Most Liked Negative Review
Items good Service wasn't.
The plugs were great . I ordered online the night before I went to pick them up. It said they would be ready to pickup in 30 minutes that night, but I went in the next morning and had to wait on them to pull my online order . That added 7 minutes to my time in the store. Don't say it will be ready to pickup if your going to pull it when I get there. If I would have known that I could have went to store got my plugs and paid. then left. That what online ordered is about shop, pay and pickup .

Does this plug fit a 2010 Dodge Journey 3.5 motor
Verified Reply - Steve
Hi Jerry, I'm glad to help you! This Champion Copper Plus- Single Card - RC12YC (Part # 71-1) does not fit your 2010 Dodge Journey. We do have an exact spark plug available online for your vehicle and the part number is 7034. Please enter your vehicle on our website and search for this part to check the fitment.
will this work for a poulan pro 25cc leaf blower
Verified Reply - John the Car-Doc
Hi Don, I'm glad to assist you! This Champion Copper Plus- Single Card - RC12YC - Part # 71-1 is not specially made for your Poulan Pro 25cc Leaf Blower. The type of spark plug varies from unit to unit for Poulan Pro. Most of their blowers use Champion Copper Plus Small Engine- Boxed - Part # 863 (RCJ8Y) or 852 (RCJ6Y). Please follow the spark plug recommendation and replacement procedures in the operator's manual if you are doing the work yourself.
I need to replace sparkplug in my john degree riding mower s180 model. It had champion xc92yc sparkplug, will this work?
Verified Reply - John the Car-Doc
No, Tracy. This Champion Copper Plus Small Engine- Single Card - J19LM - Part # 861-1 has a 3/8"-inch reach, 13/16"-inch hex size, and heat range of 19. While the Champion Copper Plus Small Engine- Boxed - XC92YC - Part # 980 has a 3/4"-inch reach, 5/8"-inch hex size, and heat range of 92. You would have to match one by size to what is on your John Deere S180 Lawn Tractor that can be fabricated into its place.
