Spark plug musings

... haven't found any definitive answers on whether or not it is worth it to upgrade or just stick with stock NGK plugs. I'm also curious if it makes sense to go with some better silicone plug wires.

Our Outlanders already turn out lots of power so what would you hope to gain ? I've never been one to try and "re-invent the wheel" so I'd go with "stock"

Plug wires - Every hot rod nut I knew growing up used to upgrade his wires from stock. Seems like a common thing to do on various racing vehicles, why not an ATV?

Spark plug - not saying it will or won't increase power, but maybe give better fuel mileage and cleaner burn on fuel? I've read some opinions stating the Platinums and Iridiums might better resist fowling?

It was mainly a curiosity question to see if anyone has tried it and did it make a difference. If folks are willing to spend $1k on a tuner and pipes, change from CanAM oil to Amsoil, install uni filters etc.., I just thought someone might have spent $14 on plugs or wires? I agree stock works, but figured I throw it out there.

I put Iridiums in my 1000. I changed them at around 5000KMs. I found the bike did start a bit easier but it may have with just new normal plugs too. I felt no difference in power or acceleration. Never noticed any mileage gains or loses. My thoughts: stock bike. stock plugs are good enough.
