Air filters
SWNKDG 2× Luftfilter 550E/575EX
Two filters at 112 × 69 × 37 mm for three named engine series — with an internal reference that belongs to another product.
What the maker prints on its own page
An air filter for one named engine maker’s products, for three named engine
series. The filter replaces three stated references.
Length about 112 mm, width about 69 mm, height about 37 mm.
Contents: 2 air filters.
A different shape entirely
112 × 69 × 37 mm.
Most of this shelf is around 133 × 114 × 25 mm — a wide, shallow rectangle.
This is narrow and deep, and that is because it belongs to a different engine
family.
It is worth stating plainly: these filters are not alternatives to each other.
A shelf of air filters looks interchangeable and is not, and the dimensions are
how you tell before ordering.
The reference that belongs to something else
The catalogue record for this item carries a reference reading “Car Scratch
Remover Cloth”.
This page prints it as found.
That is not pedantry. A marketplace record with a reference from an unrelated
product tells a reader something real about how the listing was created, and a
site that silently substituted a plausible-looking part number would be
inventing one.
Two in a box
The only multi-pack on this shelf.
An air filter is a once-a-season part on an ordinary domestic mower and sooner
in a dry, dusty summer. A pair is two years, or one year and a spare for the
July when the first one turns out to be grey and stiff.
What is not said
The element material, and therefore the cleaning.
Paper never washes. Foam usually does, and on most engines is lightly oiled
afterwards. Four listings here say which; this is one of the three that do
not.
If you cannot tell from the listing, look at the part: paper is pleated and
stiff, foam is open, grey and squeezable.
Availability
From 10 € to 14 €, that being the spread across the German, French, Italian and Spanish Amazon stores on the day of the survey.
Beyond the euro zone, the British Amazon store prices it in its own currency, which the spread above sets aside.
Nothing came back from the American Amazon store at all; the buy button there runs a search rather than opening an empty page.
Taken from Keepa on the day this page was last revised; stock and prices move without notice.
