Cold Air Intakes for First Gens
I'm wanting to do a CAI on my first gen. 91.5, intercooled.
Do you guys have an opinion on the Amsoil 4510 Nanofiber Air Filter with a precharger? I've only found one company that make CAIs for 1st gens: 1st Gen Cummins Cold Air Intake - Icebox Cold Air Intake Systems Pretty ridiculous price. Since I don't have a welder what do you guys think it would cost to have someone fab it? Is a closed box better than open? I've also seen people use 2nd gen kits, I think? What do you guys think is the best to lower egts and increase power? And how much of an increase could I excpect? |
You might see quicker spool up and might see some increase in MPG. You may see lower egts by 100-200 degrees if you lucky. I would just fab my own up just buy a good filter and use some pipe and fab one, or have someone fab you one. It will be cheaper than purchasing one, I believe. :c:
The cooler the air the more dense the air, which allows more potential for that air to produce power. So this means a closed off system getting cooler air from outside the engine bay should produce more power. :tu: |
I would do a search and you can find alot of pics of what guys have done to their trucks for a homemade intake. There's quite a few threads on it.

Aside from the elbow/tube on the bottom. |
No the stock inlet tube is not real restrictive. The most restrictive thing is going to be the filter element. You can just replace with a higher flow filter element in your stock box and get close to the same flow as an aftermarket intake system.
