Leave the competition guessing, and order one of these spark plug indexer tools from Jones Racing! Product features: * Billet aluminum construction * 14mm thread * Helps you line up the plug's electrode so it doesn't shield the spark from the air/fuel charge or obstruct the flame forward into the chamber * Available in 8- or 9-hole configurations * 9-hole configurations make it easy to install new plugs with your preferred setup * Also useful when storing, washing, or changing your engine

If you perform engine work, Allstar Performance spark plug indexing tools are extremely helpful in getting the job done right! It's no surprise that high-compression engines run better when the plugs have been indexed. These handy devices fit 14mm spark plugs, positioning the ground strap properly for the best piston dome clearance; they'll work fine with either flat gasket or tapered seats. In tandem, the index tool unshrouds the electrode for a more even burn and possible gains of 5 to 15 hp. Instructions are included for easy operation.
