How can Nissan sell a new single model AWD TT GT-R for $95K when a BMW 330 TT (based on a common as muck beemer) is $110K?
Even the old model that was based on a lower spec rwd version was ~$145K here as a private import with some kays on it, and this one is an entirely stand alone model.
The facts don't add up for me.
AutoSalon mag tested all the popular pod filters a while back, and the best performer was a cheapo 3T Racing paper filter- can't remember the exact name. I'm sure someone will correct me.
But, yes: paper > foam
Any modification that changes the emissions away from OEM specs is illegal without being tested and certified for the particular car- So an aftermarket factory location panel filter from K&N would technically be defectable.
