Can't beat the OEM dry filter. You have change a little more frequently. But they are cheap and no real power difference in the K&N. Many tests prove this. The only real benifit is a little more sound which gives the driver a bigger smile and helps with believing your car gained power. And if there is any more power at all, it would make no difference in a race. Go OEM no MAF problems. Jags engineers got it right. The only way I would pay a premium for a filter is if AFE or some other company came out with a dry filter for our cars.
