Nova Engines Turbo Glow Plugs

Keep your nitro mill screaming at peak RPMs with the exact ignition timing you need, no matter the track conditions.

Engines like the powerhouse Nova JW12 ship from the factory with a standard No.5 plug because it sits perfectly in the middle of the heat range—making it the ultimate go-to plug for most racing conditions. But as ambient temperatures swing, track layouts change, or you start experimenting with head shims and higher nitro percentages, you need the right plug to keep your tune dialed. You don't need to completely overhaul your tuning strategy; you just need the correct variant.

Nova Engines now offers their legendary Turbo Glow Plugs in three specific heat profiles to match your exact racing needs. All variants utilize a precision-tapered "Turbo" seat to create a flawless, leak-free seal with your engine's head button, maximizing compression and power output.

The Variants

• No.5 HOT: By enlarging the opening around the filament, more wire is exposed to the fuel mixture. It effectively advances ignition timing to eliminate bottom-end bogging in cooler or damp conditions.
  
• No.5 Standard: The factory replacement for your JW12 engine. This is your reliable baseline plug for stable idling, clean mid-range power, and consistent top-end performance in typical weather conditions.
  
  
• No.6 Cold: About as cold as you'll ever want to go for off-road racing. This is the ultimate plug for massive, wide-open tracks where you are pinned at WOT (Wide Open Throttle) for long stretches. It's also the required plug if you are running a highly compressed tune with a very thin head shim stack and 30%+ nitro content.
  
  
• If you're not sure: Choose the No. 5 Standard plug! This plug works perfectly in nearly all conditions!
