Arnold Corporation FF-10 First Fire Replacement Spark Plug

Not necessarily much to say except the fact it works and the mower starts right up.

Just what I needed. Great product. 1st one lasted for years.

Spark plug is just what I needed to get my lawn mower started. Received it fast and easy to install. Grass is cut for last time this season

Couldn't find a replacement spark plug for our lawnmower locally now that Sears are gone but this one worked perfectly. Our lawn mower is back up and running again.

Works. But then it's just a spark plug.My twenty-year-old mower died. This year I had been negligent in performing usual maintenance expected. On the last mow of the season, mower decided to stop. I fiddled with the thing but no go. The old plug looked really dirty so I guessed that was the problem. Of course, it was the end of the season so all the stores were out of stock of lawn mower accessories. I combined this with a couple other items to reach Amazon's free shipping threshold and it arrived within a few days. Stuck it in and the mower fired right up. I can't comment on the durability at this point, but it appears to be excellent quality and durable. What should be expected in a spark plug. Generally they should go for about a year as they just get dirty. Back in the day they used to clean plugs with a sand blaster machine. No longer, just throw-aways.

Spark plug works well and engine starts easily. Only issue was there was a small piece of metal sticking off the threads. Came off easily, but could have been a big problem if it hadn't been noticed and broke off into the cylinder.

Inexpensive, not impressive, but it does what it needs to do. Not sure how long it will last, but small engine plugs seldom wear out, and are more likely to be changed because of anti-knock additive build-up or carbon fouling than wear.

Purchased for our ‘farm mule’ as we could not find the exact plug locally where we live.

fired right up after installing

Worked great replaced in lawn tractor and started up no problem had replaced the old ones(same make) after 3 yrs of use.

très satifait

My snow blower had an champion plug. Got this one as it was half the price and an add on item for $5.48 so I bought 2.No complaints, put in the new plug and it feels and sounds like the engine is running smoother. Maybe because I haven't changed the spark plug since I bought my snowblower 10yrs ago. Lol.

They fit perfect! Just had to make sure they were gapped before install.
