Z31 300zx turbo spark plug replacement and tune up. 

Thanks ... I did plugs years ago and forgot most of what you showed ... the z31 spark plug tool is actually useful !

Spark plug number six... ughhh lol. Gotta have that key tool!

I sometimes just clean my old spark plugs if they're not extremely rusted and I'll just take small fine file and clean it first with a wire brush then gently fill em but tap the point if I can 🤷😂 but mostly just try to get new ones
