When you go to start your lawnmower, you expect it to spring to life on the first crank. But sometimes even a well-maintained mower can be difficult to start, rough-running, and excessively gas-guzzling. Why? Blame it on poorly-performing lawn mower spark plugs. Performance spark plugs can make the difference between a reliable lawn mower that never lets you down and one that leaves you hanging.
Lawn mower spark plugs that boost performance
High-performance spark plugs aren’t just for race cars and motorsports. Small engines also rely on a spark to combust fuel, in fact, small engines are highly sensitive to spark plugs underperforming. Pulstar lawn mower spark plugs provide faster starts and last much longer than conventional plugs. The ultra-high intensity electrical discharge our plugs deliver gives you more power and a quicker throttle response. The precise timing of our spark plugs keeps small engines purring along happily, giving them more stability and a longer lifespan.

High-performance Pulstar lawn mower spark plugs save fuel
High-quality lawn mower spark plugs do more than just keep the engine running smoothly–they improve fuel economy. Pulstar plugs use a unique combustion technology that results in the most rapid, consistent, and complete burn of fuel possible. The increased efficiency means that you get more power and waste less fuel on each mow. Whether you’re using a push mower or a riding mower, running out of gas mid-mow is a hassle. When your machine is using gas more efficiently, you can’t help but notice the difference.
Save time and money with the best lawn mower spark plugs
The less time you spend replacing plugs and struggling with a sluggish, hard-to-start mower, the more time you can spend on productive, uninterrupted mowing. Pulstar spark plugs can save you maintenance time by keeping your mower running when you need it. What’s more, performance lawn mower spark plugs can save you money on gas by eliminating waste.

Cut your emissions as you cut your lawn
Small engines are notorious for high levels of emissions. However, much of this is due to inefficient fuel use caused by poor engine performance. When you use Pulstar high-performance lawn mower spark plugs, your mower burns fuel more completely, resulting in reduced emissions.
Frequently asked questions about spark plugs
How often should I replace my spark plugs?
For best results, you should replace your spark plugs every 50,000 miles under normal driving conditions.
How do I know if one of my spark plugs is fouled?
If your engine misfires, idles roughly or doesn’t run smoothly, one or more of your spark plugs may have become dirty or fouled. Other symptoms of a fouled spark plug include a lack of acceleration, reduced gas mileage and difficulty starting.
Do I still need to gap spark plugs?
Pulstar spark plugs should be gapped to the setting recommended by the engine manufacturer up to 0.055” (1.40 mm). Do not gap greater than 0.055”. For factory turbo or supercharged engines, gap Pulstar spark plugs to 0/025” (0.63 mm).
What happens if I don’t gap the spark plugs correctly?
An engine with spark plugs that are not gapped correctly will not run smoothly and may not have power or misfire.
How often should I replace my lawn mower spark plug?
Lawnmower spark plugs are typically replaced once a year.
Does it help to clean spark plugs?
Spark plugs cannot be cleaned enough to operate as new. It is always best to replace fouled or contaminated spark plugs.
How do I install Pulstar spark plugs?
Pulstar spark plugs install the same way conventional spark plugs are installed. When using a ratchet and socket or similar tool, care should be taken to not put a side load on the ceramic.
What kind of performance benefits can I expect when upgrading to Pulstar spark plugs?
Customers see significant improvements in engine torque, horsepower, fuel economy and emissions. They notice quicker throttle response, smoother operation and improved towing capacity.
How do Pulstar spark plugs produce these performance benefits?
The science underlying our technology is sometimes called pulse power: energy accumulated over time is released quickly producing a very high power event, i.e., a pulse. Our patented technology applies this concept by embedding in Pulstar spark plugs a capacitor to store ignition coil energy prior to discharge, and to drive an ultra-high current channel across the gap when released. That powerful current creates an electromagnetic field that expands through the combustion chamber and ionizes the fuel air mixture, allowing the flame kernel to grow much more rapidly than in a conventional spark plug ignition event. The result is the most precise, powerful, consistent and complete burn possible.
Do you guarantee these performance benefits?
Yes, we do. If you aren’t completely satisfied with your Pulstar spark plugs, return them, together with your dated sales receipt, to the merchant from whom you bought them within 30 days for a full refund of your purchase price.
Do Pulstar spark plugs come with a warranty?
Yes, they do. If your Pulstar spark plugs prove to be defective in materials or workmanship within one (1) year of purchase, return them, along with your dated sales receipt and an explanation of the reason for the return, to Pulstar LLC, 2451 Alamo Avenue SE, Albuquerque, New Mexico 87106 and Pulstar LLC will replace them.
