Before you order it's important to measure the outer or interal diameter of your intake pipe depdning on which filter style you are looking for - this measurement determines the correct neck size.

Then choose the filter height and diameter that best suits your available space in the engine bay.

Please see the above video for tips on determining your correct filter size. 

We have filters for almost all fitments. To confirm the correct fit, please ensure your intake pipe diameter matches the filter’s neck size. Always check:

- Neck size
- Available clearance
- Filter orientation

and you’re good to go!
