It actually a Volant intake, but they are all the same.

Problem :



Time to chane to vararam ? I red somwhere on this forum about KN damaging engines slowly, there was a lot of greese with dirt stuck to the blat. I assume that more came through.

Any opinions on this one ? oh and i have the big inductiun tunnel with it.

 

Prepare yourself for a lot of reading on this topic. It gets asked/replied to in hundreds of past discussions.
In C5 Tech, click on search this forum (in the red banner), using keywords "K&N filter".
Some anti K&N filter members will suggest using an oem paper filter only. The real issue is that most owners tend to over oil their oil gauze filter media which leads to MAF contamination. Many owners also install an oil gauze filter system and ignore routine filter maintenance. They're not designed to go for thousands of miles w/o cleaning and re-application of oil.
It's your car to do with as you please.
If you intend to use any after market CAI ("cold air intake" or "cool air intake") system, you'll be using an oil gauze air filter media of some manufacture. All of the most popular after market systems use them, including VARARAM. K&N, S&B, DONALDSON/SLP "Blackwing", GREEN and other oil gauze filter media manufacturers supply filters for many CAI systems.
The image that you posted is more than likely not from the air filter, but from oil ingestion from the oem PCV system or a combination of both issues. Your air intake systems clamped connections may be allowing ingestion of dust into the air flow path. Clean your engine compartment. A greasy engine compartment is a magnet for dust and contaminants.
You can reduce/eliminate the intake/throttle body oil contamination with proper maintenance of the PCV system and/or a "catch can" available in many configurations and from many sources. Several of the site supporting vendors carry them. You can DIY with a (CAMPBELL HAUSFIELD) air compressor filter if that's how you elect to handle the issue.
You can research the "catch can" modification in the same forum, using those keywords.

 

Hi felga -

I have had a oiled-gauze (K&N style) filter on my Z06 (Halltech TRAP system to be specific) for 50k miles now, and I will assure you that my TB is sparkling clean inside -

The image you posted here is indicative of a malfunctioning air cleaner - regardless of what type of filter it was.

All of the air has to pass through a filter element - that picture does not look like that was happening, or the filter was not properly oiled etc.

best regards -

I have used K&N for 4 years, my TB looks clean as the day it was put in.

Wonder if there was too much oil put on the oil paper?

 

I have used K+N filters for many years in all my cars, first time I seen this.

Maybe you need to install a Catch Can?

 

Thx for answers, i`ll install this catch can anyway looks like good thing for the engine. Maybe I overoiled it ,i used whole spray for 2 cones , but i thing that cones aren`t to good quality it` just KN lookalike. I want vararam and i`ll buy paper filter for it. Is there that mutch difference in performance increase or KN and other are similar to vararam.
I don`t want to go towards that subject now but it looks like vararam construction is the only proper cold air induction .

OK You over oiled it.

Personally I never oil mine. Just blow the dirt off them and put it back on.

 

V-ram is matter of opinion. I have taken off many v-rams to help cars breath better and run cleaner and get a bit more power.

 

If I understand this statement correctly, you used an entire aerosol can to re-oil the two filters? I hope the cans were almost empty of product.
If so, that's way to much! Oil sparingly over a clean, dry gauze filter. Allow the oil to wick over the pleats over time before re-installation or starting the engine.
The CALLAWAY "Honker" and SLP "Blackwing" with an enclosure and open shroud are also considered true CAI ("cold air" or "cooler air") intake systems.

 

I think the oil is used to keep the water/vapors out if it's raining.

 

I think the oil is to trap smaller particulates before they enter the air intake...keeping water/vapor out might be a benefit as well.

 

The whole motor looks dirty, We need more pics

A 12oz can of oil should last for years.

 

Tomorrow mister

And don`t break me down FIrst You start topic about garages bigger than my house , then You have flat,clean beautyfull roads and now You`re telling me that my motor is DIRTY

Ok , just kidding, i bought the car form US soldier , in 1998 the car was sold new in belgium, and then in 2002 bought by this soldier and since them he covered 500miles in UK!!But the car was kept in hangar with all the apache helicopters , so a lot of greasy there , a lot of fuel , jet engine and humitity inside. That`s why the whole underbonet is rusty a bit and just dirty.

I`m doing my best to get her tiptop, but it`s not easy in this country, i should move to US instead UK

I used whole 120ml (as far as i remember) bottle of spray cuz instructions said so.

Thanks
ANdrew

 

Thats so they can sell you more...lol

 

Ok. I found this bottle and it`s half full/empty .

Because it`s raining and I don`t want to be a b...ch . I took TB and ported / paited it. I`ll fitt it tomorrow and post more photos.

 

That kind of looks like blowby, to me. Have you check your PCV system? You might want to get a catch can. IMHO

 

I noticed at the Detroit auto show many brand new cars have K&N type filters on them. So maybe those who feel they are bad for an engine are wrong?

 

I can't think of one OEM that uses an oiled gauze filter. What they do for the auto show may be another matter.
I've used K&N as well as paper on a variety of vehicles, and paper definitely keeps things cleaner.
It's been said before, but hold a K&N up to the light and observe all the spots where there is no filter media. Does dust going through those areas take a magical detour over to a spot with media?

True, the area with holes is small, but it's also the area with least flow resistance, so a disproportionate amount of air will come through these holes.

 

I'm callin' the SPCA...

There isn't an after market air intake system that doesn't use an oil gauze filter, either. So, what does that suggest?
Maybe people shouldn't blame the oil gauze filter, but the owner who over oils his...

 

The oil on the gauze is what makes it work ... without oil you are letting dirt get by.
