Φίλτρο αέρα 320i E9x

[Cobalt]

Αμα δεν σε χαλαει ο πιο σπορ ηχος, και το οτι το καθαριζεις αντι να το πετας (οεμ), δεν ειναι αχρηστο.

Σωστά...

και στην τελική τι παραπάνω περιμένει κανείς απο ένα φίλτρο αέρος να κάνει?
ιπποδύναμη δεν κερδίζεις ή τουλάχιστον δεν καταλαβαίνεις τίποτα σαν διαφορά.

Δηλαδή δεν ισχυεί τίποτα από τα παρακάτω ;

1.How will a K&N filter affect my vehicle's fuel economy?

There is a relationship between air filter restriction and mileage. The theory behind this is simple, the harder an engine has to work to suck air through the intake tubes and air filter, the more gas gets wasted in the process. Many K&N users report an increase in their fuel economy after beginning to use our air filters, as noted on our testimonial page. However, these experiences do not mean you will also experience a change in your mileage. We certainly understand why it is theoretically possible for a consumer to experience a mileage increase after installing a K&N air filter or intake system, however, we do not go so far as to make a general claim that our air filters and intake systems will provide an increase in mileage.

It is virtually impossible to make sweeping and general claims about mileage. Even the EPA fuel rating numbers for new cars are often not representative of the mileage you actually experience. There are many variables that affect mileage such as: tire inflation, the type of fuel, weather, elevation, the speed at which you drive, the gear in which you drive, the speed with which you accelerate, engine maintenance, excessive idling, cruise control, the grade of motor oil you use, and of course, the condition of your air filter. In short, mileage is complicated.

K&N filters are less restrictive than disposable paper or synthetic air filters and K&N Intake Systems are less restrictive than the factory installed air path. So K&N filter technology could be an important tool, when combined with other elements, to help keep mileage as high as possible.

Oh yeah, there's one more limitation imposed by science. If you take advantage of added power by driving more aggressively, you will reduce mileage. You cannot have your cake and eat it too.


2. What increase in horsepower should I expect from a K&N replacement filter?

K&N direct replacement filters which install into your vehicle's factory air box can provide an increase of between 1 and 4 horsepower. Results will vary depending on your vehicle, driving habits, load on the engine (towing for example), existing air system restriction, and other factors.


3. What increase in horsepower should I expect from a K&N air intake system?

K&N makes several different types and configurations of performance air intake systems. Depending on the year, make, and model of your vehicle, only one style of intake system may be available for that vehicle. All of our intake systems are dyno-tested and guaranteed to increase your vehicle's horsepower. Instead of making a general claim, we publish actual intake system horsepower increases for many part numbers and vehicles. To see the power gains of specific air intakes for specific vehicles, enter the part number in our part search or look up a specific vehicle in our application search.


4. How often do I need to clean my K&N air filter?

If you have not experienced a decrease in mileage or engine performance, chances are your filter is fine and does not yet need cleaning. To be more specific, the filter does not require cleaning if you can still see the wire screen on the entire air filter regardless of how dirty it may appear. When the screen is no longer visible some place on the filter, it is time to clean it. When used in normal paved road, street or highway conditions, our replacement air filters that fit in the factory air box should require cleaning every 50,000 miles and our large conical filters on an intake system should require cleaning every 100,000 miles. When used in dusty or off-road environments, our filters will require cleaning more often. We recommend that you visually inspect your filter once every 25,000 miles to determine if the screen is still visible.

αν είχες διαφορά σε κατανάλωση θα είχες και περισσότερη ιπποδύναμη

Επειδή η αλλαγή του ήχου θα μου άρεσε, αλλά διάβασα και αυτό:

Re: K&N 57i Air Filter
Don't do it! Sounds good, but will kill the power with heat soak!!

Ισχυεί κάτι τέτοιο;

Εξαρτάται απο την τοποθέτηση που θα κάνεις...

κοίταξε να τοποθετηθεί το φίλτρο όσο πιο κοντά γίνεται στις γρίλιες εισαγωγής αέρα του κινητήρα και μακριά απο την πολλαπλή εξαγωγής καυσεριών.

δεν θα έχει προβλημα έτσι...

φοράω κάτι ανάλογο...

Το έχω κανά 2μηνο στο πορτ-μπακαζ. Που να πάω για εγκατάσταση;

[Nick bmwlover]

Δεν ειναι τπτ δυσκολο,το "μαμα" φιλτρο αερος ξερεις να το βγαζεις?

[drbiloukos]

Κάτι λέει στις οδηγίες να σηκωθεί και να κοπεί το πλαστικο από κατω για να βγει η σωλήνα. EIKONA 8. Δεν μπορώ να το καταλάβω...

[ΦΑΝΗΣ]

Το έχω βγάλει έδω και 1 μήνα,καλό ήταν! λίγο ήχο παραπάνω,και τίποτα άλλο,και ψιλόταιλαιπωρία στο καθαρισμό,καλό λούσιμο στο κουβαδάκι του,στέγνωμα,και μετά του βάζεις το λαδάκι του και είναι οκ!!...........((Ο Καθαρισμός γίνεται μετά από κάθε service,δηλαδή γύρω 12000χλμ. με 15000χλμ.))
