Look at this POS silencer

2004 F150 2V 4.6L








I can't yank it off because unlike MN12s which still retain their stock CAI, I would lose it and start taking in hot engine bay air. Guess I need to do something about this, lol.

They call that the Gotts Mod on many f150 forums, it's on my to do list. It's also controversial and some idiots claim dispite it being before the maf that it causes a lean condition.

Basically the solution to the fill in the blank that you've left is to go to lowes or home depot and buy some PVC pipe and a rubber coupler to complete the delete.

Actually I was thinking about getting a cobra air box that way the snorkel will make a 90 turn into a spot where it can grab air from the front.

That won't be too much of a restriction, since it's the same size as the throttle body. That peewee sized silencer on the air box is another story though.

Oscar, cut it off right where it meets the inner fender. I did that on my old '98 F150, and it gained about 1/4" in ID over the stock piece. The "silencer" portion is where it's necked down after it goes through the inner fender. Or you can remove that entire "silencer" section and just replace it with a short piece of flexible air ducting hose. That's what I did on the old Navigator.

Anything has got to be better than that silencer. Im not real familiar with those trucks, is there a way to run it closer to the front without having a ton of intake tubes?

I did that mod to the airbox. The hot air should reduce pumping losses in normal city driving. Not really worried about the hp right now.

The one on my ranger I just removed and swelled a piece of exhaust tubing to fit. That one won't be so easy.
