Hello fellow members, My spark plugs are due for a change. Can someone recommend a brand and also I noticed some of them you need to adjust the gap which I don’t wanna do. I’m looking for a direct fitment without having to mess with the gap. Thanks! 🤙

 

I changed my plugs at 107k and replaced them with NGK 93420 LFR6BHX Ruthenium HX; they were pre-gapped.

 

Are you switching from OEM spark plugs? If so, why? OEM brand is Denso.

 

I totally agree there ^^^ , don't see any reason to change. Stick with OEM Denso, they do make the best stuff out there. I did change to the racing variant which are amazing, you will pick up some low end torque and a discernable higher pitch exhaust sound along with some nice down shift notes. Only drawback is the racing variants have half the lifespan of the regular ones at best.

 

OEM is Denso 3515 (FK20HBRJ8). Proper gap is 0.8mm if looking at other brands.

 

I was looking at those but they told me I have to gap them to the correct specs which is 0.31 for the RCF.

 

.....or get a tune. Is your engine stock? Again it begs the question, what are you trying to achieve? The OEM Denso ones are pretty darn good

 

Get the OEM ones and you won't need to mess with the gap as they come pre-gapped (which is what you're looking for) Won't hurt to verify them just in case though. They will last a very long time too. 0.031" or .8mm (.787mm) is the proper gap.
