This past weekend we had an issue with the race car. It was running like absolute **** and we discovered that both lead plugs weren't firing. So we replaced the leading ignitor and it seemed to be alright until the hardship practice before the race when it still ran like ****. So we took out each plug individually and cranked the motor to see if they were firing and found that one of the trail plugs.... the little tube-shape ceramic piece in the middle that separated the positive from negative had actually BROKEN. We determined that since it broke, it was grounding on the plug and fucked up the leading ignitor.

OK enough story telling.... my point is: This isn't the first time this happened to us, and its happened to at least 4 others that i know of.

Has anyone else experienced or even heard of this? I have a feeling the problem lies within NGK because this never happened until the middle of this year.

Well, it could have been a bad batch.

The best thing you could do, is call NGK and notify them of the problem. Tell them where and when you purchased the plugs. They may ask you for some more info, like a serial number of the plug/packaging (if possible).

From there, they may send you a replacement. At least that way, NGk may be aware of the potential bad batch.

Interesting, Ive only had this problem with ND plugs.

We broke one of the NGK BUR9EQ's recently, but it was "user error".&nbsp You can't lean on the spark plug when it's installed, and that easily cracked the ceramic at the base where it meets the hex nut.&nbsp You need to be careful when installing and removing these things, as they are pretty fragile.
