IAT Sensor

[purdyboy3]

I posted a while back asking about the tread size of the IAT sensor.

Today I finally got around to looking for a tap.

Tap size is 3/8-18.

This is good info if your building your own intake or just relocating your sensor.

Thanks, great to know.

Okay, I got a question for ya. My PCV hose runs to a steel nipple that is "threaded" (I say "threaded" because it's not really possible to thread steel into rubber, but you get the idea) into one of the rubber couplings on my powerpipe. With my new valve covers, I'm just gonna run a straight breather, and eliminate the hose. What could I use to fill in that hole in the coupling? Could I use some sort of putty or RTV sealant or something? If nothing else, I could leave the nipple in, and JB weld the end closed, but that would look gay. Any ideas?

Try to find a threaded plug.

Something like this

You can find them at Lowes or the Depot.

Does that help?

See attached file for thread size finder.
Just make sure you print the actual size.

When I had to open up the thread in my Ebay CAI I had to find this out for myself. BTW, the 3/8-18 is a NPT (National Pipe Thread) tap, not a standard UNC (3/8-16) or UNF (3/8-24) straight thread.

BTW, that's a neat chart, but all the info I need is in here. . .

My IAT does not look like it has a tapered thread. It looks like a straight thread. Any thoughts?

 

[illwood]

Looks can be decieving. Do you have a micrometer or dial caliper to verify?

It would make sense for Ford to use a pipe thread here because a pipe thread seals because of the taper. A straight thread wouldn't necessarily seal against air and this would be an air leak after your MAF.

unfortunately I don't because I am at home today... Would the taper be that slight though?

 

[illwood]

Pipe threads are only about 1.75 degrees of taper measured from the centerline according to Machinery's Handbook. I don't think that would be visible on such a short length of thread.
