I like Taylor wires. The ~35$ 8mm has been the longest lasting wires ive yet tried...all.others were misfiring at~2years. I got 10years from that first set of.taylors and bought the same again when plug wire.#2. The longest one..became weirdly intermittent at temperature.
There's something about how sp wires get baked under a van doghouse that reduces their timespan viability.
The champion plugs...well i get it.. but prefer NGK.
Theres lots of heat range conversion charts out there.
I recently installed. https://www.ngk.com/ngk-3459-zfr5n-v-power-spark-plug
Ngk 5 = champion 12,....in terms.of heat range.
My most previous ngk gr4gps still have plenty of life and were in xcellent condition...but the zfr5n idles smoother both cold and hot...wi5h a better throttle.reaponse...and i just got the best average mpg.on a cross country journey using them.
Need a 5/8 " deep socket for them vs the 3/4"for the 12nyc
Find a distributor.cap with brass...not aluminum contacts.
Some cap and rotor kits.come with a rotor that must be for a 360 and is of wider diameter.
Ive one or two brand new rotors that were .too big
