These are the 3 I found that are compatible with our cars. Another follow up question, does it need to be cleaned? A friend of mine has an intake and he told me he cleans his periodically.

 

Injen sounds good but any intake will add some sound to the car. I believe all of them have some maintenance involved, Injen is a dry clean meaning unmount, shake off loose dirt and debris and use a vacuum on the outside part of the filter and then mount it back.

K&N uses a recharge kit that wets the filter and then oil it after it dries fully.

 

Takeda is the best I would say.

Dry filter is easiest to maintain.

They will all sound similar, it is just a pipe and cone filter. Any air filter will need to be cleaned periodically. Of the 3, I would go with AEM or Takeda. Those two retain the factory cool air inlet, are dry filters and have a heat shield to minimize drawing in hot air from the engine bay. They all add sound and not much more though.

 

best sounding intake?

screw it, just take off the intake airbox assembly all together and call it a day.
