Car Maintenance in May 2025: Air Filters, Spark Plugs, Brakes, and More
When it comes to keeping your car running smoothly, car maintenance, the routine checks and repairs that prevent breakdowns and extend vehicle life. Also known as auto upkeep, it's not about fancy tools or expensive visits—it's about knowing what to watch for and when to act. In May 2025, the most common questions from readers revolved around simple but critical parts: air filters, spark plugs, brake pads, and radiators. These aren’t optional upgrades—they’re the backbone of reliable driving.
Air filter, a component that cleans the air entering your engine. Also known as engine air filter, it’s easy to ignore until your car starts struggling. A clogged filter doesn’t just hurt fuel economy—it can damage your engine over time. Then there’s spark plugs, the tiny devices that ignite fuel in your engine cylinders. Also known as ignition plugs, they wear out slower than people think, but when they fail, your car might misfire, stall, or refuse to start. And don’t forget brake pads, the friction material that stops your wheels. Also known as brake linings, they don’t last forever, and waiting too long can cost you rotors, calipers, and your safety. Even something as simple as checking your radiator, the part that keeps your engine from overheating. Also known as cooling system radiator, can save you from a roadside breakdown. These parts are connected. A dirty air filter strains the engine. Worn spark plugs make the engine work harder. Overheating from a failing radiator can damage the whole system. And bad brakes? They’re not just a repair—they’re a warning.
What you’ll find in this collection isn’t theory. It’s real advice from people who’ve been there: the driver who swapped their air filter and noticed instant power, the DIYer who replaced spark plugs and ended up making things worse, the owner who removed their rear wiper thinking it was useless—only to fail their MOT. These aren’t hypotheticals. They’re stories from readers who learned the hard way. You don’t need to be a mechanic to understand this stuff. You just need to know what to look for, when to check, and when to call a pro. Whether you drive daily or just on weekends, the fixes here are simple, cheap, and could keep you off the side of the road.
