I wonder if you could put some general guidelines on your product page to help the buyer determine which style are most likely appropriate for a given power plant? I have a tough time deciding which ones to use on my builds.
Yes, I know about this...
I need to take some care to my website.... I still postpone it. I still haven't enough time. But it's necessary - it's a shame to have such webside.
So...I HEREBY PROMISE:
- finish detailed instructions,
- prepare guide for using of spark plugs (the more at least three new spark plugs will be released in nearest time

- put more detailed pictures of product
- put more documentation for each product
I think it will be slowly upgraded and finish up to the and of August.
