I remember a respected tuner on here a few years ago saying the standard Volvo Air box and turbo intake design is good for 300bhp without modification - if you've ever peered inside the air box you would say BS because it looks quite awkward and restrictive to airflow but I trust a company that experiments and tests using a rolling road etc.
My car is standard but I did install a K&N panel filter replacement, I noticed a slightly better throttle response afterwards; enough to justify the purchase anyway - and it's washable!
