no need, especially for a 5sfe....a standard 13 dollar filter will do just fine, if u blow through it u will realize how little resistance ther really is, just keep up with the maint. and ull be more than ok performance wise
*a clear one would be cool but no need, im not sure wer its located on ur 5sfe bay but with my 3vz-fe u can barely see the thing...
If it was out in the open what would be really

is getting a clear one and puttin a couple tiny neon bulbs near it, and accent ur engine bay

.....i might actually think about that one now, thatd be sweet since many of my hoses throughout the car are now clear
