Let us know how you are getting on in a couple of weeks once the car's got used to normal UL.
You may have a problem with the K&N fitting (It may be leaking)or dirty.

The Magnecour leads do definately help as they get a better quality current to the spark plugs.

Mine will be available when the car has gone back - see the lot
