Very glad I was able to find...

Cary November 23, 2025

I was looking for the Champion brand to replace an off brand on my riding mower. As the end of the cutting season came near and time to do the preventive maintenance, I was very pleased to find this spark plug at such a great price. The performance of the Briggs Stratton 17.5 hp was noticed on the first start after changing from the old plug. The old plug looked very good but didn't have the same quick start as the Champion. Very glad I was able to find this replacement at the right time.

Fits my Craftsman T2500 mower and Craftsman slowblower. Works good. Even though a 2 pack, came in individual boxes, not lose in bags like many other 2 pack reviews state. The point on one was completely pinched shut, but I have gap tools so was able to set it correctly.

The Champion spark plug got my walk behind lawnmower working again after I thought it was permanently broken. I kept pulling on the cord and it wouldn't start, I added fuel and pulled on the cord and it wouldn't start, then I cleaned the filter and pulled on the cord and it wouldn't start. I figured that I'd buy a spark plug since the old one was blackened (I tried cleaning it, but it didn't work) and it was shipped in 2 days. I installed it and on the first pull it started. The next time the walk behind mower fails to start I'm buying a spark plug or several just to be prepared. I'd recommend this spark plug manufacturer.

Quality part

Rich May 29, 2025

The spark plug was ordered for a Cub Cadet lawn tractor. Ordered online and shipped to the house within a few days. The cost was not much more than having to go to the store and picking one up. The spark plug was correct size and fit as it should.

Works as Advertised

David April 13, 2026

This spark plug works great for small engines in lawnmowers. Not too expensive and gets the job done. After ensuring the proper gap and installation, the lawnmower I put it in started right up and ran great!

the best brand of spark plugs

Anonymous July 16, 2024

I needed to change the spark plug in my John deere riding mower.I got a off brand from a auto parts store and and they said it was comparable to the Champion brand. Well it wasn't!. I installed it and the mower didn't run smoothly. So, I ordered one from Walmart and it arrived very quickly.I installed it and now my mower is working great again!!

Right Replacement

Robert April 10, 2024

It's an exact replacement for the Champion RC12YC spark plug in my Briggs %26 Stratton engine on a Poulan push mower. It arrived in a timely manner. Unfortunately, I've figured out it's not part of the problem, as I am not getting a charge from the mower to the plug when I pull. I'm in the process of tracking down the why...but the plug is a a real Champion. I shall keep it for future use.

Lawn Mower Spark Plug--OEM Replacement

WalmartCustomer March 25, 2024

Arrived fast and in good condition. These are the recommended spark plugs for my lawn mower. (I ordered two to have one as a spare.) The old one is needing replaced--it has a lot of dry carbon fouling and has been in there for more than a few years. This should help get my lawn mower ready for the spring and summer.
