K&N or AFE?

or if there is another that would be better I am up for suggestions

The less expensive of the two. Why? Because in most cases the performance increase obtain by adding a CA l is roughly around 0.000000002%. If this is your only performance mod, do not waste money going too fancy.

There r usually VERY minimal gains associated with adding cold air intakes on many vehicles, including the Scion models. On average, intakes will give u 2-3 more hp. That is negligible under most driving conditions.

Some people report seeing a slight increase in MPG, & better throttle response. When we were running an Injen CA l on our Scion tC, we ''thought'' there was a gain, but it was probably psychological :p

Injen has dyno sheets of their intakes, but l would say go with looks & sound more than anything else. Preferably something not too flashy if the police like to pop hoods in ur area!
