cold air intake benefits?

I was wondering what the benefits are with going with an after market cold air intake? I read where H&S posted that as far as horse power and gas mileage your factory filter is just as good and maybe better. has anyone noticed lower egt with aftermarket intake? BTW I have MINI MAX and 5" flopro dp back no muffler.

I installed an AIRAID system and I am very happy. Throttle response is more crisp. When you remove the stock assembly, you will see that it has restrictions. Any restriction is a loss in power. Plus you also need a smooth flow of air. The factory air box is not the best design for flowing air. I also feel the factory air filter is VERY restricted.

All said and done, how could a cold air kit not improve power? If they are making it, people are buying - it must be working. If it was not working, people would be returning them and the companies would be closing there doors.

seems like these could certainly be an advantage, if the tuner was tuned to take advantage of it, otherwise it may cause you to lose power.

H&S is not, I specifically asked this question. They are tuned for a stock air intake.

Thanks for the comment. I was just wondering because I had a AFE stg 2 on my 6.4 and it made a huge differance and i loved it then I ordered one for my 6.7 (which was ordered over a week age and they still haven't shipped it) and after reading what people was saying I was wondering if it was worth it. but I do miss hearing that turbo under the hood

I hope you get it in soon. I have a S&B on the way and can't wait to get it on. In all honesty, I am not as much as concerned as the power gains as much as I am with hearing the turbo breathe better! Is that weird? I think I am addicted to that sound. I guess the other benefit is the power increase!

H&S says the stock filter setup is not restrictive at all and does a good job. They also state that their 'truck' runs the stock filter and all tunes are done with the stock filter.

IMHO you are wasting your money if the tune isn't adjusted for what you change.

By the amount of black smoke (unused fuel) that was coming out of my exhaust while using the stock air filter I can tell you there is some benefit to a CAI. My truck has significantly less smoke and much better throttle response now with a S&B intake with the cover removed.

Will the truck run good with the stock air filter? Yes.

Will the truck run better with a good CAI? Probably so.

Required? No. Beneficial? I say yes.


H&S tuned, on HOT all the time.

I remember when I got my intake on I thought it lost power and almost put the stock one back on.
