Thinkin bout a cone filter

[lyates1987]

I've had a new cone air filter sitting around for a lil bit and was wondering if this is a good idea to add to my stock 1.8. What do yall think?

[hgtuner08]

people will tell you that cone filters or pretty much anything outside of stock filter replacement or APR intake will raise your IATs. If you don't really care about that then go for it.

[hgtuner08]

Personally I would throw a high flow filter in the stock airbox, keep air scoop, call it a day.

B6 stock airbox is perfect for even a 300hp tuned car, we're lucky with the stock airbox. I would suggest a K&N high flow airfilter for $50, washable, You never have to change it, but don't expect a back braking difference from a regular filter. Cone filter would be a pain in the ass to maintain compare to this one, and You have no need for it.

I have heard even the stock filter is better then the K&N high flow because of the oils

[Waspjr]

The cone will sound better and yes will not have the best iat and any k&n or serviceable filter will put oil mist on your maf. That being said, i think the plastic stock air box is cheesy altho might have better heat insulating characteristics i run a cone filter and was working on a custom aluminum airbox but am now going 2.7 swap. So do what you want really but remember if your on the dyno put the plastic back on lol

The oils can cause problems with the MAF, more often than not it is due to over oiling by the individual after cleaning the filter.

The oils can cause problems with the MAF, more often than not it is due to over oiling by the individual after cleaning the filter.

Over-oiling, oiling the wrong or both sides of the filter, and/or not allowing it to dry completely is what damages the MAF sensors. A cone filter will hurt your performance, MPG, and over all smoothness of the engine, but will add a bit of a BOVish psshh noise.

[lyates1987]

Well minds made up, I sticking with the stock setup and getting a better air filter. Thanks for the input guys!!! I was looking at a K&N to replace the current one. I haven't even looked at the current one since I got the car but judging by the last owner I bet it needs replacing. This Helped!

I believe this is true. I've had K&N filters in both B6s and never had problem with the MAF.

dry flow filter > any overpriced oil based filter.

if you have stock air box, just put a dry flow filter in it.
i wouldnt use a cone filter unless you plan on making a true cold air intake. otherwise you're sucking hot air from your engine and turbo into the intake.
most people dont run a CAI unless they are big turbo and mounted up top (because there is no other option really)

Any proof to back that?

[Charles.waite]

Just get a stock Mann filter and call it a day. The stock turbo is going to pull as much air as it needs through the oem filter. "upgrading" it isn't going to amount to much. You're better off socking that $50 away and saving up for a tune or some TT injectors and a Big injector tune

Or a good case of beer!

This. I have an aFe Dry Flow (which costs about the same as a K&N) and I just wash it with water every other oil change and let it air dry.

Any proof to back that?

They probably perform similarly but with a dry flow you don't need to worry about all of the problems with oiling incorrectly or even buying oil.

washable dry and flows better than stock

[Charles.waite]

"Flows better". Maybe, under certain conditions. But stock is more than sufficient for the airflow needs of a stock turbo.

It's perfectly alright to say you want a fancy filter even though it provides no tangible benefit. Some people just choose to spend their money elsewhere.

do i need proof?
pretty much everyone advises against oil based filters. due to maf contamination, contamination of your piping, etc..

[Spike00513]

Of course ECS's site says the AFE flows better...

Do you expect them to try and sell it by saying "This $50 air filter is absolutely no different from a $10 Mann Filter"

I think the air filter is plenty big enough already, and PhD Audi engineers know what they're doing. Not only with filter element size, but with the design of the intake system. Whether it be the length, the shape, or the helmholtz resonator that 3.0's have on the back (not sure about 1.8T).

Wasting $50 on an "intake" is not going to turn the car into a Ferrari. It will make no difference.

It does make the annoying sound of air induction, which ricer children enjoy. I personally prefer the sound of an engine, music, exhaust, and so on. Not the sound of air being sucked through a straw, coming from my engine bay. I find it easier to drive the car when I hear the engine too. You know what the car is doing that way, and looking at the RPM gauge isn't so important.

Replace the $10 filter whenever you're supposed to, maybe blow dirt off it with compressed air every once in a while, make sure your self-tapping airbox screws haven't stripped the plastic, and clean your MAF. Maybe clean the airbox too. Mine had a few handfuls of sand pooled up at the bottom, along with about 20 cigarette butts.

Every detailed review and comparison of K&N I have ever read comes to the same conclusion. K&N = Junk

[ECS Tuning-Audi]

Different materials breath better than others. That's pretty obvious. A paper filter that's great for filtering out fine particles will not out flow a much more breathable material like gauze (which many aftermarket filters are made out of). Will it filter the air as well as the paper? That's debatable, which is why some companies have introduced oiling which will help get back the loss in filtration. Every option has some positives and negatives. That's the nature of modifying your vehicle. If there was a single product that worked as well as the OEM but had mad gains everyone would want it. Maybe in a perfect world..

Pcv?

My buddy owns and tunes cars for a living. Grabted, he owns a Honda shop, but he does get some fast cars. Recently dyno tuned a 404awhp civic that gained 30whp by taking off the 4" cone filter directly off the turbo. Just food for thought.

Was it running a K03 turbo?

this.

which is also why audi engineers don't use oiled filters.

No, a precision 6262. Pushing 18psi.

Ding Ding Ding!!!! Winner winner Chicken dinner!!

Unless you are pushing some really big HP numbers a plain 'ol stock paper filter changed at routine intervals should be sufficient.

[Charles.waite]

See in that case, airflow requirements will likely exceed a stock-type filter (or even a high flow filter). But for a stock turbo engine, you'll never exceed the airflow limits of the OEM filter.

[viceprp]

It was only an example. Take it however you like, in the end the cone filter will only hinder.

So they did a 4WD CRV drivetrain?

[viceprp]

Sorry my phone auto corrected for awhp. Fwhp is what I meant to say. He also tunes many other variety of makes but is well known for Hondas. He will be fabricating my fmic plumbing and catch can. You will literally shit bricks over his welds and what my catch can will look like.
