K&N drop in air filters..............will you?
 

I see they are available on their site. $43.00 Will you?
Thoughts?

I was about to when I figured out which one fit (33-2252 btw). But thinking about it, the MAF is so close to the filter media that I worried about oil getting on it.

Didn't even think about that. Will you think about High-Flow Air Filter?

If you properly clean and oil the filter, you'll never have that issue. I've used oiled and oil-less filters on everything from vintage motorcycles to brand new cars and never had any issue. Also, K&N is very adamant that their products don't cause issues. Check the links for more info! K&N is my 1st choice in air filters on my personal cars and motorcycles.

I was thinking about it, funny how Amazon says 33-2252 will not fit when you put in the 2013 Scion FR-S (just outdated page I'm sure).

So should I buy the K&N drop ins or are they a waste of $$$

Thats the question... Not sure if anyone knows yet.
Typically, drop in filters make power, but on cars like this- its often 5HP or less...

Right now the only dyno figures I have seen are on prototype replacement intake 'systems'

I like ITG filters. The 3 layers foam has good filtering capacity (still inferior to the stock paper filters) and it doesn't need oil.
On 200-300 hp cars a panel filter can be good for up to 3-4 hp...I'm talking about max power.

I change it only because I save up on the servicing.

You can also use a TRD PTR43-00085 the FR-S uses the same 17801-0D020
filter as an 03-08 corolla and a 1st gen TC

I just got the 33-2252 k&n. And it sounds different .... I like

Where did you buy it from? Online? Or local?

It's the same as the scion tc 1gen

Got it at autozone. 51$

I have the TRD filter in my fr-s. worth the $49 I spent.

didnt someone remove the air filter and say the car made no extra power? if thats the case i doubt any filter will make a difference. the only benefit of a k&n is never having to replace it.

I had a k+n in a mustang for 70k miles and the engine light came on since the day I installed it.

Where did you buy that from?

I forgot to put the stock filter back in when I dynoed our car.

This dyno was with a K&N drop in.

Ishii

If you look at the waves of the stock filter and the waves of the k&n


The k&n is tighter ....means that there is more surface area = more flow

For now that may not matter but with exhaust and other addon it will make .0000001 sec difference lol

I have ordered a K&N drop in filter, but I would love to see a dyno if it gives you any extra at all.

I wouldn't get just a drop in-- i'd get a short ram or something. Just a drop in wouldn't get you much power, but would likely give a bit better response, MPG and sound. I would love to get a heat-wrapped full intake though.

Are you guys seriously thinking that a drop in filter will add any noticeable power??? :bonk: A drop in filter isn't increasing the amount of air sucked into the intake enough to actually help the performance of the engine. IMO K&Ns are just a waste of money I mean sure they last "forever" but you still have to clean and oil them. I'd much rather just pay the $50 for a brand new filter every 10k miles or so..

If you really want to add performance through an intake system just get a CAI or SRI even then I doubt those will add much a noticeable difference alone. Full bolt ons and a tune would be the only real way to get a nice performance increase that would be noticeable.

Anyone dyno'd a TRD filter in the FR-S yet? their may be a thread but I can't find it.

No not crazy not expecting any power increase but since the TRD drop in will cost me about $50 and it's reusable I think it will tide me over until a decent CAI comes out

I think I will definatly do a cold air intake.

Ordered the 33-3252 because it's the only stock legal intake mod allowed in SCCA

By increasing flow, which some drop-in filters do, it will increase engine efficiency and power. Will it be enough to notice? Probably not, but it will still exist. And not all CAI's increase power. Most are nothing more than cosmetic items where a drop-in filter replacement would have done a better job.

All that said, I agree with your last statement that you won't really notice any real power gains without installing decent parts and tuning for your parts and your car specifically.

As for re-oiling and all that nonsense, just buy another high end filter and throw the old one away. The re-oil kit is going to cost you about $15 to $20 already. Then add in your time to do it. And, if it's your only filter, you shouldn't drive without it in the car, so you'll have to wait while it dries and is ready for re-installation. Time alone, it is not worth it for me.

I will probably buy the TRD filter as the K&N's do come with a little too much oil for my liking. However, if the oil is fowling the MAF, just take it out and spray some electronics cleaner to fix the problem when you switch back to a better filter.

If you're planning on keeping the factory airbox for the life of the vehicle, a K&N and a filter cleaning kit can save you some money over buying paper filters every 15k miles. I'd wait until 15k when the stock one is dirty and then swap over. I doubt it'll pick up much if any extra power but not having to piss through $30ish every 15k on a paper filter ain't a bad idea. If you plan on getting an aftermarket intake, I woundn't bother.

The correct part number is 33-2300. Same as 05-06 TC. I just checked K&Ns website.

A lot of people have been saying 33-2252 but thats incorrect. Just ordered mine off Amazon for $37+ shipping!

Confirmed in Toyota's ordering system as well: TC & FR-S ... Same part number.
Thanks Adam at Stamford Toyota :)

My 332252 works great sorry to tell ya:thumbup:

Mine too. I don't think the 2mm difference in height will make any noticeable difference

Lol ok as long as everyone's cars are breathing right. Just passing on what I found. I had no intentions of sounding smug my bad :)

This

TRD air filters = K&N air filters.

You know for a fact that the TRD air filters are simply rebadged K&N filters? Or are you just guessing?

I have personally used and seen both TRD and K&N filters on the same vehicle. And the filters are definitely different.

Not always, aFe has also made some TRD stuff for the Tacoma. The aftermarket bids on TRD jobs and they use multiple vendors.

The TRD one looks very, very similar to the K&N one. If anything, I love how the TRD one has a red outline around it, matches Firestorm very well! And yes, you can see it slightly around where the airbox closes up.

I don't doubt several vendors have provided air filters in the past, but to the best of my knowledge all the more recent TRD air filters (standalone and the ones for their intakes) have been manufactured by K&N.

Keith is correct, I can confirm that above about aFe / TRD ^

A little tech info for you guys...
Funny thing those AFM (air flow meters)... sometimes a filter can improve performance on those cars vs. no filter. You must be asking- How?

There is a difference: Eliminating restriction of the filter vs. no filter isn't complete / relevant data... We must look further.

On some cars, those with AFM especially close to the filter element, removing the filter, changing the way the air moves over the sensor element can cause turbulence over the sensor- and cause problems when it sends this erroneous data to the ECU.
Perrin Jeff posted up some very nice information on this phenomenon in their Intake Thread, thats a good read for those not frillier with intakes on late model cars.

Now I do not know for a fact that this happens on the FT86, perhaps only the few that have back-to-back dyno'ed the cars and data logged do... Jeff might be able to pop in and tell us that this phenomenon was observed, or that it was in fact not relevant in this case and the stock OE filter element was just that good.
Perrin are also using a Dynopack dyno (One of my favorites for this type of work). These are extremely accurate and would be very good to show some gains, even if in the 3-5 WHP variety as they are very sensitive if they are used under closely controlled conditions.
