I am now on my second S80, this one is a 2005, Se D5 Auto. Having succesfully fitted an after market stereo, to replace the never working old HU-850, is it just mine or when you go over a pothole, is it like someone taking a sledgehammer to the spine or is it just me? I am sure my V70 and XC70 weren't as bad as this? Secondly, has anyone fitted a aftermarket cone air filter instead of the box? My airbox has warped and now doesnt seal shut, making me sound somewhat chavvy with a dodgy airintake, all i need now is some 'pops and bangs'. I just thought fitting a cone would be cheaper than the price of £139 for a replacement box.

Cheers in advance
