Hi all, I’m in the market for a different air cleaner system. Right now I have a k&n open coned filter. Really like the sound of the turbo spooling up. But I really would like to get the intake air out of the engine compartment heat for the summer. Might be putting the k&n back on in the winter, really like that turbo sound :p. Any suggestions? Also do not have the plastic factory air duct In the fender well. Thanks Gus.

If you can locate a k47 air intake from a 97+ year chevy diesel you will be ahead of the game. There are gasser versions of the k47 but it will not work. It has to be from a Diesel
Otherwise the S & B CAI w/ dry filter is the secondary choice

Might want to watch this before running your K&N filter long term.

sounds good OK, what do you think of this one. You can put the flex hose anywhere.

The Apollo incorporates a K&N famous cotton gauze filter which is removable for periodic cleaning and provides the benefits of an open cone filter and standard air box in one unit. Heat buildup is reduced which keeps the intake charge cool. Smooth internal features minimize air turbulence and maximize air flow. The Apollo is ideal for normally aspired engines up to 250BHP and turbo engines up to 350BHP. It comes with a standard 70mm base flange with a range of optional stepped adapters available to allow fitment to other intake sizes.

    Sorry I was very disappointed in the product, it listed as a "Universal" Well it isn't! A 3" tube is far from a universal fit! It didn't come with any other fitment couplings! it won't fit my 4 1/2 " oval inlet or any other type SO Universal it is NOT! I would not Recommend this product to any one! I'd like my money back

The K & N systems are about the worst you can use for a Diesel engine.
The reason behind this is because of the cotton fiber.
The oil and dirt etch into the cotton fiber and no matter how much you clean it, dirt and oil remain and over time reduces the air intake into the engine making you lose power and performance

What about a dry filter element?

A dry filter element is best but a cone type system that allows hot engine bay air into the engine intake is not good for your engine at all.
You want an intake that pulls outside ambient air that is away from any engine compartment.space.
Diesel engines love cold air, colder the better

Yes. That k&n filter kit (RC-5052AR) has a flex hose you could probably route it to the outside. But I’ll have to research it a little more, the filter doesn’t look that big. Thanks OK. for the input.
