I replace these plugs with fresh ones due to all the gap testing I've done. Turns out they did not like the .034" gap as the projected square on a few plugs had become heat worn. These brand new Rutheniums will stay gapped to .044" which "seems" to be the sweet spot for my particular application, exactly like the factory gap setting suggests. Go figure!
These plugs are being tested in a 1999 Toyota 2.2l 5S-FE normally aspirated 4 cylinder engine that currently has about 180k miles on the odometer, est 94% highway speed driving and 6% around town driving. This engine always runs great, however lately the idle is a bit lopy until the engine gets hot enough (even when these new plugs were installed). This has more to do with the idle Air Control (IAC), not spark plugs and I do my best to smooth the idle out manually by putting the tranny into neutral at stops (Just til I can look into this issue). The engine gets fresh quality Pennzoil Synthetic for high mileage engines every 5k miles, I also installed an oil catch can to keep the engine from choking on its own vomit and has new NGK 5mm ignition wires covered in heat-protective Tech Flex installed at the same time as the new Rutheniums.
I just poured in some AT-205 Reseal to help with a light rear main seal seepage.
