I currently own an 08 is350 and was looking into intakes but wasnt sure which is the best price for performance and sound.

what do you guys think?

 

cut a hole in your airbox just like the f sport one and you'll get the sound. If you want some engine bay bling, maybe get the f sport tube which is like polished aluminum? or the rr racing carbon fibre one. Just don't get those takeda short ram intakes with the exposed filter

 

The downside about the hole and F-Sport are higher intake temps from no fresh air at grill entree.
And if you get some ducting for fresh air, now you defeated your purpose. Well if sound was your mission!
