Glow Plugs & Spark Plugs | RC Glow Plug (Afterpay)

High-quality RC glow plugs and spark plugs for your radio-controlled vehicles

Premium glow plugs and spark plugs are essential for all nitro enthusiasts. Every RC engine needs oxygen, fuel and ignition to run — an RC glow plug provides the ignition to nitro engines, while an RC spark plug ignites gasoline-based internal combustion engines by heating a small coil within the plug known as “the element,” which safely ignites when heated.

While glow plugs are simple to use and easy to install, many nitro enthusiasts are still unsure of how to choose the best RC glow plugs and spark plugs for their vehicles. Using the incorrect glow plug in your engine can damage your RC vehicle. We always recommend consulting the manual provided with your vehicle and the instructions on each set of glow plugs to determine which one will give you the best performance.

Choose the right RC Nitro Glow Plug for your vehicle with Frontline Hobbies and maximise your performance

Selecting the right glow plugs and spark plugs for your RC vehicle will depend on the size of your engine and the type of fuel your vehicle uses.

In general, smaller engines need hotter plugs like the OS Engines P3 Ultra Hot or the Alpha Platinum N4 Medium Hot glow plug. Larger engines require colder plugs like the Alpha Platinum N6 Cold or the Alpha Platinum T8 Super Cold. We also stock standard-size glow plugs like the LRP Platinum R5 for mid-sized engines.

You also have a choice between standard plugs and turbo plugs for your vehicle. Standard plugs give you reliable results and are the glow plug RC users prefer for everyday driving. Meanwhile, turbo plugs provide less compression leakage, which boosts your vehicle's performance by giving it more power.

You can mix and match between standard and turbo glow plugs depending on your needs. Turbo plugs like the LRP Turbo Style Platinum Glow Plug will give you better performance for a shorter period, so we recommend them for races or special events. For everyday use, standard plugs like the LRP Platinum T4 will last longer and are more affordable to replace.

Stock up on RC spark plugs and glow plugs to make sure your vehicle is always ready to race

The lifespan of an RC nitro glow plug is determined by how often you use your vehicle. Some glow plugs can be used for months, while others will only get you through a single tank of fuel depending on how aggressively you drive. While there’s no hard and fast rule for how long a glow plug should last, you’ll notice a dip in performance in your RC vehicle when your plugs are getting worn out.

We recommend checking your RC nitro glow plug before each use to make sure they’re still glowing brightly. If your plug is dull, it needs to be replaced. For racers, we suggest installing a fresh set of brand new glow plugs and spark plugs before every race or special event. Trust us — you don’t want to realise that your glow plugs aren’t up to snuff mid-way through a race!
