you can NOT feel 1hp difference in a car. and as stated above, and independant test showed a LOSS in hp with the k&n drop in filter.

you can deny and or try to make fun of my knowledge and or age, but a drop in filter will do practically nothing for power, the only advantage is being able to reuse it.

and if you honestly think a CAI or a SRI is a waste of money on an NA car, thats your .02, but if your gonna spend $40-50 on a filter, why not pay $150 more for a REAL improvement on hp/tq?

im not here to argue, just give input, and since i disagreed with yout drop in, you get mad. dont ask for input if your not ready to accept negative input as well as positive input

 

you guys are killing me with your pointless arguments! The truth about a drop in K&N is that hey do nothing other than the fact that they are re-usable. I work for toyota and the manufacturers plan way ahead for air reserve capacity in high load situations on their vehicles. There is nothing you can do to a stock car to make it take in more air than it already does other than putting in an intake. And as far as K&N drop ins go, they are just re-usable, but very bad for any car with a MAF or Hotwire air sensor cause overtime the oil from the cleaning kit out on the filter fouls them up. I know this cause I have done the test for hp gains and pros and cons as a final project in the toyota program that i am in.

 

haha..so you can NOt feel a 1 hp gain over baseline, but you CAN feel the 4-5 you get from a CAI??!! HIlarious stuff kid. you should write your own comedy.

you obviously are more interested in trying to show everyone how much (or little) you know as opposed to actually reading what i posted.

I have been driving my car for 30 thousand miles, 15k with my exhaust on. I know how my car felt stock. I know how my car felt after i put the exhaust on. I know how my car felt after i put the header on (and off). and I know how my car felt when i put the k&n filter in.

as i SAID previously, but you probably ignored because you're just so anxious to reply with some irrelevant post about how you know so much about engines, etc..

MY car already had an exhaust, swapping to the k&N filter even if it only opened up air flow a little bit, combined with my exhaust i probably squeezed one-two HP. Dude, you can gain/lose HP based on the viscosity and cleanliness of you motor oil (and I can feel a loss in power when i have dirty oil-if you can't its probably because you're an inexperienced kid who doesn't have a clue what he's doing under the hood or behind the wheel) and you can gain/lose power based on intake temps and air flow/restriction. Do YOU think you'd gain any HP by Removing the filter completely? well, let me tell you kid...You would. Probably more than you would get using your Magical CAI (which should stand for "Cooler Air Intake"-as many have already pointed out). so it stands to reason that you can gain power by reducing the surface area of your air filter and allowing for higher volume of air flow. Go talk to a real mechanic kid. theres a reason K&n is the most trusted and reputable air filter manufacturer in motorsports, and it ain't cuz the filter is resusable. iF you don't have one, then you don't know what you're talking about, you're just speculating. So just shut up.

btw, concerning that "independent" tc intake test...as others have pointed out in that thread, that was probably the most flawed experimental test i've ever heard of. That holds no water in MY book or anyone else who actually knows something about cars.

Sorry son. Just because you have $$$ to go out and buy parts for your car and have other people install them for you, that doesn't give you the right to go around acting like you're some kind of pro.

the bottom line is, the people who actually HAVE the k&n, like it, and gave their honest opinions on it. YOU do not have it, and therefore should not even have gotten involved in this thread.

 

ON TOPIC here!

The K&N drop in filter does not give horse power!
It acctually reduces it by 1 or 2.. so I dont know what you people are talking about.
The good thing about it is it replaces it with a nice start, with torque.(sp)

Here is the thread with the dyno..
READ THE PART WITH DROP IN FILTER. woot laters.

Had a friend conduct an unbiased test. He swapped the air filter for a K&N and had another friend drive it, before and after, not knowing what the nature of the mod was. The third friend's conclusion:

"Did you do something with the suspension? It definitely feels tighter I think."


Anyways, a K&N will NOT cause a lost in power. A dyno can very easily have a difference of up to 5%, usually around 3%, but in whatever case, a gain or loss of 1 hp is NOT significant in ANY right. A 5 hp gain/loss... I still wouldn't trust but I'm going to say that a 1 hp difference is negligible.

The % error could happen on the same exact car on the same dyno at the same time and conditions. I would really only take a 10 hp increase/loss as anything approaching significant. Unfortunately, with bolt-ons, gains rarely exceed 10 hp on the tC so a consistent +5ish hp seems reasonable to me.

 

I say its great for the price and somewhat keeping the car stock. I didnt know about the 5% thing but if it does lose like 1hp, it makes it up with the torque increase. Its not a lot, but its something. Im happy with it and will not change it. woot. Go K&N.

 

you can keep throwing insults about my age, since it seems as if they is all you know how to do. age has nothing to do with knowledge about the 2azfe, and aftermarket parts for it. you can sit on ur chair and tell me you can feel 1-2hp gain/loss all you want, but im telling you right now that if u drove a tC with 140whp, and then drove one with 141whp, you WOULD NOT feel a difference, its all in your head. And as for feeling a difference with my SRI, yes I can. But then again, with a SRI and full exhaust combined, there will be a difference. Once I hit 3k rmps, I fell the power gain, not much, but it is felt. Having an exhaust with a factory air box (reguardless of the filter) is not going to make a noticle differnce from the TRD filter, paper filter, or k&n drop in.

I really dont care how long you have been driving your car, my mom has been driving since she was 17, so thats about 25 years or so, but she dont know a lick about cars, so why do i care that you have been driving your tC for 30k?

all im saying is be open to what others have to say, dont fight back just because others (like myself) feel you made a bad investment. you can debate the point, but there is not need for all the personal attacks.

 

omg... "knowledge about the 2az"?!!! what do you think it is a B SERIES??? its a toyota camry 4 cylinder motor!!! THeres only been aftermarket parts out for it for barely 2 years!! SO i guess YOU at 20 years old are the FOremost afficianado on the 2AZ?!!! YOu crack me up kid! I NOTICED A DIFFERENCE WHEN I PUT MY K&N DROP-IN IN. I DIDN'T DYNO IT, BUT I ESTIMATED ABOUT 1-2 HP PICKUP WITH MY EXHAUST. I should clarify, i didn't really feel a difference at the wheels, but in the motor (revs, tone). YOU HAVE NEVER DRIVEN MY CAR, NOR HAVE YOU DRIVEN A CAR WITH A K&N...YOU HAVE NO CLUE!


KID-i've been working on supras, dsms, vtecs, and more for the last 5 years (before you were legally able to DRIVE!) K&N has been making performace air filters since before you were born. I think i'd trust my first hand experience and K&N's reputation over your speculation

DO YOU EVEN KNOW WHAT HP IS? Go tie a rope around your ankles and have 1 HORse pull you around the farm. Then tie ONE ankle to 2 separate horses, and have them pull you around the farm. YOU'LL FEEL A DIFFERENCE!!!

Did you just reference your MOM?? YOU really don't get it do you. My point was the after driving the tc with stock air filter for 30K miles, i know how my motor performed. ANd i was certainly able to notice a difference with the K&N.

I'm TOTALLY satisfied with my $30 investment. Seems like you're a bit jealous that you spend $200 for a ricy noisemaker. But maybe not, cuz you seem like a FastnFurious Ricer kid anyway. In fact, your car is rice. all the lites and gauges, engine dress up, diamond plate, vinyl and carbon fiber. You'd get laughed out of TOWN if you came into our shop. AND Its an AUTOMATIC!! Ha! how funny that the 2AZ afficionado can't even drive stick?!!!!

Just because you: a) get money from your parents b)wait tables and spend all your money on your car while you live at home ...and put all your $$ into your car, doesn't mean you know anything about what you're talking about. I'd much rather have a K&N drop in than a Weapon R intake (noisemaker) (chintziest company on the market). Do yourself a favor, since i just owned you, stick to threads you know something about, like "HOW to RICE out Your tc".

 

we call that an ___ dyno.....its being able to tell the difference in power.

DO YOU EVEN KNOW WHAT HP IS? Go tie a rope around your ankles and have 1 HORse pull you around the farm. Then tie ONE ankle to 2 separate horses, and have them pull you around the farm. YOU'LL FEEL A DIFFERENCE!!!

priceless comment, and yes i can feel a difference, its not a huge difference but its noticable.
too bad i did not dyno just the filter when my car was stock.

 

did go guys get it from the k& n website, im pretty much sold on this.

 

i got mine from martelbrothers.com

 

there is a silencer on the stock intake? where?

 

right up front on the tube to the left of the MAF sensor, it looks like a box sticking out of it.

 

I was thinking of using the drop-in but certainly not for power gains. Fact is, a $30 part is not going to increase hardly anything, let alone raw power. The lawnmower analagy doesn't work anyway. 4hp to 6hp is a 50% hp increase, whereas 160 to 162hp is less than 1% (in the tC for example).

 

^^^ Now a 2hp difference on my 9hp 150cc scooter would make quite a difference

 

so this sliencer can be taken out? will removing it cause any damage?

 

you can remove the silencer portion, but you'll need to plug up the open end thats left exposed afterward. I've been contemplating what i could use to block it off. maybe a large bolt or something. Has to be something sturdy though (not tape or something) because that vacuum suction will pull whatever it is rite thru into your intake manifold!!

 

so to the people that has teh sliencer off, what did u use to block it off?

 

2lotc you need to chill out man. Break_away is always providing great information to these boards so there is no reason to flame him over something like this.

The fact is the K&N will be a better filter than stock, but you are not going to notice the HP gains from it. If you say that you do its all in your head. Also when you're talking about 1-2HP from a filter you probably wont see it on the dyno either.

If you have the money for the filter and do not plan to get any form of SRI or CAI then I would say go ahead and get it. K&N does make great filters and as I said it would be better than the stock filter.

 

shove an old sock in there, it will do the trick........
