NGK Iridium IX Spark Plug for TVS Apache RTR 160, RTR 180, Victor GLX 125 & Fiero - Part No. CR7EIX

Ultra-Fine 0.6mm Iridium Tip: High-melting-point iridium alloy electrode guarantees precise gap retention and long service life.

Superior Anti-Fouling Design: Thermo-edge shell construction continuously burns off carbon deposits, preventing misfires during slow city crawling.

Trivalent Metal Plating: Provides excellent anti-corrosion and anti-seizing protection against severe engine bay heat and weather exposure.

Enhanced Acceleration & Mileage: Promotes complete flame propagation inside the cylinder head for maximum fuel efficiency and crisp throttle feedback.

Direct Fitment for TVS Engines: Factory-calibrated thread pitch and heat range designed for optimal operation across TVS 125cc–180cc engines.

Ignite your engine's true potential and experience instant throttle pick-up with the NGK Iridium IX Spark Plug for TVS Motorcycles (Part No. CR7EIX). Designed specifically for high-revving powertrains like the TVS Apache RTR series and reliable daily commuters like the Victor and Fiero, this performance spark plug features a laser-welded 0.6mm ultra-fine iridium center electrode. Requiring lower electrical voltage while focusing a hotter, precise spark kernel, it dramatically improves combustion efficiency, stabilizes idling, and reduces carbon fouling across all riding conditions.

Standard copper or nickel spark plugs degrade rapidly under continuous high-RPM running, leading to widened plug gaps, hard starting, sluggish pickup, and wasted fuel. Upgrading to the CR7EIX NGK Iridium IX spark plug restores instant push-button ignition, sharpens engine response, and ensures consistent combustion reliability.

Recognizing Spark Plug Wear & Failure Symptoms

Hard Cold Starting: Engine requires multiple starter button presses or kick-starts to fire up, especially during cold mornings.

Misfires at High RPM: Engine jerks or hesitates during aggressive acceleration or top-end speed runs.

Rough Idling & Engine Stalling: Unstable, fluctuating idle RPM when stopped at traffic signals, leading to occasional unexpected stalling.

Drop in Petrol Mileage: Increased fuel consumption caused by unburnt fuel exiting the exhaust due to weak or intermittent ignition sparks.

Heavy Soot or Ash Deposits: Carbon buildup on old plug tips indicating poor spark intensity or improper heat range operation.

Maintenance & Installation Best Practices

Avoid Adjusting Iridium Tip Manually: Do not attempt to bend or scrape the fine 0.6mm iridium center electrode with crude tools, as delicate iridium alloys can snap.

Hand-Thread Into Cylinder Head: Always turn the new spark plug into the cylinder head by hand for the first few turns to avoid cross-threading aluminum spark plug threads.

Proper Torque Setting: Tighten to recommended factory torque (10–12 Nm for 10mm threads in aluminum heads) using a 16mm spark plug socket; do not over-torque.

Inspect Plug Cap Seal: Ensure the rubber weather boot inside the spark plug cap is intact to prevent rain water penetration and high-voltage shorting.
