- You shouldn't need to replace your plugs until ~161k KMs (~100k miles). 11,000 kms means these plugs are about broke in, not ready for replacement.
- These plugs look fairly healthy. I'm not seeing any carbon buildup; they don't look burnt; the electrodes look in good shape.
If you're having a performance issue with the car, I'd suggest you look elsewhere for your performance issue. While replacing the plugs won't hurt anything, at 11,000km you're just wasting money.
Your plugs look in really good shape. If rich, they'd be black and possibly wet looking. If running lean, they'd be very tan in color and possibly have degraded electrodes and bubbling on the porcelain. If these are the original plugs (assuming what you said is correct), I'd change out these plugs with new and not think a second about it. It may be time to replace the O2 sensors if that hasn't been done since new. If you've cleaned the MAF and throttle body, you should be in pretty good shape. You may also want to ensure the PCV is cleaned and is doing its thing. You may want to run some fuel injector cleaner (heavy duty stuff like BG-44k if available, or give it a SeaFoam treatment).
