What made you choose this particular product?
Only 4" air filter adapter I could find.
Is this your first time buying from this brand? Did you consider other brands?
First time. But I will be buying a filter from them
Was it easy to install? Any installation tips that will help others?
It does not fit a mk3 Supra with the included adapter plate. I had to custom make an adapter.
