Has anyone ever had a flow problem with this filter. I've used it before on my sonata with no issues but changed my oil today and used control 5W30 dino and a pureone and after I started my engine I notice valve noise that I've never had before. So I called the dealer to ask if there's been issues with after market filters in my application before they said its definently the filter so I changed to a OE hyundai filter And boom noise is gone!
Was this a one time occurrence just after doing the oil & filter change, or was it repeating the start-up noise every time you started it after the initial start-up after the oil & filter change? Like others have said, if the start-up noise was after the car sat for a while, it could be the ADBV wasn't sealing 100% and caused the filter to empty. Some cars are sensitive to empty filters, and some are not.
