Hyundai has released a TSB (#05-20-002) "Use of aftermarket engine oil filters causing engine knocking noise.” The TSB notes that, “Some vehicles may experience an engine knock noise with the use of aftermarket oil filters. Aftermarket oil filters may use different materials, construction and specifications than genuine Hyundai oil filters, which may lead to pressure variations within the engine, thus contributing to an engine knocking noise.”

Save yourself the hassle, use genuine parts! Filters include o-rings and drain plug gasket.
Please include your VIN number to ensure you recieve the correct filter.
