Just wanted to check if anyone know what is the heat ratings on the factory plugs and/or what is the best aftermarket replacement for the factory plugs?

I'm currently running Denso IK16 in my 2.4L I4 and somehow feel that the engine is not idling smoothly; I get fair amount of vibration in the cabin.

Could I have gotten the wrong plug for my car? What plugs are the dealership putting in when you get your cars serviced and what aftermarket plugs are you guys using?

Top of the line Denso Iridium comes from the factory.

The NF has Iridium spark plugs. Unless you're already at 100,000 miles you are wasting your money replacing them.

Hmm...

The dealers over here aparently insist that there is a need to have them replaced every oil change and the replaced the factory plugs with something really cheap which I subsequently replaced with Denso IK16.

Just wondering what should the actual heat ratings be cause the dealers over here are real crapy it's been 3 years and they still cannot fix the sound in my dashboard.

The Hyundai part number for the plugs that go in the Sonata 2.4L is 27410-25000. Taking the plug out of the box, the writing on the plug itself says IRIDIUM on one side, and on the other side it says DENSO SK16PR-A11

Maybe this helps, I don't know. It's all I can contribute... lol.

There is NO reason whatsoever to replace iridium plugs before 100k miles, unless there is something wrong with one of them.

Read my experience with Denso IK16 plugs from a different forum Denso Iridium Problems

The "factory" iridium is a long life plug that has a larger iridium center electrode and a platinum tipped ground electrode. Check the link here www.sparkplugs.com mouse over the links on each and it will give a description on the left.

V33-are you gonna try the pulstar plugs next for us?

Hey LilBean & Sequoiasoon, many thanks.

Those were very useful information for me. Guess I'll head for the Hyundai spare parts dealer and get a set of plugs from them when my car hits 100K.
