I modded my airbox last week and I must say it it is noticeable....both power & sound. Maybe the power was just as my old air filter was filthy and I put Irridium plugs in at the same time-I dont know. Anyway,heres how I did it... 1:Jack up car & remove nearside rear wheel and inner arch cover. 2:From the top undo this 13mm bolt which is attached to the airbox bracket.  DSC00019.JPG   53.19KB   42 downloads 3:Undo the 4 clips which takes the top of the airbox off and remove top along with filter. 4:Discard filter. 5:Undo jubilee clip which secures airbox pipe to AMM leaving short pipe fitted to airbox. 6:Pull airbox out of securing grommet nearest wheel arch.(Pictured here looking from inside the arch towards the vent)  DSC00020.JPG   44.13KB   42 downloads 7:Remove rest of airbox through arch. 8:Remove plastic pipe (The one which is cracked in the pic) Its cracked as I broke it while removing it.  DSC00017.JPG   44.86KB   43 downloads 9:Remove this pipe from inside the lid.  DSC00018.JPG   50.18KB   39 downloads 10:Refit new filter. 11:Re-assemble.(Remember to fit the bottom of the airbox before attaching the lid as it will NOT go back complete) 12:ENJOY. Whole process should take 40-45 mins. Hope this is of help. Cheers, Danny.

I have it too, as done by a previous owner, and was just yesterday wondering (again) what C's do - whether it's just holes/trumpet or both (or anything else). I love hearing the whistle of the turbo more, but I really loathe that bass tractor/diesel racket on acceleration

I was told NOT to drill holes & also read on the forum somewhere that people advised against it.
Why the holes then and where? Im interested.

11:Re-assemble.(Remember to fit the bottom of the airbox before attaching the lid as it will NOT go back complete)

Yeah, it will. Takes a little bit of wangling but it goes back in ok as a complete unit.

Also, I never have to remove any nuts to get the airbox out? It just pulls free of the push grommets and comes out.

Why wangle & fiddle putting it in in one unit???? Its quicker like I said.
Just undo the nuts to remove which takes 2 minutes!!
I just like things to be done properly I suppose.

[hairy]

Sorry for being dim, is the trumpet supossed to pull out or do I need to cut it?

[siztenboots]

Lid one pulls out

[Ormes]

Both trumpets just pull out but from memory there are retaining clips. You certainly shouldn't need to do any cutting.

[hairy]

Yup, just needed to break the clips! Thanks chaps.

 

Can't wait to try out my extra 1bhp

[scw02102]

It's not the power it's the noise from the turbo u will notice Best free mod out there

[Bumblebee]

I'm probably in the minority with my thoughts but the noise change was too minor for me

With the engine making 200 BHP I doubt there are any gains, but on an engine making 300 BHP I think there are some proper gains due to the increased air demand, perhaps 2 to 4 HP.
