Here we have a set of spark plugs which were removed from a customers car, whilst in for it’s full service. It was clear that this car was in need of some tlc!

The white part is made of porcelain. Spark plug porcelain can crack due to temperature changes, impact, or internal cracks. The ceramic portion of the plug is brittle and can break easily, leading to cracks in the porcelain.
Additionally, the impact caused by engine vibrations and other mechanical stresses can also lead to cracks in the porcelain. When the porcelain cracks, it can affect the performance of the spark plug and may even cause a misfire. Therefore, it is important to handle spark plugs carefully and avoid subjecting them to excessive temperature changes or impacts to prevent porcelain cracking. If you know the porcelain is cracked, this should be addressed to prevent further damage to the engine, as the overall performance of the car will be affected.

These images also show the stress lines appearing on the porcelain part of the spark plugs.

Regular servicing on your vehicle is very important. It lengthens the life of the engine, and prevents further damage to other components, which could end up costing a lot more than it should have!
