Incorrect plug
I entered my car 2000 Infiniti I30 with 3.0 V6 to look for spark plugs. A spark plug that is incorrect for my car is shown on your site stating its correct for this car.
It is Denso SK16PR-L11. The correct plug shown on Denso's site is Denso SK20PR-L11.
The difference is the 16 in the number witch is the heat range. A 16 installed could in fact due major internal damage to my engine including burning a hole in the piston if the cars driven on a very long road trip and since they can be installed for yrs and up to 100,000 miles these days it eventually will take its toll on an engine.
It is a hot plug and not the original heat range plug for this car. Please visit Denso's site and update your plug info.
Thank you

Never Buy These Plugs
I purchased 8 of these a little over a year ago for my Honda Insight and they have been a nightmare. The engine started missing after awhile so I checked the "new" plugs and found that cylinder #3 plug anode was missing! OMG,that means it went through the engine. I replaced it and ordered new Honda plugs. Before I could put the new Honda plugs in Two more of the DENSO plugs failed the same way, anode fell off in the engine. Bad news for me is that after replacing the defective plugs the engine is still missing on cylinder #2, so this means that something else is damaged. See the picture.
