STL adapters for cone air filters (нулевик)

This collection gathers 3D models that connect a cone air filter, often called a нулевик, to an engine intake. The files are made for 3D printing and cover adapters, flanges and small mounting parts. It helps when the original intake part no longer matches the filter you have. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness.

«STL adapters for cone air filters (нулевик)»

The models fall into a few groups. Some are adapters that bolt to the throttle body, others are plates that carry an airflow sensor, and a third group is made of rings and couplers that step between two diameters. Brackets and simple holders appear as well, usually to keep the intake pipe from moving. The difference between them is mostly the mounting surface: a round flange, an oval one, or a plate with a specific bolt pattern.

Before printing, measure the inner diameter of the filter neck and the bolt spacing of the surface it attaches to, since a small difference makes the part useless. Check the wall thickness and whether the author notes supports for overhangs. Engine bays get hot, so look at the material and settings the author lists, and at photos of real prints, rather than assuming any filament will do.

If the results are thin, try other words: transition ring, flange, sensor housing, intake coupler, throttle body spacer. Related topics such as cold air intake, airbox replacement or intake piping often lead to the same parts. Adding the engine code or the car platform to the query narrows the list faster than browsing a general car category.

FAQ

Domande frequenti

What exactly is a нулевик adapter?
It is a printed part that joins a cone air filter to the intake, either directly at the throttle body or through a flange that holds an airflow sensor. Its job is to match two different mounting shapes and diameters.
How do I pick the right diameter?
Measure the filter neck and the intake opening with calipers, then compare both numbers with the dimensions in the model description. Bolt spacing matters as much as the diameter.
Which filament should I use?
Authors usually list the material they printed with, often PETG, ABS, ASA or a nylon blend. Check the temperatures the part will see in the engine bay and read the author's notes before choosing.
Do these parts need supports?
It depends on the shape: flat flanges often print without them, while tall adapters with overhangs may need them. The model page usually states whether supports were used and where.
