air filters
 

Let me start off by saying i am a current user(on my jeep) of the K&N drop in filter with no problems...but two weeks ago purchased an '08 FJ-TT...that i love. Have been reading and studying boards about the best care for my cruiser. I was about to buy the trd cai when i began doing more research on various filters both air and fuel. I got to thinking maybe the K&N and TRD filters are just overkill. IF i was driving a top fuel dragster on 5 second runs i would need a lot of cfm going into that engine...but the f.j and even big block v-8,v-10,v-12 engines dont consume that much air. And with all the offroading fj's do...do we not need better filtration v.s more airflow. in other words the paper filters flow as much air as any f.j would need...i too found this. http://www.nicoclub.com/articles.php?id=180100 to each his/her own. just my two cents. do not mean to offend anyone...thanks.

KNNs are okay. i prefer stock toyota filters though.

Hey OZ . i love that front bumper

Having used both the TrueFlow and the K&N, I HIGHLY recommend the TrueFlow. It does not get gunk on the air flow sensor like the K&N will, and the filtration is excellent!

Thanks guys sounds like a great idea. I think alot guys found out that when they recharged their K&N's they may have fouled the sensor.

^thats happens when you over oil :nono:
i have had mine for ~4 years now and havent had an issue.


i recently purchased the cleaner kit it includes an spray pump, not the straight oil now. should help the amateurs out.

K&N filters suck. They sure sound cool though... I will stick with my denso paper filter. Perhaps upgrade to a new amsoil nanofibre filter...

If they made Amsoil Nanofiber airfilters for the 22re I would have one!

thanks. now i just needa figure out how to make a skid plate to cover the oil pan and everything lol

Wow, I have never read such bad comments on the K&N. I ran one for a while and then switched to the Amsoil. But now in my "new" truck, I am back to K&N. I know they don't filter as well as Amsoil, but why do K&N now suck?

What about Trueflow??

Because they let so much crap through, that is they don't filter as well as stock.
This is well know and documented. Nothing at all new here.


I don't know why so many think that they, somehow, need to "improve the intake flow". We're talking about an engine that moves as much gas (air) as a gnat fart.

i would go withthe k&n i love mine ive heard they dont 'filter' the air as well but they flow really good i know i felt a little power increase with mine. and its been almost 2years no problems yet

TrueFlow is the best filter I have ever used, night and day difference from K&N, my throttle body stays clean!!! ...and that's just highway driving. I clean it every 10K. Get a TrueFlow, you won't be disapointed.

Huh... TrueFlow... I had never heard of them until this thread. I will ckeck it out - thanks!

Stock fuzzy filters work surprisingly well. Get the debris trap from the new FJ offroad package if you don't already have it.

HUH???

Do you have a photo of this thing?

Im pretty darn sure they do ;) Us 3vze guys are outa luck though :(


The reason K&N filters suck.... hold it up to light, yes you can see light through it... Im sure dirt will find a way though them gaping holes!

Not worth the 1hp gain for a shorter engine life..
