As long as you can seal the ends and route it, there isn't a problem using it. It will survive the engine heat. There are rubber connectors available for Plumbing that could be used to connect the ends to the filter box and the intake.
No, it will not work for that.
In order to paint on PVC canvas you must prep the canvas by gently sanding some of the pvc coating off with a medium grit sandpaper. This will allow the paint to adhere to the PVC. Wipe the canvas clean and allow to dry before priming it. Once the primer is dry you can use acrylic paints to create your master piece.
As long as you have anti freeze in your car, you'll be fine. If you let your car warm up before running it hard cold air is actually better for it.
Most modern day EFI vehicles such as the 350z are equipped with either a MAF or MAP sensor. The 350z has a MAF (mass air flow) sensor. It is located on the intake pipe between your air- box and throttle body. Most manufacturers today use MAF sensors over MAP's because they are more efficient. You can install a MAP sensor, but would have to run a piggy back ecu such as AEM or UTEC. This is usually for high hp forced induction builds.
Originally a pipe cleaner's purpose is to clean tobacco residues in a fife. Though often pipe cleaners are use for handcrafting especially in Kindergarten. A more specific definition can you find in the following Wikipedia Article
A pipe cutter is the best tool to cut PVC pipe.
Yes, if it is rigid PVC conduit approved for electrical installations. Don't use PVC water pipe as it will be rejected if inspected.
No, do not use glue. Use teflon tape or pipe dope on the threads. You should also make sure you always put the male PVC thread into the female metal thread. If you do it the other way you will tend to split the PVC fitting when you tighten the threads.
if your waste pipe is PVC and your glue is for PVC . yes! but make sure to use a primer(cleaner) on the pipe first.
Absolutely Not!
Use teflon tape with a little pipe dope. If you don't ever have to take apart again then you can use glue which you are calling cement
Lead wipe a brass nipple into the lead pipe and then use a female adapter x PVC on the brass threads
Yes, for proper bonding of PVC pipe and fittings. Primer also code requirement.
PVC pipe is fine
The simplest way to build the snorkel is to take the measurements of the intake hole and buy PVC piping that would match the hole. Also, consider using pipe/hose that is larger in diameter than the stock intake to account for the reduced airflow caused by the resistance of the extra pipe/hose. Then get two pieces of flex pipe to make the joints, one for the intake entry and the other for the exit point. 1. Attach the intake portion to the flex pipe. 2. Use another pike of PVC pipe and route it to the desired are where it will exit. 3. Attach the other flex pipe to the end of the PVC. You can add a filter to the end or a box with wire mesh attached to the end. (I like screen door Mesh).
