I've been running them with the Laser Iridium spark plugs since May this year...not really a long enough time to report on reliability...yet
But FWIW - its been good so far...

Ah yes, I forgot about that. That was me playing a shell game with coil packs and actually it was the same thing as I recently posted, showing #8 but really being #2 but I didn't pull plugs to confirm so I didn't know it. That BWD wound up on #2.

This week that so called Advance Auto Lifetime BWD (BorgWarner) coil failed and I lost the paper, and amazingly they didn't have me in the system that takes my phone number/email on every freaking purchase. Thats fine, I don't want another BWD coil anyways.

So I have had two #2 coils fail, an OEM andj a BWD. I guess I'll be metering and inspecting the wiring to #2 coil.

I went NGK because of time constraints and they seem to be a reputable Co. The box does indicate Made In Mexico.
I googled finding no NGK horror stories and inquired here.

Thanks

 

Those that have been in the game for a while have found that NGK and MSD coils don't work as well as OEM and most builders use OEM even on 1000+hp builds.

Nevermind, it was already linked [emoji2359]

 

Thanks. Looks like I'm a NGK coil pack tester then. No news on it will be good news as time passes.
