Are there any increase in mpg or hp?

Dealer is charging me $70 to replace and I wanted to see if I should stick with stock air filter or get k&n.

Thanks!

 

no increase in MPG or HP.
the factory filter outflows the throttle body.

and why would you spend 70 dollars on a part that cost 15 dollars and a few minutes of your time?the dealership is gouging you big time.

 

It really is pretty easy to swap out your own filter. Try it out and save your $$$$.

 

Thanks. Definitely not going with the dealer.

 

I bought the K&N filter to use while I was waiting for the CT icebox to come out. I got it because it is reuseable and it is fairly easy to swap out. I did not feel any power gains or MPG gains. Right now, it is sitting in my garage collecting dust inside the factory airbox. If you know you are going to keep your car long-term, then get one since you can re-use it. If not, just stick with the OEM filter.

 

^yes, but because the pleats are bigger to "let in more air" you're also letting in more particles.
however, there have been no documented cases of engine failure with K&N filters.

if you buy a filter from autozone or the like, they will even install it for you.
just know that autozone filters(fram and the like) arent made with the same quality as OEM.

I replaced an OEM filter with a Fram filter and noticed that the OEM filter was a little bit better put together.

 

I bought mine online for $40.00. No difference in Performance or MPG, just a way to clean and reuse air filter.

 

Google this...
change engine air filter acura tl
There is a good YouTube video to change the filter. I am on a tablet and I can't paste URL.

 

^this&that

I've done a side by side. The OEM is multi-medium filter with substatially better flow and filtration.

HMCo engine products are high quality. The cabin air filter on the other hand...

 

I did the filter a while back but haven't noticed any gains in hp or mpg. just changed it for the ease of washing and reusing

 

Ive always put K&Ns in my car. Not for HP or MPG gain, but just because I keep cars a long time and they are much cheaper in the long run to wash and re-use.

I am now having second thoughts.

I have had to go to a city about 100 miles away from me a few times for work recently. So the last time I decided to clock my highway-only MPG on the trip back on my Trip B. I came in at around 31Mpg (I got 27 R/T on my Trip A). I must throw in a disclaimer that the city is 1,000 feet in elevation above me, and has a slight pass, so I go up 1,000 feet, and then down 2,000 feet. So I am getting higher than average gas mileage due to the net drop in elevation.

I did the first clocked trip with my K&N Filer that had been washed recently. Since then my car went through emissions testing, and they failed me for not having a factory filter (It passed otherwise) so I had to buy a factory filter and bring it back to get my official pass. I planned to remove it and put the K&N back in, but decided to use it up first.

I just made the same trip yesterday with the factory filter. I was amazed to get 35.5Mpg O/W and 30.2 MPG R/T.

In both cases I filled my tank before leaving home and reset trip B as I got on the highway on my way back. Both days were in the mid to upper 80s, and both times I drove all the way home, A/C on auto and set to 70, so it was about 95 miles highway, and 3 miles city. Both cases we the same day of the week and mid-day, so light traffic. I also filled up with Conoco premium both times.

Of course there could be plenty of other factors and I am sure traffic patters were probably different (I didn't keep track of how many people I passed, lane changes, etc.). But I was still shocked by the 3-4MPG difference. I think I will now stick with factory filters.

 

I just put a k&n typhoon short ram intake into my '13 TL 3.7 and the throttle response is noticeably better and the mpg stayed the same with me driving a lot more aggressively due to the absolute joy I am having. I am loving it and would HIGHLY recommend you installing one they are worth every penny.

 

The Acura filter costs $20 here in Canada but it is (i'm sure) the same part used in the U.S. It appears to be a very high quality item. As others have said, it is easy to change and takes about 5 minutes.
I usually replace my air filter every 2 years but I do not drive in a dusty environment. Well, they do throw tons of sand and salt on the roads in the winter. I'm conservative about maintenance, I would stick with the Acura filter.

 

Leaving out all the scientific explanations, I wanted to let you all know that after replacing my paper filter with a K&N, I noticed absolutely no difference in power or gas consumption. Now I have to clean the damn thing, instead of just throwing it out and replacing it.
