Not the best
Makes sounds I can’t explain was installed by a certified Subaru tech. The customer service, (from ISC is horrible), NOT Import image racing. Tried reaching out multiple times with no response, also tried to register them for a warranty with no luck….
Import Image Racing
I'm sorry for your troubles with ISC. We are always happy to help and suggest trying a set of Silvers neomax next time for the upgrade. Headache free, with a real 5 year warranty.
