FAQ
Is this spark plug compatible with all Polaris RZR models?
The MR9F is specifically designed for the RZR Pro XP, Turbo, Turbo S and Turbo R models produced between 2017 and 2025. It matches the OEM part number 3023173, ensuring a perfect fit for those vehicles.
Can I install the plug myself?
Yes. The plug uses a standard M14x1.25 thread and comes with a pre‑gapped electrode. With basic hand tools and the torque specifications provided in the vehicle’s service manual, most owners can complete the installation in minutes.
How does the copper material benefit performance?
Copper offers excellent electrical conductivity, which helps produce a strong, consistent spark. It also dissipates heat efficiently, reducing the risk of pre‑ignition and extending the plug’s service interval.
What is the warranty on this spark plug?
Quad Logic provides a one‑year limited warranty covering defects in materials and workmanship. If the plug fails within the warranty period under normal use, we will replace it at no cost.
Do I need to replace both plugs at the same time?
While it is not mandatory, replacing both front and rear plugs simultaneously ensures balanced performance and prevents uneven wear, which is especially important for high‑performance UTV engines.
