Even aftermarket parts seem a bit high for the Mirage. If I buy items for my Forester & Mirage at the same time, I will notice this. Using rockauto.com for example -
The cheapest cabin air filter they have at the moment -
Mirage = $13.76
Forester = $3.56
Cabin air filter for a Mirage is pretty small & flimsy, too!
The cheapest engine air filter at the moment -
Mirage = $13.02
Forester = $3.35
Not comparing apples to apples exactly, but the highest priced engine filters for a Forester are still under $10. Rockauto.com charges shipping, & I do shop elsewhere, too. I am just using them to compare prices here.
