Unleash Maximum Power: NGK R7438-9 (4656) Racing Spark Plug

Are you running a tuned engine? When your high-performance motor is running Stage 2, Stage 3, or higher, you need an ignition component that's up to the job. The NGK R7438-9 (4656) Racing Spark Plug is expertly engineered to handle the extreme heat and pressure of modified engines, delivering a fierce, reliable spark to prevent misfires and ensure you get maximum horsepower.

Why the NGK R7438-9 is Essential for Tuned Cars

This spark plug is the choice of professional motorsport teams and serious tuning enthusiasts across the UK and beyond, built to thrive in the harshest thermal and mechanical environments.

• Reliable Ignition: It features a Fine-Wire Iridium Centre Electrode coupled with a Platinum Ground Electrode. This precious metal combination ensures an ultra-stable, consistent spark, even when facing high boost pressures and high cylinder temperatures.

• Combat Misfires: This colder-grade plug is a common and necessary upgrade for many popular tuned platforms (such as the VW/Audi 2.0 TSI EA888 Gen 3) to prevent the dreaded spark blowout that leads to misfires under load.

• Built to Last: The Iridium Alloy has an exceptionally high melting point, making it perfectly suited for the intense operating conditions of modern, high-output engines.

Performance Features:

• Special Insulator Design: Improves throttle response and significantly resists fouling.
• Trivalent Metal Plating: Provides superior resistance to corrosion and seizing—meaning you won't need to apply anti-seize compound.
• Copper Core: Aids in rapid heat transfer away from the tip, protecting the plug and the engine.

Don't let a standard plug hold back your tune. Upgrade to the NGK R7438-9 and get the performance you paid for!

(Please note: These racing plugs come accurately pre-gapped. The ground electrode is delicate, so it's best not to attempt adjustment. Always consult your engine mapper or tuning expert for the correct plug specification.)
