Im thinking of getting a pod filter for my 1zzfe powered 2003 Corolla. All the dudes out here in New Zealand just get a pod filter and have some custom piping done, not really much of this bolt-on stuff. And it turns out cheaper. Which would be a better option, I buy a K&N pod filter and get the workshop to make a custom box and everything for it, or to buy a "bolt-on"? Performance and price advantages would be appreciated.
