Oil filters are important for cars. They keep the engine clean. Filters trap dirt and debris. But are all oil filters the same thread? Let’s find out.
Understanding Oil Filters
Oil filters come in many sizes. They have different threads too. The thread is the part that screws on. It connects the filter to the car. If the thread is wrong, the filter won’t fit. This is important!
Why Threads Matter
Different cars need different filters. Each car has a specific filter size. This includes the thread size. Using the wrong thread can cause leaks. Leaks can harm the engine. So, choosing the right thread is key.
Types of Oil Filter Threads
Threads have different measurements. These include diameter and pitch. Let’s look at the two main types:
- Metric Threads: Measured in millimeters. Common in European and Asian cars.

Each type has many sizes. So, it’s crucial to know your car’s needs.
