I recently purchased replacement parts for my automotive engine from this BRAND... Thanks to my knowledge gained in practice, I determined that the ValvoMax products fall well below the standard of quality expected for performance car parts & accessories. While the packaging and delivery were timely and convenient upon installation, the parts revealed faults and showed signs of wear. The only positive was that their customer service team responded promptly. The cons? I now have to search for another brand that can deliver the quality I require for my vehicle..
