K&N cold air intake

[@californiajeeping]

I'm quite familiar with dirtbikes and offroad riding. I have a WR250R and KTM 1190 Adventure R. WR runs oiled uni filter and KTM runs the full Rottweiler oiled intake.

Yep I have had a ton of husqvarna and beta dirtbikes that I would plate and ride around. Few supermoto's etc. All had notoil or whatever version of foamed oiled filters. You just clean them often and they filter just fine.

Thanks ShadowPapa for your various posts on K&N and other oiled air filters. I know you must get tired of posting the same thing over and over on this topic, but I for one feel like a dodged a bullet thanks to you!

He doesn't get tired of doing this crap. He loves it. He's retired and got nothing better to do.

Looks like the pre filter is filtering. I’m going to grab some notoil filter material and upgrade the pre filter.

How are your IAT before and after ?

There is no change really. There isnt a power increase BUT when you first roll the throttle on prior to a downshift it spools up and hits full boost a bit quicker.

I imagine with a derringer it will be better. I am going to definitely look into pulling the CCV tube OUT of the intake stream a bit. It sticks WAY into this intake. Likely to prevent a CEL due to the larger diameter intake tube and less vaccum on the ccv?

Something to look into for sure.

I agree on oiled filters. I've read the studies and even casting that aside, I just don't like messing with an oily filter.

I run an AEM Dryflow cone filter on my TJ, with a sock over it. What you're paying for here is the K&N intake and it looks pretty decent and the ones I've seen in the past on other vehicles always seemed pretty quality. I don't see why you can't just replace the cone with a different brand of your choice. Unless they're doing some weird proprietary sizing thing now or something.

Nice filter on a stick. I’d have to be pretty desperate to spend $400 (i.e The military when approaching the end of the fiscal year…”if I don’t spend it this year, I won’t get that much next year”) before I’d buy another one of those. Looks neat though.

I bought this used a guy on FB traded his sport diesel in for a mojave. So 300$ all in.

People get hung up on oiled filters but what do you think the PCV is doing to your intake :\

spewing oil right into the intake. Ive run oiled filters on everything ive owned and never had an issue.

Hello all!
I'm between 2 options for a cold air intake system:
1. K&N series 77: https://www.extremeterrain.com/jeep...ow-performance-cold-air-intake-77-1576kp.html
2. S&B https://www.sbfilters.com/cold-air-intakes/jeep-wrangler-jl-3-6-intake-75-5121?variant_id=304

Do you guys have an opinion? Which one would you get?

Thanks!

Omar

Hey Omar, this is the Diesel section. These oil burners are talking about CAI's for the 3.0 diesel.

Since Banks made a tuner for the 3.0 and didn't bother with an intake setup,

I was going to say something, but you beat me to it.

It's not the oil going into the intake that's the issue. Oiled filters have a more porous media and rely on the oil to catch particles, whereas dry filters have a denser media and filter smaller particles. (generally)

If one thing is better than another then it's better. But I honestly doubt you'll ever know the difference between one or the other over the life of a vehicle, unless you're constantly operating in really dirty environments.

But I'm that guy that runs no filter at all on his turbo charged car half the time, so what do I know lol

I’ve run a k&n filter in a couple applications, built 250R raced motocross, pleated panel in stock air box 99 XJ, CAI 99 XJ.

it’s all dependent on application, my 250R I rebuilt every year, clean every race/weekend and was good. Stock air box w/pleated on the XJ, was ok so the CAI must be better.

Picked one up noticed more growl, a lil SOP raw powa. Ran it for ~50k with clean/re oil every 3-6 months. Took the CAI off to install a bigger throttle body and notice a fine dust coating inside wall of the TB. Figured that’s not good so went back to stock air box and pleated K&N. With the bigger TB it all worked well with the header, and SS exhaust, etc etc.

That being said the one pictured above looks like a better system than the cone filters alone I’ve used in the past. If you could continue to report future findings it will help the community make informed decisions in the future. Thanks for posting the pictures!

My bad! I'll look for the other thread. Thanks!

FYI everyone scared of KN filtration. This Donaldson power core fits ?
