Colder Spark Plugs for the E55 - NGK LFR7AIX #2309

Looking to get some new plugs for the E55, many have said that a colder plug should be used to reduce EGTs (Exhaust Gas Temperatures) when adding more power - basically one step colder per every 75HP added. NGK LFR7AIX Iridium IX Spark Plugs have been recommended by many on the popular sites.  Granted, on the E55 - 16 plugs are needed - YIKES!

These are a great set of plugs! Really smooths out the idle and helps to keep exhaust temps under control!
