I'm planning on replacing the spark plugs soon and was interested in replacing the intake tube and cleaning out the maf and intake port in my 2012 350c. I saw this while surfing on ebay (HPS Performance MAF Short Ram Air Intake Pipe Kit RC350 GS350 IS350 V6 13+ RED) and was thinking of getting it if it fits my car since the engine is the same for pretty much all IS 350 models anyways. It didn't say if it was CARB legal but what are your thoughts on this just for the clean look and possibly smoother airflow to the engine. I can just get the FSport silver intake tube though as I'm sure that would fit ok and is CARB legal but the red color just looks better.

If your 350C has the sound generator it should work. If not you will need the non F sport model intake. Also be aware that the pipe is 3.50" ID the stock 350 size is 3.00".
I'm not sure how much it will affect fuel trims being that large. Then again it may not as the MAF is in the airbox top housing.
Be aware that the intake won't fit out the box. You will probably find that one of the couplers, and clamp will be too large.
If so be prepared to buy and extra 3" to 3" coupler, and clamp to make it work.
I experienced this when I bought my 3IS intake for my car.
