter could u suggest some ?

A few different choices would be nice .....

My custom filter was too large lol
