Using rubber for intake tube
Considering making an intake for my truck. Don't want to spend the 110 for the kit when I think I could do it myself for a lot cheaper. First off, is it worth the power to make an all round tubing intake over removing the snorkel and keeping that kinked up hose deal that goes to the turbo? and my main question is, can rubber handle the heat to make the intake? I found the perfect hose at intakehoses.com, which says their rubber is rated to 250-275 degrees. Is the heat from the turbo gonna melt this stuff? could do the whole systme for about 40 bucks....
High quality silicone hose, or?
I'd use high quality silcone hose but too much $$$, rubber maybe ok for awhile.
Snorkel in fender, or? What airbox do you have cylinder filter or panel? If it's a cylinder filter (RPO K47) you would be hard pressed to gain much of anything relating to performance or economy, it's a flip of a coin high flow after market filter, or stock filter?
Outside of retro fitting a Douglas air filter canister system effort insulating airbox is worth the effort. I used aluminum faced foam layered around the box to reduce radiant heat. Wrapping downpipe, or ceramic coating further reduces heat in engine bay.
