I reviewed the spark plugs available for my CX7. The types available are Platinum, double Platinum and iridium. There is a discrepancy between my Owners manual which has a recommended gap of 0.028-0.031" The replacement plugs are listing 0.035-0.051" Has anyone looked at the plugs in their CX7? What is the manufacture, plug number and type i.e. double Plats or iridium or ? Thanks Ed
