Chevy Big Block Spark Plug Retainers

These spark plug retainers work great for holding my Chevelle BB larger diameter wires.
I have tried 3 different types of spark plug retainers that all bend over and broke.
There retainers hold up to the higher temperature and retain the spark plugs when the engine is moving.
Would recommend these spark plug retainers.
