What made you choose this particular product?

Looking for ways to help the engine prevent heat soak and or aid in cooling. This car seems to very proun to engine knock via heat and engine load, espeically in the summer.

Is this your first time buying from this brand? Did you consider other brands?

It was the first time. In the Subaru community, however, Koyorad is praised as you of the best overall cooling brands.

Was it easy to install? Any installation tips that will help others?

It is just a radiator cap. Easy swap out and in. Like all things, just go easy initailly to make sure a smooth full seal in made. No rushing.

Once you've had a chance to use the product, did it meet your expectations?

So far so good, along with some other changes to the car, the audiable knock has gone into remission.
