When I do my 'mini service' I am going to replacing the air filter. Does the K&N Air filter have any benefits of the stock one? Thanks...
K&N Air Filter - £35
Iridium Spark Plug - £7
Oil Filter - £5.50
Castrol Power 1 Racing Oil (4L) - £36.50
(Approx cost of £80-£90 for service).
Am I missing anything worth doing?
Also, when should I do this - currently only at 1100 miles.
