Hi, i did a search but it seems the only compary doesn't include the fujita (but has the comptech icebox instead)

i was just wondering which of these were the best bang for buck?

i've heard good things about injen but to be honest the sp1430 is abit too loud for me.. it has a great sound but i think the noise will eventually peeve me off.

the k&n is also great, sounds pretty good but i've heard is not as good a performer.

the fujita seems the cheapest, but is there a reason for this? is it genereally a reputable brand or just is it lacking something?
