NGK RZR XP Turbo Lower Heat Standard Spark Plugs

Protect your boosted engine against harmful detonation and pre-ignition! Engineered specifically for 2016–2021 Polaris RZR XP Turbo models running increased boost or performance ECU tunes, this colder heat range spark plug set is an essential reliability upgrade for high-horsepower builds.

From the factory, 2016 RZR XP Turbo models come equipped with hot spark plugs that can create hot spots inside the combustion chamber under higher boost pressures—leading to dangerous knock or detonation. While 2017 models received cooler factory plugs, their longer reach protrudes deeper into the cylinder. Transitioning to this shorter, colder heat range plug design runs cooler inside the combustion chamber while preventing hot-spot ignition, protecting your pistons, valves, and head gasket.

All spark plugs are pre-gapped to AA specification for optimal flame propagation and reliable spark kernel development under elevated cylinder pressures.

Features:

• 1-Step Colder Heat Range: Rapidly transfers excess heat away from the plug tip to prevent pre-ignition and engine detonation under high boost.

• Optimized Shorter Reach: Sits cleaner in the combustion chamber to reduce hot-spot exposure and protect against knock on 2016-2021 cylinder heads.

• Pre-Gapped to Precision Spec: Pre-set to AA's specific gap tolerance for high-boost applications, eliminating spark blowout under high load.

• Essential Tune Upgrade: Recommended add-on when running AA performance tunes, upgraded turbochargers, or aggressive pump/E85 fuels.

• Sold as a Complete Pair: Purchasing a quantity of (1) includes a set of (2) pre-gapped spark plugs—everything needed for a complete change.
