I got a K&N, I was going to drop some loot on something more expensive but our cars are factory tuned almost to the max so there is very little you can do to increase performance, short of Turbo/SC. If you get an intake, headers, full exhaust, this helps but it's quite a large investment for small performance gains. Plus, our stock intake systems are pretty effecient as is.
