air intake K&N?
so iam about to put the mc2150 on my 89 wrangler, go the K&N site and ask the tech folks there for the air intake. Was told they dont make them for carbuerators, but i have seen them sooooo.... do i have to make one?

Why do you want K&N? They let tons of dirt into your engine. Just get a paper filter and call it a day.

You will not beat the el cheapo AC/Delco

Ability to capture dirt:

Dirt capacity:

But go ahead and buy the K&N. Their marketing is very good and you might get a sticker.

that's because K&N is ment more for HP/ Less restriction in airflow but most people don't know it

I have a K&N (put on by the PO) and wish I didn't. I cringe at the build up of dirt/mud/crud that forms on the little bag that goes over the filter. I can only imagine how much is getting through and raising an army, ready to nuke my motor.

I'm planning on figuring out a way to get back to a sealed air box.

Dear Op,

What you are looking for is a Carburetor plenum such as this------->

As aforementioned cold air intakes have their pros and cons. I run a 12 dollar air filter from Autozone. If you would like to see my setup pm me and ill snap some pictures for you.

EDIT: You can also use these plenums to build a snorkel setup if you're into those goofy giraffe necks.

I have a drop in k&n air filter in my stock box and keep a close eye on it, last time I looked in the tb I didt see any build up.......

thanks for the replies, always wondered how K&N got more HP while still trapping dirt, now i see how they do it, or don't as the case may be. Since i live in a desert i had better go with better filtration. Thought that at 7200 feet i needed more HP but i drive a wrangler, so am used to going slow anyway, ROTFLMCO!!!

YJ4LIFE 05-24-2013 04:04 PM when I put those on carbed or TBI vehicles I start with a paper filter, find the size I like then later when replacement time comes, get a K&N the same size. only burn is i've had mechanics replace or steal them and put a paper filter in their place.

The stock air box IS a cold air intake and the flow is actually very good.

As a former Colorado resident who defected to the desert southwest, an air cleaner will do virtually nothing to help with the lower barometric pressure associated with high elevations. Absolutely nothing. The only thing that will help is a turbo or supercharger.
