I’m looking for advice on which spark plugs work best for the Suzuki Swift 2021 Hybrid K12D engine.
The owner’s manual doesn’t specify the exact spark plug model. I’ve noticed engine knock when the car is hot and at low RPMs could this be caused by the wrong heat range in the spark plugs? There’s also carbon buildup on the injectors which makes me wonder if the plugs are too hot or too cold and affecting combustion.
If you’ve replaced spark plugs on your Swift Hybrid, which ones worked best? Should I go with a hotter or colder plug to prevent knock and buildup?
