I ve had a 57i cone for 2 and a half years/20000 miles and also have had no issues at all, Its definately louder than standard and grunts until the turbo spools then it becomes super whoosy. With the 007p DV a nice blow off when you lift or change. Has become twice as loud since the map too. However i had read post after post and have decided to give the panel filter a go. I have a green cotton and a box to smooth just the work to do
The oil ruining your MAF is a red herring.
I have run a K&N for the last two years and 25K miles. Tonight, I took it out to have a look at the MAF and there is no sign of oil and the car _still_ runs a treat.
IMHO, if you over-oil, when cleaning it, you may suffer a small period of iffy behaviour, but in general don't worry about it.
Think about it, if it really was a problem, K&N would have gone out of business a long time ago....
There is plenty of info on this site about which one to go for.
i agree with you mate,i had mine(57i) for a year and did 20000 miles with no probs.i posted a video of it on youtube in tunnels!? have a look/hear!......

Hiya mate did you have a DV? If so which one was it and did you reverse it? I only ask as people have said in this forum if you reverse them you get a chirpy sound and as that sounds completely different to mine i was wondering if this is why.
