Buying tips

When buying replacement igniters, always check your vehicle's owner manual for the correct spark plug type, gap, and heat range. Matching OEM specifications ensures proper ignition and engine performance. Consider iridium or platinum for longer life, but copper plugs are fine for older engines on a budget.
