I recently bought an 2002 Is300 automatic with this area 51 air intake box. Is this any good? Outdated? Should i look into other air intakes K&N Injen and spectre or does this actually give me anymore or less hp?

 

Its super rare and discontinued piece.
i'd leave it in place and get the filter cleaned if possible.

 

Here are a few pictures of it. I can't seem to find another picture of the one thats in there. Is it a knockoff?

 

 

that's a coolpiece!!!!!
