That was then. This is now. Different world..
Only getting 17mpg

Older charger I mean a 2012 model that I got brand new and kept until 2023 and put about 140000 miles.
Either way I no spokesperson for the brand and have zero reasons to defend it.
I just used for a very extended period of time with absolute zero problems, not only that but with mild performance and MPG gains.
Have you used it for an extend period of time and had problems ?

That’s great that it worked for you. It’s well documented that they are problematic. There are alot of people who have used K&N filters and had problems. If you google “K&N problems”. You will find several different forums for different vehicles with the same stories over and over. Usually mass air flow sensors get residual filter oil on them and then need to be cleaned or replaced. Faulty readings caused CELs. In my case I bought a brand new 2002 VW GTI and heavily modified it. It had the VR6 so I installed a VF engineering stage 3 vortex centrifugal supercharger. The problem I ran into was that I had constant problems with my air/fuel ratio because of the oil from the filter constantly coated the MAF. At that time VW had a special tool that was not available to the public that fastened the actual sensor to the housing. The only way to properly clean it was to remove the sensor from the housing. I would remove the housing and try to clean it with a spray cleaner while in the housing, but it would sometimes damage the sensor. It cost nearly $300 to replace every time because they would only sell it with the housing together. I tried using less and less oil, but then started hearing from other VW and Audi tuners that under oiled filters allowed too many particles that would damage the internals. I was told that kind of damage would not be noticed for a long time. So I just kept replacing MAFs at $300 with every oil change at 3k mile intervals. I ended up selling it with less than 30k miles on it so I don’t know what happened to it. My story was not uncommon. Many guys switched to other filters I think called AWE or something like that. They were oil free. I didn’t feel confident that they filtered well enough being oil free. For vehicles that are heavily modified or very powerful it is necessary to have more flow, I get it with your hemi it benefited from your K&N. For most daily drivers the benefits are not worth the risk and headaches. For weekend or race cars yes it’s worth it. Now with so many electronics and technology our engines are different and more expensive. Mt GTI VR6 fully optioned was 24k new. Our LCs more expensive $65k, more expensive to repair and I wouldn’t want to risk voiding a warranty for a few hp or mpg gains. I definitely don’t want poor filtration to damage my internals and have problems later from being under oiled.

K&N has been around for many decades, and for many years has provided 10-year/million mile warranties to anyone that can prove their products have caused engine damage. I had one completely refunded by them that was throwing MAF sensor errors. However, this topic has been argued over the internet endlessly and will never be resolved. TRD will offer high flow air filters for those that can't trust K&N or other aftermarket vendor's engineering/R&D.
Yikes
Yeah, I had in most of my cars (and still have my other two) which at this time I have a combined mileage of 400k miles on those filters without a single problem. Only mild mpg and hp gains which is more than enough for the intended purpose.
Granted all were NA (V8 Hemi) and a Subaru outback (2.5 boxer NA) with nearly 200k miles on the clock.
My best guess is the forced induction sucks the oil off the filter causing problems.
But back to the MPG topic, curious if the "TRD Filter" would make any difference...
My apologies for getting off topic. 
Cheers my friends

Cheers my friends .The genuine TRD air filter part number is
PTR03-35240
It's washable/reusable and has a similar design to...other aftermarket air filters
Probably can't hurt or void any warranties if its a genuine Toyota part, no?
Impressive similar design I would add...The genuine TRD air filter part number is

But if my experience is any good with the other filter, I wouldn't expect any improvements.
I'm a Realtor so I do a lot of shorter trips, showing homes. Once I get a day off and get on the highway the mileage always jumps. I'm averaging 20mpg right now. Much higher on the highway if I can keep it around 65...big if.
I just bought an LCLC (our second) in Peoria, AZ and drove it back to Denver, CO. Except for one 175 mile stretch (Mesa to Holbrook), we kept on 75 mph interstates with the cruise control set at 80 mph. Using premium gas we averaged 20.6 mpgs for the first 630 miles (day 1) and 20.1 mpgs for the last 250 miles (day 2). Roads were mostly clear and dry, not a lot of traffic slowdowns (a little in ABQ and CO Spgs), mild winds, about 35 to 45 degrees ambient temp.
I've been getting 23.1 mpg regularly on my day trips up to the mountians to go fly fishing. It'll be interesting to see if this new LC does as well as my first LC.

This filter does not fit. Couple of us have tried it. No go.The genuine TRD air filter part number is

I think it has already been answered, but my experience with K&N was short lived… one oil change interval in my 2006 Avalanche. I sent another oil sample to Blackstone after using it for 6,000 miles, and the amount of silicates and other crap that was in the oil was scary. Switched back to a OEM and the problem resolved by the next oil change. The best explanation that I could get from the K&N company after presenting them the facts of the oil analysis,… “Look, we are a family owned and run company, and employ xyz employees”. But he would not address any of my concerns brought up by the oil analysis.
SMDH.
Forgot to mention that on a 43 mile stretch, between Heber AZ and Holbrook AZ, our brand-new LC got 27.2 mpgs. It's a two-lane stretch that's 60 - 65 mph .
Why the great gas mileage? I suspect it is because the elevation changes from 6,600' to about 5,100'. Over 43 miles, that elevation change is imperceptable. But it goes to show that gas mileage is greatly affected by relatively small factors.

Some updated numbers.
Stuff that affects my mpg.
It has been windy some days. I have been driving a lot of back roads in WNC and east TN. Roads like tail of the dragon (which sucks in a lc btw ). I also use a high hths oil so slight parasitic loss there.

No15, that's the kind of information I keep! I'll admit that yours is a bit more detailed, though.
My father used to keep a gas/mileage log in his cars and I've been doing that since I got my first car. I'm glad to see I'm not the only one.

I tried an experiment today: interstate driving at 75mpg, mostly flat-ish or rolling hills, cruise control. First half in Eco mode, second half in normal mode. Normal was 0.8 mpg more efficient when I took this picture (18.4 vs 19.2), ending at 20.1 mpg when we got to our destination but there was a little lower speed local highway driving by the time we got there. It’s only two datapoints and I could be overlooking systematic errors, but I’m now skeptical about the effectiveness of eco mode.
Same tires 275:60R20 and getting 17-18. I assume the biggesr circumstance of the tires affects the calculation? I need my college kids to do some math for me since apparently they now know everything…lol.
Geez I really need to spell check….
At least the auto correct didn't use the other "circums...." word.
