I have a Honda accord 2,2 turbo diesel 59 plate will a sports air filter give me any more power

 

I would add a flux capacitor -- I hear those can increase power by up to 1.8 jiggawatts

 

Not sure on the diesels....I'm in the US so we don't get those....There are some other members o here from the UK and other places that might be able to give you more insight....Good luck and post back so we know and might be able to help the next person.
