Brand new at this, looking for feedback on spark plugs and front rotors
I have a 91 300zx (non turbo) and have only put on maybe less than 10K kilometers and I need to change front rotors as they are vibrating again. Is this an inherent issue with these cars? I do store it during the winter, could that affect it?
Also want to change original plugs (only have 60,000 Km on car). Dealership says NGK PFR 6B-11, but can only find PFR 6G-11, are these still OK? Any experience with NGK bkr5eix11 Iridiums?
Thanks

Those plugs are in the car for a reason.
Use the OEM ones youll get at the dealership.
As far as the rotors go, maybe its a weird wear issue but I dont drive my z in the winter either and I never had problems with them
Are they the right rotors? Did you maybe put the back ones on the front? (not sure if thats possible) Did you buy shitty parts?

PFR 6B-11 and PFR 6G-11 are the same plug so either will work and are the OEM plug for the NA. The Iridiums work great also according to several people from other message boards that I consider reliable. I'm running the single platinums from NGK with no problems either but they won't last 60k miles like the PFR plugs.
Warped rotors are not normal from my experience. Are you using good quality replacements or having them turned? Also make sure to torque your lug nuts down evenly.
