My daughters Q3 is running a Dayco kit and 20k and nearly three years later no problems, the only Gates logos to be seen out of dealer supplied boxes are Ford ,GM, Chrysler as Gates are an American company and their Gator Grip range is used by the military, I have seen multiple failures of INA equipment mostly because the bolts supplied tend to stretch and allow movement of components, the garage I use won't entertain INA anymore which is why I was alarmed at the logos everywhere on the belt kit I bought from TPS, I remember someone telling me once INA are owned by VAG which would explain their love of the brand.
