Mitsubishi Mirage Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
On the Mitsubishi Mirage, spark plug wear tends to creep in quietly — idle gets a little rougher, throttle response softens slightly — the kind of symptoms that get blamed on almost anything else under the bonnet. Given how cheap the part itself is, it's an easy one to put off for longer than makes sense.
Mitsubishi Mirage Spark Plugs: What They Do
Inside each cylinder of the Mitsubishi Mirage, spark plugs ignite the compressed fuel-air mixture, and their condition has a direct effect on combustion efficiency, fuel economy and how smoothly the engine runs. Petrol engines can't function without them; diesels don't use spark plugs, relying on compression alone to ignite fuel.

A Genuinely Useful, Real Diagnostic Technique Worth Trying — Mitsubishi Mirage Spark Plugs
If you're chasing a single-cylinder misfire after a plug replacement, this is genuinely worth trying: swapping the plugs between two cylinders and seeing whether the misfire follows the plug to its new cylinder is a genuinely useful, classic diagnostic technique. If the misfire moves with the swapped plug, the plug itself is likely the culprit; if it stays on the original cylinder, it points toward the coil, wiring, or an injector instead.
It's also genuinely worth knowing an honest warning worth taking seriously: the relationship between Mitsubishi's electronics and aftermarket ignition components can be genuinely unpredictable, worth bearing in mind when choosing replacement coils specifically.
