There are a few signs that can indicate a defective spark plug. One common sign is difficulty starting the engine or frequent stalling. Another indication is poor fuel economy or a noticeable decrease in engine performance.

If the spark plug image is displayed in a warning light or indicator on a vehicle's dashboard, it may indicate a potential issue with the ignition system that should be addressed by a mechanic. **

You can tell if a cup is heat resistant by checking the material it is made of. Cups made of materials such as borosilicate glass, tempered glass, or certain types of ceramics are usually heat resistant and can withstand high temperatures. Look for labels or product descriptions that indicate the cup is heat resistant or safe for use with hot liquids. Additionally, cups that are specifically marketed as being suitable for use with hot beverages are likely to be heat resistant. **
