What is the difference between Ruthenium and Iridium?JIm R.Aug 08, 2023
Best Answer:Hi Jim, I'm pleased to assist you. Both the spark plugs are durable and have anti-corrosive properties, however, ruthenium spark plugs have an upper hand in terms of durability as the period of replacement of the spark plugs is 1,00,000 km when compared to the Iridium plugs that wear out at every 80,000km. Click the link below to order the Ruthenium plug while supplies last. Your order will come with a 30-day post-purchase price match guarantee. Enjoy shopping! <a href="https://www.carparts.com/spark-plug/ngk/ng94279?can=CPGG4850_CSQA_20230808" target="_blank">https://www.carparts.com/spark-plug/ngk/ng94279?can=CPGG4850_CSQA_20230808</a>

How is this plug for oil fouling? 2007 CamryDale B.Oct 19, 2022
Best Answer:Hi Dale, I'm glad to assist you. It will react the same way as any other spark plugs out there. Once oil enters the combustion chamber, any spark plug will accumulate oil deposits that keep the spark from arcing across the gap. I hope this helps, and happy shopping.

Wonderful spark plugs. Comes with the spec gap and works like a charm. Seems to have fixed the idle issue I had as well! Thanks
