Intake elbow

Curious if anyone has any input on how much of a performance gain is had from aftermarket intake elbow. Have the Volant CAI , wondering if its worth another 300 bucks for elbow

I dont know how much of a performance increase there is, but if you look inside the stock one, you will understand why there is an aftermarket one. I want to make my truck breath as well as possible.

You wont see any real performance gains. However it does make it easy for adding water meth nozzles or boost gauges, etc.

x2. You won't see or feel anything performance wise. Aftermarket elbows do add a little bling under the hood, and are convenient for adding mechanical boost gauges, water ports, etc. The real air restriction on a 6.0L is the intake manifold itself.

No point in a larger intake elbow if your stock intake only flows so much..

I really want a ported intake myself, on well on the list it goes.

I bought an accufab elbow and immediately saw an increase of 1 mpg. I only paid $170 or so and I considered it money well spent. The only other mod to my truck at the time was a turbo back exhaust.

The factory piece does have a restriction and it can hurt airflow. It is just like putting a small kink in your garden hose. It doesn't matter if you have another restriction at the end, it still reduces the water coming out of the sprinkler.

No MPG or HP gain, the restriction is in the intake manifold. If your running a 03-04 motor, then you could just put on a '05-07 elbow and get rid of the EGR throttle assembly, or it you have the late '04 motor you could remove the butterfly valve.

Like already mentioned, no gain except for BLING and pre-tapped holes for boost or nozzle's.

The first pic has the EGR throttle plate (butterfly) for the late '04 motors, you can remove the two screws and pull out the plate. You can find this pic in the 2004 6.0 bible. The second pic is the EGR throttle assembly for the '03-early '04's, notice no plate. In '05 they did away with the EGR throttle assembly all together, so if you have a '03-04 you can remove all that hardware and replace with a '05-'07 elbow.
