Cone Filters and airflo meters

[Eckard]

Hey guys

Hope all is well with everyone.

Question... What is the story with so many people complaining about cones or aftermarket air filters stuffing up airflo meters? Oil on the platinum "rods" compromising readings and ill long term effect?

Anyone got some clarity on this as to how much truth there is to this matter?

I've had a k&n appollo on my car, sounds awsome. After cleaning my airflo meter and putting my stock box back it seems that the car might perform better. My power feels like it's coming in earlier. Is this a subconscious feeling?

I am dying to put my cone back for the louder turbo spool sound but I don't want to compromise anything.

Will do a dyno end of the month with std and cone to see whats going on.

Hi

Cone filters work well if they are fitted low in the engine bay but suck in hot air, panel filters stay cleaner but have less noise .

You don't have to worry about the oil in K&N style filters hurting your maf element as long as you let the oil dry properly before reinstalling the filter.

It takes a good 45 minutes to dry properly which is the step most people miss.

A true cold air intake will draw air from the outside of the car, usually at a lower bumper opening or at a grille opening.

I prefer the grille openings as most VAG cars are designed to have the intake stream draw from the highest pressure airzone outside the car which is usually the leading edge of the hood. This is backed up by wind tunnel testing done by VAG and is the best place to get the freshest, coolest air into the turbo/engine.

Filters that don't draw from outside air will typically give you an improvement in throttle response and a nice sound.

Filters that draw outside air will improve hp, trq, fuel economy and throttle response as well as giving you a nice sound.
