 ​Do you use a K&N style filter? What are your thoughts on them?

 

Air flow is very important to the performance of the engine. The truck I have now came with one, I have never used a K&N filter before. Today I had to clean and recharge the filter. No big deal really.

The previous owner of our 2014 Jeep installed a K&N filter.  I don't know how to clean it and I'm sure it needs it.

How is it done?

They make a service cleaning kit. First is solvent to rinse old oil and dirt from the cloth pleats. Then when it is dry you re-oil with the Red K&N oil. Just don't overdo it with the oil.

I've had probably half a dozen K&N filters on various vehicles over the years. Currently the only oil/cloth filter I'm running now is in the Corvette and it is not a K&N.

From what I've read over the years a good factory air filter is better then a K&N as it filters better but the aftermarket oil/cloth units allow more airflow which gives a slight power increase but in turn allows smaller dirt specs to enter the engine. Oil/Cloth units are reusable of course.

Last fall I picked up a new factory replacement paper unit for the Ford F-550 from an auto parts store down in Lewiston, ID. The list was $135.00 for a filter. Not from a dealer. He asked if I'd taken my heart medication for the day before telling me the price. The manager gave me a huge discount down to like $45.00 for my service in Law Enforcement for over 20 years.

 The K&N filter recharge kit was $12 at my local NAPA. It took about 1 1/2 hours to complete. That includes drying time. After cleaning it, it needs to be completly dry before applying the oil. Then the you need to have it sit for a good 20 minutes befor einstalling. That 1.5 hours only included about 20 actual minutes of work, the rest was drying time.

 

I did need to clean my filter twice as it was pretty dirty. Also, I only put oil on the outside (upstream side) part of the filter. I watched a few videos that recommended doing that.

Take white t-shirt and wipe the inside of your intake. If you are getting dirt in the intake tract, your K&N is not doing its job. Most of the guys in dusty environments do not like them, but the performance guys have better feedback. If your K&N is still in your air box, it will not make much flow difference. If it is set up as a Cold Air Intake, it flow better but will also make intake noise when operating.

Good advice from Bedlam. I use an Airaid and I check my intake hose everytime I clean and reoil my filter.

A good friend had one on a smallblock Silverado a few years ago. His assessment was that whatever change there might have been in output wasn't worth listening to it. For whatever it's worth...

On Ford 6.7 Diesels, beware of after market air filters. They may not have rigid enough structure and get sucked into the turbo. That being said, I am a K&N fan. But not after seeing the one for the 6.7.

My Cummins 5.9l has an AFE deisel power performance air filter. It looks cool as hell and I did not have to pay for it like the previous owner. Can't see any major advantage to having it though. Also have a performance 4 inch exhaust that will blast anyone in its path with a wall of powerful sound but has no real performance benefit but lots of bragging rights! Performance is often NOT practical or economically, beneficial. If you do some reading on the performance pickup forums it is common knowledge that performance filters and exhaust for that matter do not show real world dyno tested performance increases claimed by performance manufacturers. Negligible performance for a large outlay but everyone has to have one to be cool, so don't be a chump and cough up for a K & N already. Lol!

Rich, while I voted for performance filters, I would strongly recommend removing the K&N as it does flow better, it also lets more dirt through. There are very good "nanofiber" filters out there that are cleaned using simple compressed air--low pressure--then replaced after several years. Amsoil used to carry them, and I think they were made by Donaldson---but I could be mistaken on this.  K&N sells filter cleaning kits that can usually be purchased from your typical autozone stores

If you are running any kind of tuner in your truck it is imperative that you increase your air in and exhaust out to keep your exhaust and turbo temps down. That is why the cold air intake units and large exhaust are needed.

Thanks.  I found the K & N YouTube video on how to clean their filter.  Went to Autozone, bought the cleaning kit,

The filter from the Jeep was thick with dirt.  It cleaned up very nicely though.

I put it back on and got a big psychological boost.  It really does seem to have more pickup power.  Maybe my right foot got bigger.
