Spark plug NGK or BERU

I just tossed some oem NGKs for the first time since... 30k miles, and they seem to be the best plugs I've ran, although they are not a step colder as recommended.

I ordered (from Rock Auto) some NGK spark plugs (#95463) advertised as being "OE Series." This supposedly means they are built to match the OE specifications.

I just replaced the spark plugs on my 2014 Cadillac ELR(essentially a gen 1 volt). My ELR has 81000 miles on it. It still had the factory plugs. One of the plugs was leaking compression as seen in the photo. If you have a first gen volt or an ELR, if the plugs have never been changed, it won't hurt to take a look at them. I replaced them with NGK 94279 spark plugs.

My wife has a 700ckx Heritage 2022 model. She has been riding for over 20 years. Bought this bike because of seat height and price point. Used almost every day for commuting. She just hit 40k's with no issues. We did change the plugs for NGK and swapped out the pipe. Also added a Scott's oiler for the chain. She loves it.

NGK Iridiums are what I run and never had a problem

If you’re asking about brands, I always go NGK. They’re definitely my preference. They have a coating on the threads and don’t require grease when you install. And they come pre gapped.

NGK !!!

Next day guy at the auto parts store tells me to try ngk iridium’s and it works automatically. If you’re planning to replace your spark plugs save your self the time and money and buy ngks over anything.

For the intake i would recommend k&n filters systems, racing plugs are not even worth it, better look it up some NGK iridium

Replacing a motor is not fun, nor cheap. That was with 9006 RS7's btw (your current plugs).
