Intake / PVC
A couple of years ago I bought an intake kit that had a "chrome" pipe. After two years the chrome doesn't look to good and it has spots on the inside. I want to replace it before it causes damage, and I was thinking about using plastic PVC pipe (white). Do you think the pipe could take the heat from the engine compartment?

Check out my gallery I have a big hunk of pvc for my intake, so far I haven't had any problems with it and its been there almost 10,000 miles.
as far as a chemical problem kwik. look at the glue you use to hold it together, that doesn't eat it up, and the stuff is used for sewer piping and it will tolerate that, so I would think that the only problem it might have would be a heat issue from the engine, and so far i haven't had any with mine.

I thought about exhaust pipe, but it's a lot more expense then PVC and probably harder to find in the diameter I would need.

I went to a place called six states and got a piece of 45degree 4" exhaust. Cost around $20. Looks decent and don't have to worry about anything. I had a hard time finding a piece of pvc without a flare on one side. Granted, if I were more patient I could have found a piece but I had my massive filter at home and wanted it on the truck.
As far as being hard to find, any exhaust outfit will have or could point you in the right direction into where you can get the tubing.

I would be hesitant to use PVC simply because I'm not sure how it would handle the heat in the longrun under the hood. Also, I know for sure exhaust tubing can handle the heat. It may work fine, but why bother when you can get a piece of exhaust tubing for a relatively little amount of money.

The inside diameter of the exhaust pipe would be larger then a piece of pvc which means better flow. My exhaust came with an extra piece of 4" stainless that I used, I still have some left over but its straight not 45

I do know that schedule 40 PVC waste pipe is not rated for hot water , but I'm not sure it couldn't stand under hood temps . As long as some of ya are already running this setup maybe you could keep tabs on it and report back as to how the PVC is holding up .

I'll have to measure what size pipe I currently have, it's straight and has no bends.

DWV pvc would work fine. Heat shouldn't be an issue, just stay away from the abs pipe (black) That stuff melts fairly easy and become brittle after it is weathered. Finding the correct size tubing might be a problem in pvc, the outside diameter of 4" is about 4 5/8". Another option maybe 4" copper check a local supply house see if they have a short peice and 45*

If you look in my gallary (https://www.ford-trucks.com/user_gal...=14503&width=0) it's a straight piece of tube, no bend.

I had to do some custom intake plumbing on my 66 Jeep when I put the EFI 351 in it and used various bits of PVC. This was about 7 yrs and many thousand hard miles ago and It is still holding up just fine.
