Intake Upgrades

[shortstack]

here is a video/audio clip, of the ebay's version of the KKM
MAF adapter and cone filter

NOTE: THIS IS ON A 1998 4.0L SOHC, but it will at least give you an idea

You should never use a dryer type hose. It causes turbulance (bad). Use only smooth pipes, laminar flow (good). It is just basic fluid mechanics.

am i crazy or does the stock intake tube have ribs? not picking a fight i just dont see your logic.

It does, I dont use my stock intake it just sits on the front porch.

Imagine water flowing through the dryer hose. At low flow it flows into each dimple, fills up, and flows to the next. At high flow, it jumps and moves in a random motion. Now imagine a smooth pipe, at low flow, the water just flow constantly down the pipe. At high flow it flows straight with much turbulance. It is a bit more complicated, but this should do. Yes I am a professional engineer.

I looked at the sticky post and that looks ok. But, if the 4.0 doesn't draw that much air, would a simple K&N filter replacement be just as effective?

BTW, what will a BBK throttle body do for the X?

 

[unclemeat]

I run a K & N filter element with the hose pulled, works good for me. I may add a KKM in the future.

Just replacing the factory filter with a K&N makes some difference, but even going from a K&N drop-in replacement filter to a KKM or K&N cone filter is a BIG difference.

A larger throttle body won't do much without the larger MAF/MAS, larger exhaust, and probably the chip and programming to take advantage of it. Just using a cone filter and a catback exhaust is a lot simpler and probably more bang for the buck.
