Rated 5 out of 5 by from 4-Cycle spark plug is just what I needed, auto parts stores nearby did not carry it. This spark plug is just what we needed. RYOBI is a great brand! Local auto parts stores did not carry this type or size of spark plug (small). The local Home Depot store did not carry it in stock either, which is strange since we purchased the weed trimmer at Home Depot. However, I was able to find it on your website. We received this spark plug in just two days and our trimmer is now back in business! Thank you. E.
