Sorry, I couldn't tell a difference at all when I switched the plugs. I never really had issues to begin with on the stock plugs though. I changed them as preventative maintenance. Thanks for the positive feedback.
I haven't had any misfires. I'd recheck that the coil packs are seated properly and all the wires connected. Hopefully you didn't get dielectric grease on the spark plugs?
@@ruffwrenchn2235 Thanks for the reply In fact I turned my V8 Camaro by myself about 8 months ago, and I went with 1 step colder sparks plugs, Every thing was very nice and the car have a very noticeable HP gain, until when winter came it started to do miss firing in cold start in cold weather like 0 c or 32 F. But everything nice when it’s warm.

Great video, well shot. Interesting to see the bore scope shots. Well done.
I would like to see the front cylinder were the PCV goes into the intake manifold. See if there is any build up. We'll check it with the light
Love your videos. Did you notice any significant performance differences when transitioning to the colder plugs? Go Army

Please question, did you have some miss fire when the car is cold?

What time are you running?
Considering the mileage, that plug looked bad..
