Do I really need a CAI?

[tony97gt]

I was considering on buying a CAI for my 2008. After speaking with a buddy who was had his 2005 for quite some time, he told me I really don't need a CAI. He said the stock filter is good up to 800hp and filters well. He also said that the CAI is less filtering which has the potential for more dirt to enter the engine. My truck is stock right now as far as mods to the engine go, but if my dealer is mod friendly I plan on adding a dpf delete, removing the cats, and adding an exhaust from there. Not looking to get into the down pipe or anything like that, and I will obviously be adding a tuner. Is the CAI necessary or should I save the $$?

You answered your own question. Stock will flow and filter well

for my understanding a stock one is only good to 500hp and if you have a spartan or h&s tuner you will go over that

I agree with this. On the higher horsepower tunes you will suck in the filter minder meaning the truck isnt getting enough airflow.

Just get one when you do a tune and DPF delete. No need before that.

exactly..........

if you are tuned on anything higher than the 250 tune you are going to need it. I tuned to 300 when I first got my tuner and every time I got onto the freeway my "check air filter" light turned on.

Every time...

I just put on a afe stage II spartan tuner and the afe cat\dpf delete and man new truck more mpg run the 300 tune with sense haha.

i got one after a tuner and exhaust. getting another mile better per gallon. throttle response even better. no buying 75 dollar factory filters.

This.

It may help slightly in stock form, but becomes necessary when tuned.
