I would imagine every service, so 2 years / 18k or whatever the schedule is.

Any one in the uk fitted or researched a cone filter and heat shield??
Dont know about in the UK, but here is a side by side test of performance filters and induction / cold air filters. Done in Oz right enough, but all compared against normal paper filters:

Based on their findings, I wouldn't waste my time on anything other than a normal filter. Ok, a performance panel doesn't need to be changed, but as they are only getting changed every service, you would need to keep the car 8 years or something to get your money back.
