Piaggio 263726 Complete Air Filter Box – Ape Car P2, P3 and Ape P501, P601, P400V Petrol (1972-1986)

The Piaggio 263726 complete air filter box — the air cleaner box — is the original spare part for Ape Car P2, Vespa Car P2, and Ape Car P3 (1972-1986) motor tricycles, and for the Ape P501, P601, P601V, and P400V (1978-1983) series, all petrol-powered. It is the housing for the filter element, supplying clean air to the carburettor: without an intact box, the engine will suck in dust, the carburetion will go out of sync, and wear will accelerate. New replacement part, original Piaggio code, available for immediate delivery from Moon Bike S.r.l. — Cercola (NA).

Who it's perfect for

This spare part is the right choice for anyone who owns an Ape Car P2 or P3 or an Ape P501, P601 or P400V and finds their filter box cracked, heat-deformed, with broken fittings, or patched with tape and silicone from some makeshift repair. On vehicles over forty years old, the air cleaner box is one of the hardest parts to find new and original: it's a purchase for those undertaking a serious restoration, and for those who still use their Ape daily and want the engine to breathe clean air.

Frequently Asked Questions

Does the 263726 fit my Ape Car P2?
Yes. The Piaggio spare parts catalog indicates this code for Ape Car P2, Vespa Car P2, and Ape Car P3 from 1972 to 1986, as well as for Ape P501, P601, P601V, and P400V from 1978 to 1983. For other versions, send us the frame number and we will check.

Does it also fit diesel Ape vehicles?
No. Code 263726 is for petrol versions. Ape Car Max Diesel and Ape Poker Diesel use a different filter box: ask us for the correct code for your vehicle.

Is the air filter included?
No. Only the complete filter box is supplied. The filter element must be ordered separately, and we recommend changing it along with the box.

Is it an original spare part or a reproduction?
It is the original Piaggio code 263726, new and never mounted. For these vintage models, it is a part that is becoming increasingly rare to find.

Is it better to repair it instead of replacing it?
On vintage Ape vehicles, it's common to find boxes patched with tape, putty, or silicone. This solution doesn't last long: as soon as the repair fails, the engine starts to draw in unfiltered air again. Dust is the main cause of premature piston and cylinder wear, and a new box costs much less than rebuilding an engine.

How long does it take to arrive?
The item is available in stock and shipped from Italy. You will receive the tracking code as soon as the package departs.
