K&N Filter - Yes or No?

In my FJ-62 I have found the K&N oil around the Air Flow Meter, and it has been roomered that the fluid may foul the AFM. This doesn't apply to you, but I thought I would throw it out there.
 
My mini truck came with a K & N filter. I've not been too impressed. I have to clean the oil that came off the filter and landed on the Mass airflow sensor. It didn't quit working, but I wondered what particles were in the oil that went through my engine. This happened over time, not all at once. And I noticed no power loss switching back to a Toyota filter.

Doesn't the Toyota filter flow just as many (or a non-noticeable difference) CFM?
 
My motto is a little cliche but none the less; 'If it ain't broke, don't fix it.' If your current air filter works well then don't replace it. When it comes time to replace it however, put a K & N in.

Don't spend money if you don't have to.

Thanks cruiser. Any recomendation as far as TRD or K&N?

I have the TRD because in a side by side comparison the TRD is larger (more filter area). I don't think the FJ60's use the same filter as the BJ60's so I don't know if the same thing applies.
 
I would recomend the K&N. I run them in everything I own. However I have noticed better results in different vehicles. I could not tell you how much they have helped my FJ40 or 60 as I've never driven them without one. My 94 Dodge Ram w/5.2 noticed a 10% gain in MPG as well as seat of the pants power. That was definitley worth the $60. 2001 Subaru outback had a noticable difference in both as well. Waiting for K&N to develope one for our 2005 Outback.
 
Im not certain you can ever truly tell. You have to simply understand that the K&N is passing MUCH more air more easily than are stock lower quality filters. That is simply fact.

Agreed. I have been running a K&N on my 60 since I got it, and yes, I did notice a seat of the pants difference when I put it in. I could tell it was breathing much easier, and the pull during acceleration felt stronger. Didn't do a thing for mileage. Some would say I am full of crap...well fine, sling it. All I can do it give my experience. I run K&N's in all my vehicles. It made a large seat of the pants difference in my wifes 2.4L Solara, and hardly made a difference in my 2UZ-FE 4.7 Tundra. No mileage gains either way. I don't believe they allow more dirt in, but I agree that they are oily. Right after you oil them, you have to clean your MAF until the oil dissipates, especially if you use to much. Cleaning the MAF is no big deal, but the 2F doesn't have one...I speaking to newer vehicles.

But regardless, look at it from an economical point of view. Because you can clean the K&N, your saving money. I forget what it is on the Land Cruiser, but for my wifes Solara, two paper filter pay for the K&N, and three paper on the Tundra pay for the K&N.

Just put a K/N on the 40 - have had one on the 60 for a year - love it / not really for the "power gain" but because I live on dirt roads and would be changing the filter all the time -
 
K&N air filter = no. Had one for a while, decided to get rid of it (woke up and smelled the poopoo) and put a stock filter in with ZERO performance difference.

K&N oil filter = go for it. I will only use K&N or Toyota oil filters. The K&N oil filter is built for excellent filtration and flow.

Exhaust is a big job if you want to get the most out of it. As of now I've got a 2.5" cat-back system with a Flowmaster 50 series. When I return from my next deployment I'm hoping to order a set of headers from Man-A-Fre, their downpipes, and have a new duel 2.25" system built using Flowmaster 40s with an X pipe upstream of the mufflers.
 
Thanks everyone for you input (so far).
I live in Denver so I think a better air filter that lets more air through will help my 60 run better at this altitude.
Even though a lot of you say say that K&N is a waste of cash I will give it a shot..., though I'm leaning towards a TRD air filter just to keep it in the family.
I will follow up once I make the change...
 
Just my $.02. I own a 85FJ60. I bought it stock with a blown exhaust/intake gasket. Put a SOR two pieece header and stainless exhaust on it. Also de-smog. Noticed a huge power gain. Put in a K&N and noticed a little more power gain. My bro then gave me a MSD coil and this also gave me a little more power. All of my friends who own 60's have basically stock 2F's and notice a huge difference in power between my truck and thiers, as do I. Definately did not increase MPG, but that was not what I was going for. Is it worth it for a stocker? Don't know. But my motto is if it's broke, fix it better. As far as power gain goes, the coil increased power more than the K&N, but is also pricier.
 
From my personal experience the exhaust is the best place to start with mods because flowing more air in is pointless if you cant get it out.I run K&Ns in both my cars and I saw a huge improvement but these are the cone style with the cold air intake.I also put one on a 90 4Runner with 6cyl engine and didnt notice any improvement at all. But the money saved on filters is nice since the cleaning kit is about ten bucks and is good for 2 or 3 cleanings.
I also have one on my cruiser but it doesnt really count because its mounted to a holley carb which did give it a huge increase in power. :D
 
i agree with you on the trd filter. a k&n is good but the better air flow and the fact of it being toyota of the trd makes it worth it.

good luck
 
Does anyone know a good source for TRD filters. I have found a couple, but if you know of a local place in - or near Denver area please lemmie know!!!
Thanks!!

This seems like double logic, don't you think. The more it flows, the more stuff is going to get through, including gunge. Same principle works for the air filter. So pick your poison, more air or cleaner air.

With that said, I run K&N air filters in both my trucks. The 62 is on road only. The 60 gets the K&N during the winter and a paper during the summer, as I run on forest roads with very abrasive dust, which has already torn up my valves and seats once already.
