Intake systems

[blacksuperduty]

What is the best air intake system for a 2004 6.0L. My dad has a air raid and it has done a damn good job on his truck and im debating on getting that one, the K&N, or the S&B. Anyone have any input?

well the stock intake system is the best... but if you absolutely had to change it i would go with the S&B or the AFE stage 2 pro guard 7 intake

Stock is the best. If you have to get an aftermarket intake, S&B is the one I would get.

My vote is stock about as good as they come good to 500hp

I agree with the S&B or AFE.

S&B is best bang for the buck hands down, but the OEM flows great, buying a cleanable filter really does pay off in the long run on the 6.0 though.

I heard the stock was the best one up to 500hp. Thanks for the input guys!

I dynoed the Airaid on my first 04 back in 04 and it delivered the claimed power on a brand new stock truck, I have run the Airaid for 180k miles on 2 trucks without any problems. The prefilter sock is good for offroad, but, negates any horsepower gain, so do not run it all of the time.

I had an S&B intake when I put in 175/100's. While we were tuning it, we got 531hp. I had the stocker laying in the bed and for laughs we put it on and made another pull. Not one pony of difference between the two. the S&B was brand new and the stocker had around 4k on it at the time. I sold the S&B and kept the stocker.

Come Christmas time, I will have no choice but to go aftermarket.

A turbo or a tun e that provide more boost and quicker spooling may negate the airflow gain of the filter, also the power gain was NOT at the peak, but at lower engine speeds before full boost was reached. I know that the stock filter system is good to at least 575hp, but the aftermarket systems do have advantages in everyday driving. Quicker spooling, and lower maintainence cost (due to washable filter), more noise is a plus or minus based on personal preference. With a zoodad mod moisture can soak and restrict any paper based filter element, but will pass through any oiled type element. Do not run a K and N filter (they are only 2 layer and are too delicate) on a diesel motor.
