Hey guys. I wanted to let all you 4.6L owners know, before you go out and buy an intake, to remove the silencer from your OEM intake tube. I just got home from the test drive after I completed the mod and am very impressed to say the least. Throttle response is improved, and I'm feeling more torque down low. WOT onto the freeway from a stop was probably the best improvement of all of them.
Keep in mind I have 3 inch IMCO exhaust so this probably enhances the effects (more air in, more air out). Note that getting the tube out isn't easy! I spent an hour with pliers and a screwdriver prying and pulling before I finally forced it out. It's definitely worth the trouble though. I'm surprised and impressed by the effectiveness of this modification. I plan to add a K&N drop in filter to the system for even better results. Many thanks to ASINATRA for this great mod. You the man!

 

glad you like it, hit me up with your AIM again, sometime i will be p&p + gasket matching a TB and Plunum and i will let you know how that goes

 

That thing is a mother to get out but it is suprising the difference it makes throttle responce is great and i haved the open filter using a k&n and i love it.

 

Can this be done on the 5.4?

 

^^^^ What he said.

And, could I get a little more detail about where the silencer is located on the 4.6L?

Thanks guys,

 

 

Im assuming the silencer is stuffed inside the black housing. Thats gotta be a bear to get out.

 

but this doesn't answer my question, is there a removable silencer in the 5.4? I would rather just be able to yank it out, drop in a K&N, and call it a day.

 

There is no silencer inside the intake of the 5.4. The tuned chambers on the sides and the small opening of the restrictor on the end which goes into the fender serve that purpose. The DWV intake mod accomplishes the same thing for the 5.4 as removing the silencer does for the 4.6. It allows better airflow and more power.

 

So honestly, this is the same thing as a cai, sheet man if thats the case I am going to rip that beech open tonight and give it a shot. If it works out then I might cancel my af1 order and go with the e fans. This always worked on the mustang motors, I wondered why it wouldn't be the same with our motors. Also its was pretty much proven that cai were a waste of money with 99+4.6 gt's.

 

I must have done it wrong cause it just took me, if I say a minute its to long, with no tools, maybe its the steroids.

 

I just made a couple runs in front of my job (almost ran over a homeless dude). Its alright, its no night and day difference you feel a little more pickup nothing to drastic, it is like 90 degrees though in miami right now. Maybe with a k&n filter it would pick up some more gains. I didnt get to take it over 50 mph. I'll come back with more when I got it.

 

This is what you want to take out...

 

The whole thing, or just the smaller skinny black tube?

 

I took out my silencer the first day I owned my truck yes much better on the peddle response. I then cut the filter housing around the spring arm and down to the base to keep it held down after I installed a hi flow filter.
