Need new spark plugs.. and a few other things.
I installed a set of plugs at 240,000 kms. at 265,000 kms the insulator is now cracked slightly and it is showing some age, the plugs. I think its time for new plugs.
I am looking for some good quality plugs. Also, what heat range should I use? Curently it is at hot, (electrode sticks out)
Thermostat is a 195, and was thinking of changing that, what thermo should i get?
Keeping in mind, I have type 2 coils, from a 97 3800, so it should be the hotter plug. what gap should the plugs be set at? .060??
Anything else I'm missing for my spring tune up, other than a possible new fuel filter and o2 sensor?
It does not need new wires, those were replaced a year ago with quality wires.
Thanks. if its in the improper forum, feel free to move it to the 87-91 forum. thanks.
