Since moving up from my old 2.8 Z3 to Z4 the only aural pleasure I have had has been provided by my wife (in the form of her Mondeo V6, which sounds georgeous under acceleration)

Just read this how to and have removed just the sponge from the bulkhead end which is literally a 2 min job no tools required. and have been for a blast up the bypass and wow :evil: Car now sounds superb under brisk acceleration and remains quiet cruising at a constant speed. Sponge is safely inside glove box but I don't think I will rush to put it back on!!

As mentioned by others I think there might be an increase in fuel consumption and I seem to have relearned how to double declutch as taught by my old man just to remind me how good it sounds!!!

One happy teddy. :driving: Excellent How too SK93 :thumbsup:

hey guys, just a quick one that has probably been answered before.

does the sound generator come as standard on an 03/53 3.0litre? there is one in the scrappy just down the road from me and il go along and get it.


how much would you expect to pay for a second hand one of a car from a scrappy?

yeah.. it comes in the 03 3.0 litre, cos that's what I've got :D

they're £60 from the dealer brand spanking new, so I'd go and offer £15.. maybe £20.. and at a push, £30... :)

if you look on the right-side of the engine, you'll find this big lump of plastic attached to the back right side.
if you look at my pictures earlier in the howto, you should be able to work out what you're looking for.


EDIT: Here's a guide for what you want :)

I'd grab no7 as well if it's there.

you'd also need the modified air intake pipe that this all connects to.
I cant find it on realOEM at the moment to give you a picture, but you'll know what I'm on about if you have a look see.

i can give you my mobile number if you like, so if you get there and aren't sure, you can give me a bell?

it's part number 5. the left end of part 1 in the original document, will be plugged into this part, at the point where it says "6" on this diagram



in all, you should end up with this lot:

Ok so sound generator fitted today! grabbed it for a tenner, bargain.


i tested the different bits of foam and opted for the small peice still in, i tried without any and OMFG i felt like part of the asda carpark crew!


one question, probably for SK93 :wink: the fixing clip on the bottom doesnt seem to have anything to get hold of on the 2.5i engine or have i just missed a bit theat i should have taken off?

it sounds minging with both removed. i started by taking the little bit out and there wasnt much difference, then when i took all of it out i nearly shat myself. it sounded like something was wrong with the car! :P

so i stuffed the little bit back in and that sounds fine :D
