B&B Spark Plug Index Washers

Product images may differ from actual product appearance.

B&B Performance Sales has introduced Copper Spark Plug Washers which allow any plug to be indexed for a particular cylinder. The soft copper gaskets are available in 3 thicknesses; installing thicker or thinner washers permits a racer to adjust the electrode's location when the spark plug is torqued in the cylinder head. Even when piston dome interference is not a factor, B&B spark plug washers provide a performance improvement by positioning the spark at the most desirable location for proper flame travel.
