Description

NGK Iridium Spark Plug Track Set

Normal Rx8 NGK plugs cannot stand up to the arduous conditions they experience on a fast road/ track environment, the result is after a short time you may find that the road going spark plug set loose their electrodes and fall into the combustion chamber, this can have major consequences. After a lot of track miles we have found the R7420-9 -NGK Racing Spark Plug to be the perfect set for track use on naturally aspirated Rx8’s giving both great performance and durability.

If you use your Rx8 on track then we feel this kit is a must to protect your car’s engine from possible failure.
