I find the car runs way better on the Rutheniums, and I find that the plug gap doesn’t open itself up over time like it was with 6510s.
I went NGK and noticed a small bump in throttle response, changed mine at 100k Km (60k miles) and they were honestly good to throw back in too, so not like the plugs were burnt or fried!
I’ve been running NGK Ruthenium plugs on my stage 1 GTI for 20k miles. No issues.
NGK. I'm a believer after using them.
Went and bought the NKG plugs and the problems went away.
Most definitely still recommend! they are great, I usually replace every 50k due the stress I put my car under, but they can go a little more than that
NGK coopers for the coil pack Jeeps. Mines an 00 and have ran champion and NGK. NGK are doing alright in mine
I noticed a slight miss at while cruising between 67 and 70mph. I ran VCDS logs and found misfires on cylinders 3 and 4. Imagine my surprise when I pulled the plug for cylinder 3… no signs of any other damage and I have no idea how long it’s been like this. Never got a CEL.
I installed the new NGK Ruthenium HX plugs and so far everything has been great ????
I tried it once after reading about that. Used ngk plugs. One of them seized and snapped on me trying to remove it. Only plug I’ve ever had seize.
Ngk dcpr6e, DONOT use autolites...
