The new "Gotts" intake on a 5.4 is VERY exposed, about 3-4 inches.

I don't really think the intake has changed at all on the 4.6L 2V since 97.

Yup, even the older 5.4 2V used it. I'm not sure when they switched over to what they have now though(with the square filter).

Probably when the 5.4 3V came out in 2004.
In 2009 it was changed again.

That is what I thought but wasn't sure.

Yup, that's mine with the big ol filter box. Picked up a 3" flexible coupling yesterday but wasn't able to find the PVC pipe. Will try to get to some other stores this morning.

There's GOT to be PVC pipe in Home Depot or Lowes. You need 3", Sch 40 stuff. This is "standard" cold water supply pipe for homes. Failing that though, you COULD use the grey Sch 80 PVC electrical conduit pipe. It has one end that is "flared", which of course doesn't matter since you won't use that end.

I'd be a bit leery of the flexible stuff. Some people have reported that it "puckers" in under the effect of air passing through which would actually restrict airflow.

Heck, try running without the snorkel for the time being. Wont be any different than a CAI with nothing more than the airdam.

Oh no, they did have PVC just sold out of the size I needed(sans a 10 foot piece). I'll get it at another HD/Lowes.

What is "Sch 40"? I was just looking in the Plumbing department.

[Jackpine]

It's just a designation that will be printed on the pipe itself. I THINK it relates to pressure and possibly temperature capacities. It has fairly thick walls, which you need for rigidity. The SCH 80 electrical conduit seems to be identical in wall thickness.

There's another white pipe "SCH" designation that is quite thin-walled. I think it's for waste (drain) pipe only. Stay away from that.

Schedule 40, I think that is just how they catorgize the strength/thickness. I got a 3 ft section in the same section as the flexible 3" fitting.

Well between me and Jack we should have every possible reason for the name.
