They all look the same around the $20 range, never heard of Bomz or X3 racing or GT Racers (looks like a HKS Clone) before but for the price, i’m just looking to get my stock intake out of a box and these 3" ones look like the way to go, what do you guys think?

Edit: well, thinking about it and it would probley be better to spend $40 and go with something like AEM or K&N.
