K&N CAI Choice

[NGin402]

I have decided to go with K&N for my CAI. I want the 77-1529 because of the aluminum tube as opposed to the polyethylene one found on the 63-1529, but it has a different housing in its picture. Is this just the picture? If not, will it drastically affect performance?

The metal tube will actually hurt perfomance over the plastic one.

From what I understand the metal one will increase your intake air temperature over what the plastic one will, and heat kills horsepower.

EDIT: Figured out this part I posted. Just curious of the different box design would make a big difference in airflow.

^^^What he said.

Box designs and the more pronounced downward dip of the filter won't make any difference.

I have that K&N one on my truck and like it. Sometimes gets loud tho.

Even though one seems to have the air scoop integrated, and the other is just a box?

It's your truck, so go right ahead.

I find K&Ns to be painfully loud in the cab when under load. The comment above about metal pipe being a bad choice is correct. Engine heat will rapidly warm a metal pipe and pass that heat to the intake air more quickly. The purpose of a CAI is colder, denser intake air.

I'm sure you've heard of an inter-cooler, but have you ever heard of an inter-heater? There is a reason why they don't exist except maybe on an Snow Cat.
