K&N washable air filter

[Dead Eye]

I'm not sure on that - new paper filter is what £15? K&N can be bought for £35 but for the sake of argument lets say its the retail price of £60

Typically people will replace a paper filter every year as part of a general service. The K&N filter is stated to not need replacing / service for the first 50,000 miles. Now it entirely depends on mileage but even if you do 10,000 miles a year (which as higher than average I think) you will end up buying 5x Paper filters totalling £75

Either way, I think with the K&N option you are quids in for the long run.
