I guess if the air boxes are different they they would not be technically identical.

They're only different by the shape of the top of the airbox. Both are interchangeable between the IS and GS. This was verified by Joe Z and myself when he installed the "joe z intake" on my old GS and made comparisons with his previous 08 IS350. They're practically identical.

The 2GR has a much better torque curve than the VQ - Nissan had to increase displacement to 3.7L just to match the real world acceleration times of the IS350.

The only advantage is that it revs higher, hence the greater HP rating.

But if you only look at HP numbers, you missed the forest for the trees.

thank god i found this.. its not too late for a question is it? well.. i recently bought an Fsport intake.. and i overlooked the part that it says is350 and i drive a gs350.. so my question is.. will the lower half of the is350 Fsport intake box fit the gs350? like the bolts and the plastic parts that attaches to the bottom for air?

cause i really want to use the top housing of the is350 since i cant return it..

Thats very suprising... I thought the IS would be lighter.... Unless teh IS350 is AWD and teh GS350 RWD

gs350 awd is a beast

Currently need a replacement right/passenger side cylinder head assembly(camshafts, rockers, rocker caps, valves, vvti oil spacers)

1. Can anyone verify that the gs350 share the same cylinder head assembly as the is350?
2. Does awd or rwd matter when it comes to cylinder head?

Greatly appreciate the help in advance.
