Omix-Ada is a Chinese owned brand, hard to say what is in their kit which I wouldn't go with. Instead, I would simply buy the parts locally instead of online.
Ask for a distributor cap & rotor with brass contacts which last longer than their cheaper counterparts that use aluminum... which I would bet is what comes in the Omix-Ada kit.
For spark plugs, two 100k mile platium plugs that would be good choices are the Autolite AP985 or the Champion 3034. The 200k mile spark plug mentioned above by WredTJ is the Autolite iridium-tipped XP985.
