No, if you increase the diameter of the intake tube, the air velocity decreases! In a lot of cases, this causes the MAF sensor to sense the incorrect volume of air flowing. The OEM intake DOES NOT restrict the amount of air being pulled by the engine, to confirm this, try measuring vacuum in the OEM intake tube at WOT, and high RPM!!

ALL S.O.P. dynos are inaccurate!!!!! More noise does not equal more power!!

I don't think the velocity where the MAF is will change. My MAF is molded into the air box and the diameter there didn't change. Say what you want but I know the truck runs smoother and stronger. The accordion bends have got to make a lot of turbulence. Besides I am only showing something that I thought others would be interested in and not to prove anything.

Was your last line really necessary? Leave yours stock then.

Have you heard the term "placebo effect"?

You can use a sewer pipe for an intake tube, and it won't flow any more air into a N/A 3.0L than the OEM intake tube!!!!

Try what I suggested with the vacuum measurement if you don't believe me!!

It's not that I don't believe you I don't care. You have proven yourself all knowing to someone that wanted to show people something I thought was cool. I have been told by you...my intake is a failure. Satisfied. Letís move on.
Read the other posts, they understood what I was trying to do.

Believe me, I'm just trying to keep you, and other youngsters, from wasting your money on useless mods! I think it is good that you have shown an interest in your vehicle!! With today's CAFE standards, ALL vehicle manufacturer's designs are extremely efficient! I'm trying to tell you that the OEM intake/air filter is not limiting efficiency & power, and measuring vacuum in the intake tube is just a way to prove it.

One more thing to keep in mind. The 4.0L uses the exact same air filter as the 2.3L, and 3.0L. With a N/A engine, the displacement will determine the volume of air the engine will pull (and RPM). So, if this OEM setup is fine for the 4.0L, it's over designed for the 2.3L, and 3.0L!

I'm 44. At least that's one compliment you can give. Youngster....I havenít heard that in a long time. Click on my name (vindex1963) and read.....oh yea thanks for setting me straight.

I can take it apart this weekend for more photos if anybody is interested.

Did the longer tube come with the bung for the crankcase air tube already in it? How did that work?

No it didn't. The 45* tube didn't either. I ordered rubber grommets and drilled my own holes. The tubing has about a .05 wall thickness so it's pretty strong and easy to drill out.

Thanks, I have gotten TONS of P.M.s on it. All vacuum lines and sensors are present and functional so going through smog tests shouldn't be a problem.
The truck runs very strong from 3000 on up and yes the intake has a good sound to it at WOT.

The tubing was getting extremely hot so I header wrapped it. I think it still looks good. Now it's more functional than it was.

Do you think Ford might have known what they were doing when they used the material in the OEM intake? What you have done is raised the temp of the air entering the engine, above the temp that the IAT sensor thinks the air temp is. Not very good for efficiency or performance! What you wrapped your intake tube with has a certain insulation "R factor", and with enough time, your intake tube is going to get as hot as it does without anything on it.
AND, if that wasn't enough, you have reduced the cooling effect from the air flow through it by reducing the velocity of the air flow! NICE!!

He sent me the same message in a P.M.
There are meds for obsessive compulsive disorder. They can quiet the voices.

The desire to continuously do "performance mods" would fall under OCD.

This is especially true when you do mods that actually screw things up like this one.

Guys, leave it civil

every person is entitled to their own opinion, but bashing other members is not allowed.

If a owner of a vehicle wants to mod it beyond stock, they have the right to make that decision. Changing an intake tube inst going to make the vehicle dangerous on the roadway, so give out your advice on the subject and leave it be
