Where to Place a Magnet on the Exhaust Pipe?
2 Answers
Placing a magnet at the mechanical filter of the exhaust pipe can attract some magnetic particles generated in the oil return line, which helps protect the engine and enhances its power. With fewer impurities, the engine naturally performs more powerfully and can also help the owner save fuel. The magnet's adsorption capability is strong—any magnetic material will be attracted, thus removing many iron particles and extending the engine's lifespan. If you feel that your new car's engine lacks power after some use, you can try placing a magnet on the filter.
As a seasoned auto mechanic, I've seen many car owners stick magnets on their exhaust pipes, usually choosing the curved section or near the muffler where the airflow is slower, making it easier to attract iron filings. However, the exhaust pipe gets extremely hot, reaching several hundred degrees after starting, causing the magnets to either fall off or melt and burn, potentially blocking the outlet and leading to poor exhaust flow. I once repaired a car where a magnet got stuck inside, corroding the pipe and requiring a full replacement, costing over a thousand in repairs. Honestly, exhaust pipes have minimal impurities, so the magnetic effect is negligible—it's just a waste of effort. Focus on effective maintenance instead, like regularly checking the exhaust pipe seals and replacing worn parts. A better place for magnets is the oil filter. Avoid these gimmicks and truly protect your car, saving time, money, and reducing the risk of breakdowns.
