Hello all!

I'm working on a 2010 Versa Sedan with over 150k miles on it, and per research it's recommended to replace the timing chain around this point. I'm leaning towards getting a complete timing kit to replace all the main timing components while the engine's open. I'm looking for advice on reputable brands/companies to buy the chain/kit from, and any to avoid.

Also while working on the engine, and since the gas mileage has been dropping a bit, I'm also going to be replacing the spark plugs and plug boots (using NGK Laser Iridium plugs and NGK boots). I'm trying to determine if with the current age and mileage it'd be recommended to replace the ignition coils as well at the same time, or wait to see how the other repairs work out first. The new coils will add a few hundred to the overall cost, which if unnecessary I'd like to avoid.

Thoughts?
