You need to use caution when looking at NGK plugs for small engines.

Take the TR5 for example that Cowman mentioned. . An NGK TR5 has short threads while the TR5 -1 has long ones. Some unknowing clerk behind the counter may hand you plugs that could damage your pistons. So be sure to look at them before you buy.
