    So the NGK's are shorter reach? What part number is on the Bosch and what is the part number on the NGK?

    Definitely don't put those in, as delcowizzid said they're the wrong ones.

    If the car is running right the plugs should be burning clean regardless of fuel. Those plugs look ok and don't need cleaning.

    definitely change the plugs - you'll damage them trying to clean them. Prevention is better than cure, especially when it comes to duel fuel.

    If you buy new plugs get some Bosch standard platinum. I've been using them for over 10 years including dual fuel and never had an issue. Like EYY said don't clean them. A friend from up the road had a peice break off on his Prado and it meant a full rebuild as it trashed the engine. Don't know if he cleaned his plug or whether it was just a faulty plug.

    How much for the platinum plugs?

    I now run Autolite plugs, costs me about $20 for 6 plugs and they do 20,000 km before I change em out. Before that I ran those fancy iridium plugs that cost about $20 each.... Cost Vs benefit I'll take the stock type plug any day.

    I normally pay around $7 each for Bosch Platinum. They are the middle range in Bosch. Mine normally last 50k but can go longer, 50 is where I choose to swap them. I was warned against Autolite. Sounds like you are having no issues with them. I rocked up at my old mech garage with Autolite and he told me to them back as he wouldn't fit them.

    Standard NGK's I use tend to go around 40,000km before I change them. Don't think I've ever had spark plugs give me any issues at all actually but I only ever use NGK.

    Sometimes I wonder about the hype around plugs. Seems like some mechs will only use NGK, others say Bosch and some say Champion. Then you have Immortality who has used Autolite for years and had no issues. Really got to wonder if there are any plugs that are no good???
