Someone told me that when I replace the air filter to use a specific brand because it was better quality and can't remember what brand or who told me. Really sucks getting old! Any suggestions?

 

I just placed a K&N in mine. Did it like 30 minutes ago, so can;t say how much better yet, but I've had a lot say that it's better than the paper filters and lasts a lot longer before it needs to be cleaned (mnd you not replaced as it just needs to be cleaned with their cleaning kit, which is like $8-10, but only need to do it once a year or less)

 

K&N seems to be the popular choice unless you are going the CAI route. I'm considering a K&N but right now I'm still running stock.

 

I've gotta say, in this day of electronics and computers, there is very little if anything you can do to enhance quality and performance by adding any small $$$ bolt-on components.
With that said, 12 years ago in the days of the XJ and Jeepin.com, I jumped on the band wagon and installed a CAI with K&N, throtle body spacer, synthetic fluids, FlowMaster catback with 3" exhaust, gears, 6" of lift, AA SYE, and so on.....
Today I still have that 94XJ and have realized over these past years that if I gained anything in power, it was more in my mind than real.
We traded the wifes 99XJ, back in Dec.06 for an 07JK 4dr. I've spent $$$$ on it from day one. An AEV front bumper, PIAA fog lights, Wet Okole seat covers, BestTop bikini and trailduster, Mopar rubber mats, doorsills, and sidetubes. A good claybar, Meguiar's waxes, microfibre cloths and the likes. At 3K miles switched to synthetic oils and lubes, but as yet have not installed any of the so-called power enhancing components. As far as the engine and drivetrain, we will keep it stock, and put our $$$$ elsewhere. I must have spent in excess of $500 on the bolt on engine mods alone on the XJ, and the only thing they made were noise.
Since that time, I've done alot of research, and I've come up with, Chrysler made the JK a pretty all-around quality vehicle in its stock form.
Just my rant.....

 

Somebody made a good point in another thread regarding K&N filters. If it flows more air, it's flowing more dirt.

I used K&N's in two Dodges and a Ford that I had. I saw no real differences in power.

It was just me, but I tended to let their cleaning go beyond what should have been. As a result the K&Ns were pretty cruddy when I finally cleaned them out.

I think it may be just more convienant to pull out the old and drop in new on a regular basis.

I think I may just stay with factory in the JK.

 

Lorrel, I am in full agreement with you about the uselessness of small bolt on power mods like intakes. The engine in my Rubicon has more power than necessary and with the lifetime powertrain warranty, I am leaving it completely stock.

So far, I've spent my mod money on things I will actually use and enjoy.

As for my intake filter, it is going to be an OEM Mopar paper filter.

 

My gas mileage increased with a K&N drop in. 50 more miles to a tank.

 

How many miles did you have on your JK when you put in the K&N?

 

Two very good points.


Unless it has a larger surface area but the same partical size filtration. Then it is working better longer.

But I still agree that it may be just easier to drop in a new one on a regular basis.

 

Thanks for the input. I think it was the K&N but the stock argument also makes sense. I do like the idea of better gas mileage at this point.
