Hello everyone.
I just purchased a2007 tls and was wandering if you folks could help me. the car only has 16,000 miles and I want to replace the air filter, right now it has a stock filter and I would like to know if it is worth it to replace it with a K&N filter or is there a better aftermarket air filter. I also changed the oil to mobil 1 synthetic oil 5w-20. Has anyone tried the 0w-20 mobil oil? I'm not sure of the benefit to go to 0w vs 5w. Any info I would appreciate it.

Hello sir I used to have a K&N filter before switching to my CAI and it seemed to work pretty well. As for the oil you may want to do a search. There is alot of info on different oil used on this site so I'm sure you'll find your answer here. And welcome.

Two things to keep in mind. K&N filters pass more air when new (or thoroughly cleaned) and also pass more debris in this condition. As they get dirty, they will filter a little better but pass less air. Another thing. They are oil-wetted. A small amount of this oil will make its way into the throttle body.

If any of this bothers you, go for an after-market dry element filter. A decent on is the Purolator A-25585 (make sure you get the one made in Israel).

In some vehicles the oil in the filter will cause a MAF sensor failure--even in new filters if overoiled from the factory--it happened to me and I took it to the dealer--they had to replace the MAF sensor and said to remove the oiled filter or next time I will have to pay for the service--I returned it to stock...

i have run a k&n air filter in every motorcycle and car i have owned for the last 20+ years with no problems...there is not going to be oil making its way into your intake....

so far, i am running a k&n filter, and i have mobil1 5w20 per the manual, mobil1 m1-110 oil filter and love it....

Keep in mind that 3G TL's ('04s and '05s) do not have MAFs.

How about the 2006 TL?

No Honda or Acura has a MAF (Mass Air Flow) sensor.

Honda/Acura's have always used MAP (Manifold Absolute Pressure) sensor for their engine management systems.

And MAP's are fairly immune to aftermarket K&N's and other filters with oil. The OEL filters for the TL are oil impregnated paper filters.

Look at the engine, see that black metal pipe going from the valve cover to the rubber snout tube- the one that connects the air filter box- to the Throttle Body

There are oil and unburnt fuel vapors in the valve covers- this is routed via that metal pipe, back into the intake- to get remixed and burned again. Its crankcase ventilation, part of a smog system that cars have used for decades, and it puts oil residue at/on the TB plate all day long.
So the small possibility of over-oiling at the factory is not a real concern. Over oiling at refill is a prob, so follow the directions.
The K&N filters smaller particles when new and has higher flow rate over paper filters. The chart shows up to 50,000 miles before cleaning required (unless dusty where you live- which is most of us- then do it once a year)
At 50k miles- it is still flowing as much air as most paper filters do when new

Everyone should be using TB spray cleaner of some type at least once a year.
Do it with the fuel injector- induction cleaning- seafoam or wynns are good stuff
Techroline bottle does help part of it, I have been known to use it as well,- especially if running chevron gas right then- You have to study the label to find the max effort doseage!
There are other things that need a direct vac port induction, to clean things spotless.
The gas tank method gets the injectors clean the best, a main vac port gets all the intake manifold, and pistons the way they need to be for max efficiency.
thats my opinion- I use K&N on all the vehicles and told the neighbors about them.

have used K&N in all my cars. I had a VOLANT CAI in my 05 Navigator..it actually was worse for gas mileage.. K&N FTW
