Owner reviews for spark plug

41-156 is the new plug for the LE2 engine. Our 2016.5 got them, and they are fine. 41-123s came out of it.

Most of my guys like to go with NGK plugs

That’s hilarious I just swapped the exact same plugs this morning in my Lotus, cheapies for iridium, what a difference.

The new NGK spark plugs do not need anti-seize per NGK. The anti-seize is already in the metal.

So the BKR7EIXs are in and gapped to .028. Man what a difference. Everything is so much smoother and the engine doesn't feel strung out anymore.

I remember the first time I did anything besides oil, it was spark plugs and power steering fluid on my old accord. Starting it up after had me nervous, second guessing everything I did.

I run 0.024 but I’m running Brisk plugs in my car on a custom tune. They’re pre-gapped to 0.026 and anywhere between those two would work fine for my specific plugs.

I'm running PFR7Bs. I get a misfire or 3 here and there, only during low load low speed acceleration. I've got R8 coils too. Not sure if the RFD makes them occur any more frequently than they otherwise would, but I'm not worried about it.

Skip them, they are junk and a waste of money.

Get a good single platinum plug like the Denso 4511.

Champions are crap.
