Ignition coil broke in two - how'd this happen?
 

After a few weeks of annoying MAF issues, then replacing the MAF but breaking a brittle piece of the air intake, when I put it back together with a couple new pieces and a new air filter last weekend, I expected a smooth engine again.

Instead, it sounded like a tank and upon checking the codes, I found cylinder 2 misfire - p0302.

Today I found the cause of the misfire being a broken ignition coil, I wondered how can one of these break like mine did?

It is the original Hansin part.

Are they original to the car? If so I'd think heat would make them brittle over time..I had my number 3 break in half not to long ago..not a big deal cause I keep 6 of each front and back as extras...(small town with a pull a part) I get them dirt cheap...as well as most other parts

I believe it was an original. Good idea to have some spares around. I should plan a trip to the local JY to practice taking off the UIM and the fuel rail as I want to refurbish my injectors and replace my FPR sometime soon.
