Where can I get original denso lexus spark plugs. I replaced All 6 spark plugs 2 weeks ago with ngk tokunbo. And now my car shakes at idle,low speed,exhaust keeps sputtering eap when AC is on,my fuel consumption has worsened. I checked my exhaust,its a lil black,meaning unbunred fuel and oil are going there. Pls I want to buy original denso sparkplugs.i spent over 6k on tokunbo and workmanship yet on gear 1 and 2 the spark plugs seems to have low compression. Who sells original denso spark plugs or original ngk 6 plugs for 3.0 liter engine v6 at ibadan?

first check ur air filter before buy another plug.

Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.

When Incomplete combustion occurs and soot is formed when there is an overabundance of fuel (both diesel fuel and lube oil), insufficient residence time in the combustion zone, and/or non-availability of sufficient oxidants. Over-fueling is the primary cause of black smoke from the exhaust

Not really black smoke,but when I checked my exhaust pipe I could see a lil bit of black carbon deposit on the pipes because this morning I cleaned it,it wasn't so black. Does bad plug,coil cause oil burn. I don't over fill my car tank. The whole wohala started when I changed from the follow come ngk to a tokunbo plugs 6 and realised my vehicle rpm drops to 900,sometimes 1000rpm at idle,or traffic. When im on gear 1 or 2,it takes some few seconds to pick or has little power,tho no stalling but insuspect plugs 1 and 2 are bad from the same tokunbo I replaced.
