## Customer Reviews

### ⭐⭐⭐⭐⭐ Kawasaki Mule KAF 400 Champion Copper Plus 404 Spark Plug
*by B***D on March 16, 2024*

Very easy install for Kawasaki Mule SX 4x4 XC Camo. It's difficult to find a plug to install for my Mule that actually states that it's for my machine. This plug works great. Improved starting of my Mule. Replaced the OEM plug with this. Great price and delivery. Highly recommended.

### ⭐⭐⭐⭐⭐ Champion RN12YC (404) Copper Plus Spark Plug
*by S***K on September 19, 2017*

I've been using these Champion RN12YC Copper Plus sparkplugs in my '90 Dodge W150 truck for decades. I purchased the truck new and these were the actual OEM factory installed plugs that I pulled out of the trucks 318 CID V-8 engine the very first time they were replaced, so have been using them ever since, except for the one time they weren't available at the local auto parts store and I ended up using the Autolite brand plugs they had in stock. The RN12YC plugs have worked well in my vehicle over the years and even now with an old, high mileage engine I'm getting decent performance with them and a set of these plugs will last through several years of driving before needing to be replaced. These plugs were very reasonably priced here on Amazon as well, so overall I'm very happy with the purchase.

### ⭐⭐⭐⭐ Reliable for decades
*by M***Y on May 25, 2022*

Same plug, same look, same great performance I've been used to for decades. Fails to get 5 stars only because of the indestructible plugs now made but for power equipment and applications on older cars this is the only plug I'll use.
