K&N Air Filter Review - Debunking the Myths (and why OEM is better)
 

http://www.nicoclub.com/archives/kn-vs-oem-filter.html
Have we been wasting our $$$...... Some interesting data here.

Interesting, but the data isn't specific to our vehicles with dynograph proof and such the tests refer heavily to diesel vehicles and their filters, although similiar in design, they are most likely not accurate to our cars or a good comparison to our cars. With our cars ft86speedfactory did some good dynograph tests when the vehicle came out which can be seen here:

It can also be corroborated with grimmspeeds results here:

Both of which picked up around 4-5 whp, as to whether or not those stay in the long term after months of use and k&n recharges and filter changes remains to be seen. Also as to the other stuff they tested (i.e flow, filtering efficiency, dirt passed etc.) we can't know for sure for these cars because those filters haven't had such a thorough testing as the ones made for duramax diesel intakes.

hey, check this chanel, here's all the answers

Cool, thanks for reviving a 3 year old thread.

would you prefer that he posts a new thread?

Or how about not post at all on a topic that has already been covered in depth?

Or, how about believing what a shop that sells aftermarket parts tells you.

For real, and if he starts a new thread people will say this was beat to death already yadda yadda.

The guy has something to add, that's cool with me. Idk why some have to be such ****s about it.

This is why there is more activity on the ft86 reddit forum than this one now.

there's an xkcd for that:

look, if you already know it, you need to teach us, which you're not doing. if you have such an expanse of knowledge that you already know it all, there is no need for a searchable repository like this forum, and you can stay on facebook with all the other brilliant here-and-now people.

the rest of us are here to interact with each other, and learn, even if that learning means reviving something that was created a while ago.

I think its time for the annual update. Not to waste your time off-topic, can you please tell me which filter I should use in my 2013 FRS?

Im pretty sure you know what might be best for my car based on your extreme knowledge of filter coverage on the forum. So I trust your opinion, and I'd like to know what I should use. I was leaning towards a washable dry drop-in, because I might be too lazy to oil it. If possible, I'd like to stay under $50 and have a re-usable filter, but if you think I should spend over that I'd be keen to understand why.

Thanks for coming back to us! :)

the overall consensus is that there's no major gains to be had with the filter alone. very minor gains with changing the intake.

if your concern is maintenance, stick with the stock filter.

Thank you for the update. Im also putting in the Perrin inlet tube to give some better air flow. I have some kinda exhaust as its loud af, but being a secondary owner with little-to-no car knowledge, it's a bit daunting for understanding what's best for the car.

Basically what soundman said, but I personally use a Perrin inlet tube and a K&N air filter in my car. If you really want something aftermarket you can get the HKS, Blitz, Apex'i, or Grimmspeed all which are dry filters that come to mind. This maybe subjective, but when i got the Perrin inlet tube and K&N filter i thought the car revv'd much easier too but i have no way to prove this. Hopefully this was helpful and makes it easier for you to make a decision.

Thank you for the info! Would that be the oiled K&N filter?

And yes, it is very helpful! Ive read far too many forum posts and websites on the subject, but hearing about the high air-flow filters also causing future issues with letting in more dust etc is a bit concerning. I guess the oil would help trap some of those, but then the risk of over-oiling could cause issues with the MAF too. It's all very convoluted and there is really only personal choice in the end. Having another driver's experience (or multiple in this case) is very insightful on what works and what doesnt.

The dyno runs on the cars is a bit over my head in most aspects, and seeing the minimal gains doesnt really say much for the performance when actually driving it. Hearig that it "feels" improved is a good enough judgement for me.

I do also appreciate your sincerity in answering the question(s). The search bar doesn't work on my phone browsers, and finding this thread was the most relative I could with the advanced search. It seems finding specific items here isn't an easy task haha. Thanks again!
