You want the 3" version. Not exactly a "direct" fit...you still need a MAF translator and maybe some couplers, pipes or a different air filter, depending on where you want to mount it.

Personally, I'd get a 3" curved hard intake pipe and a 3" K&N filter and maybe a blow-through setup to go with it instead of modifying the stock aircan to fit and using the stock accordion hose.

3"flows plenty with a dejon upperIC pipe designed for accepting the MAF in ablow thru position. Nice!

3 inch for sure, and just make your own custom three inch pipe, then you can get it powder coated or plated or what ever you want.
