Air Filter which is better? Options

[Box]

Yes i think about K&N panel filter but i will not have any change with the sound of the engine right?

No. If you want sound go with a true cold air that puts the filter into the fender. The short ram intakes that have the filter exposed in the engine bay actually provide no gain, if not hurt performance.

Completely false. They tested this and it makes no difference where the filter is, not a noticeable one anyway. What really matters is the intake piping being a direct line into the throttlebody instead of having sections of dead and turbulent air due to stock baffling and "water protection" boxes.

Ideally, the best setup is the stock air box with a high flow air filter and intake piping off of it into the throttlebody. Our Celica's take air from the front bumper and route it through the driver fender into a intake hole up to the air filter. I have my filter positioned right behind that intake hole/plastic air route piping and it does fine.

They never did a test with a TRUE COLD AIR INTAKE. They did stock, SRI, no filter, SRI with no headlight, then covered SRI, and finally their Jerry-rigged setup which actually provided a gain and would be closest to a true cold air. Plus what about my statement is false? I said SRI loses power, which you backed up with the video you posted.

Besides the fact they tested on a turbo car.
A lot more likely to get gains on N/A engine

That posted video is just for Cold air Intakes; McM also did another video on different types of POD filters on a N/A and Turbo car.
The N/A Car lost 3Kw or so and the Turbo gained 3-4Kw...
If the OP is just looking for sound then the performance doesn't matter too much... It depends what they want; the roar of a RAM or the purr of the CAI...
They also looked at a Oil Panel filter (which can eventually damage the car) which also provided no gains.

But, one thing I will pick on the video; they did not tune the car after the install (Much like 90% of the people I know that add these), so basically it is still unconfirmed

We know ram air is good for adding power, so make one of those for the car.

I saw a filter comparison somewhere where a couple of filters were tested against each other in a filtering and airflow test. Mushroom filters came out best flowing because the ones they used were designed with a velocity stack integrated into them which helps flow massively.

Cone filters the K&N was the best in terms of filtering but required maintenance (cleaning and re-oiling) to keep its filtering ability up its best. AEM Dryflow filtered less but requires less maintenance (just clean with water) and flowed a little better too iirc.

Apexi filter was the best, I think it filtered better than the K&N and flowed better too, but was really more expensive than any other filter. I think the other filter they used was the HKS mushroom.

For selecting a correct filter, this is right on for air flow. Realistically, the K&N, AEM, Injen, Weapon R, Spectre filters are all the same when it comes to oiled filters. So don't waste your money on the high end ones. Mushroom filters are most likely to allow dirt through, and you might as well use a stocking, and Dry Flow's seem to work well...

Realistically though, you're not going to notice that much of a difference between them. So pick one you think looks and sounds cool and go with it.

The video was very interesting. . .I am a little bit confused now,i dont want to put a filter and lose power instead of gain. . .:-) can you take photo to see where you put it exactly and how?

I will probably use a pipe like one you can see in the link to get the cold air from outside to the filter,i think it will help it. . :-)

What I was planning on doing was run it to where the filter was inside the fender, then run flexible tubing from in front of the filter to the front of the car to bring in fresh air. Hence emulating the factory setup, but hopefully a little better and of course louder.

I was actually going to do this too but in order to do this you'll need to make an intake box because those will deteriorate over time and you wouldn't want the engine to suck in any of those stuff. So you'll need some kind of air filter between that and the Throttle Body. Too much work. That's why I didn't go with this method.
