I was skeptical about the design as well. It is super rigid and not even close to a dryer vent material. The interior of it is corrugated as well, and honestly, I don’t see or feel any difference of any restriction of air flow or power. I am very happy with it. When I cut 2 inches off the tapered part of the factory horn, that restriction was more worrisome to the airflow rather than the corrugated interior of this memory flex hose. The ridges inside are minimal and I personally believe they’re not big enough to give any back flow or negative effects.

 

Hey man, if it works well and you like it, then it's good enough!

 

Are the outlets of the airbox much bigger than for the 5.8?

 

Might as well cut the horns off the intake hose also. At one time it was a popular thing to do. I still think it helps air flow. I know there are lots of pro and con opinions. Sandy

 

I have cut the horns the intake and I did notice a difference, not much though. And the new setup is nice. I’m liking it a lot. Just waiting on the other pieces to come in so that I can go all the way up to the throttle body with it. It hasnt weakened or sucked down from air flow and I am rather pleased with it. I would for sure recommend it for others, plus I think it looks better than the normal rubber hoses.

 

Corrugated air ducting has terrible air flow compared to the smooth rubber factory stuff. Inside of the corrugation the air is turbulent and bouncing resulting in a higher then stock air pressure. This can result in a efficiency loss which can lead to lower HP and lower MPG.

 

Yea.... that’s kinda where I was going with my question.

 

I did research and they said the same thing about the corrugated. I could understand that, but I honestly don’t notice much of a difference at all. Although, I haven’t actually had it tested to machines for the actual horsepower change, it is not noticeable. From the hose that I had on there that was swelled up, it is an improvement. Have you had any chance to try out the corrugated ducting? Or is it just something that you read up on? And please don’t take those questions as an argument, just asking.

 

pic looks like you only did one side, may seem sluggish, off idle/part throttle(leave from stop), once you get the other side on, if you cant pull some of the accordion look out, but not stretched as tight as dicks hat band(lol) you can have turbulence, until you get enough speed to get the air to take path of least resistance which is in the center of the tubes, if you did the air horns when you fixed your swelled tube may have been why you didnt see/notice change

 

I am going to go all the way up to the throttle body. I do like your suggestion of taking all of the accordion part out so that the air flow has as the least amount of resistance. I have cut the horns and that initially gave me a small boost. It for sure isn’t sluggish. Recently I have put in a new timing chain, timing chain cover, harmonic balancer, water pump and have set the timing. It runs amazing (other than a small leak at the oil pan). What do you think if I added a K&N air intake? Would you think that it would balance out the resistance part of it since you’re supposed to get more air flow with an updated intake?

 

my opinion, you have the best ram air, air intake you can get, right in front coming through grill, you will get mixed opinions, but $200-300 to loose hp because its getting hot underhood air, I wrapped my hoses your having to replace, all the way to throttlebody, with a aluminum turbo blanket, cut in half to help keep heat soak out. Wix and(dare I say) so forgive me, ACDELCO have the best flowing/filtering replacement,

 

Yeah...Just stay AWAY from so called "Cold Air Intakes". They are a complete WASTE of money.

People always argue this....BUT if you feel that sucking in HOT "INTAKE" AIR is proving to create more power, then I won't try to persuade you.
Torqu'ta 5 8 is right. Just stick to Ford's BEST CAI.

 

On the I6 intakes, are y'all cutting the half elbow off at the end? Seems like it would take away from any ram effect. My truck is missing the little flappers on the sides of the core supports.

 

CamoF-250,I dont think I'm answering your question ? but just for reference they are cutting the horns (460) that the 2 hoses connect the throttlebody to the air filter housing

cur horns off and re-attach hoses

 

No I was talking about opening the snorkel from the core support to air box to be more forward facing.
