Warranty Disclaimer: Subaru of America only warrants parts installed on a car with a matching VIN by a CERTIFIED Subaru Dealership. For example, if you install an STi block in a WRX at a non - certified shop, don't expect a warranty claim to be approved if there's an issue.

Using this oil cooler is simple. Just have it installed by a certified Subaru dealership to ensure proper fitting and to be eligible for the warranty. When it comes to maintenance, regularly check the cooler for any signs of leaks or damage. Also, make sure to follow Subaru's recommended oil change intervals. Keep in mind that for the warranty to apply, the part must match the vehicle VIN and be installed by a certified dealer. Don't try to install it at a non - certified place if you want the warranty protection.
