    New Moroso spark plug indexing washers. These are for 14mm flat seat spark plugs. These washers are used for both spacing the spark plug away from pistons on tight clearance applications, as well as proper orientation of the electrode in the cylinder head. For maximum performance and fuel burn, you want all the electrodes to face the same direction and point towards the exhaust valve. Having the electrode opening point towards the exhaust valve typically gives optimum burn. Having the electrode opening point too much towards the intake valve can cause the spark to be blown out, even more so on turbocharged and supercharged applications. You can either mark your spark plug with a marker on the ceramic on the electrode open end, install the spark plug, take notice of the mark, and add shims as required to get the proper orientation. A tool is also available separately. This included 30 total indexing shims, .043", .050" and .064".
