High-Performance Car and Truck Spark Plugs

Sonic Spark Plugs are PRE-GAPPED, so you simply need to take out the old plugs and put in Sonic Spark Plugs. **Please note: Sonic Spark Plugs are more efficient than conventional plugs, so your vehicle's on-board computer will need to be reset. To do this, simply disconnect both leads to your battery and touch the leads together, which will reset the on-board computer.

1. Mechanic - It is usually pretty simple job to have your mechanic install Sonic Spark Plugs, and not expensive. Your mechanic can install the plugs at your next scheduled tune-up.

2. Factory Service - Often times, factory service will discourage you from installing new plugs, telling you that your plugs are good for either 50,000 or even 100,000 miles. Some factory service stations may even tell you that installing these plugs will void your warrantee. As ruled by the United States Federal Trade Commission, and the Magnuson-Moss Warranty Improvement Act, a vehicle manufacturer may NOT make its vehicle warranty conditional on the use of any brand of spark plug.

3. Do It Yourself - Easy. Like screwing in a tiny light bulb with a socket wrench. If you're reading this, you've done it before.

Where is the extra performance usually felt?
It depends on the type of vehicle. V-6 and V-8 engine can expect to feel the extra power at lower R.P.M.s. If you have an inline 4 or 6, expect the power more toward the upper-range of your tach.

Why are these more expensive than regular plugs?
Sonic Spark Plugs have a lot of extra quality-control and handwork. They are made in process that requires many more steps than conventional spark plugs.

How are these plugs made?
We start out with premium Autolite and NGK brand spark plugs, and modify them with our patented process. But before they are modified, they are put through a second battery of quality-control checks, since not all spark plugs are precisely-manufactured enough to handle our modifications. Then the plugs are carefully adjusted, machined and custom-modified to work optimally with every customer's vehicle. Your spark plugs get a lot of attention before they end up in your car or truck.

Can I expect to see Sonic Spark Technology is anyone else's spark plugs?
Maybe. We work closely with key spark plug manufacturers, and some of them are waiting for the right time to exploit ultrasonic spark technology. If you haven't seen it yet on the big guy's products it's probably because the large companies have to wait until more buyers understand ultrasonic plugs. But by buying through Sonic Spark Plugs, you can have tomorrow's technology today.

Are they safe for my vehicle?
Safe as a regular plug. Why? Because unlike other high-performance plugs, we don't modify the spark, we only add the ultrasound. So your spark won't be any hotter or longer than the factory specifications. We have found that the major spark plug manufacturers are very careful about manufacturing plugs that are safe for your vehicle. We don't believe in deviating from their specifications.

Are they difficult to install?
Depends on the engine. Some engines are easy, some are a little harder, but Sonic Spark Plugs install like regular plugs. If you have any difficulty, your auto technician will be able to readily install them. When installing on newer, computer-controlled engines, disconnect the leads to the battery and touch them together. (Warning: Be careful not to short the battery!) This will force the on-board computer to reset, because Sonic Spark Plugs have a different performance characteristics.

Will I need to retune?
Depends. If your engine is carbureted, and needed a tune before you put the spark plug in, a tune will help. If your engine is already in tune, you should be okay when you install Sonic Spark Plugs, but sometimes, you might find that tweaking your air/fuel mixture may give better results.

Why are they factory-gapped?
After twenty years of experience developing Sonic Spark Plugs and installing them in a variety of different vehicles, we've found that slight variations to factory-specified gaps, often produces better efficiency. We've also found that slight variations can help improve performance for different areas of the country, depending on altitude, and the type of gas additives (MTBE, alcohol) used.

Whoops, I dropped a plug before I installed it. What now?
You can send it back to us, and we'll make sure it's adjusted properly, or you can set the gap to the same gap as one of the other plugs.

How can I purchase?
Call us on our toll-free number. Your plugs will usually ship within three days, and arrive to you by U.S. Priority Mail.

If these plugs are so good, why haven't I heard of them before?
Two reasons, first, it is extremely expensive to launch a global release of any automotive product. We started out small, and have been growing ever since. Second, some of your friends may already use Sonic Spark Plugs. We're one of the best-kept secrets around, because lots of drivers don't want their "competition" to know their secret ... that a quick spark plug change can offer a performance upgrade.

When do you start with NGK or Autolite plugs?
Generally, the Japanese vehicles use NGK, and the U.S. and European vehicles like Autolite. But both plugs will generally work fine in either type of engine.

Are the heat-ranges the same?
Yes. That's what makes our plugs so safe in your engine. Unlike other high-performance engine parts, we use factory settings. Sonic Spark Plugs give your vehicle more power by increasing its efficiency, not by pushing it harder than it was designed.

How will my vehicle ride and feel differently when I install?
It depends how you drive. Some people like power, some like mileage. Some engines have lots of carbon deposits in their cylinders, so they will not feel an immediate effect. But after Sonic Spark Plugs clear out some of those carbon deposits, their power will usually go up.

My car's engine isn't in great shape. Can Sonic Spark Plugs help me?
Sorry, our plugs are designed for well-tuned engines. Put them in a defective engine and you will not see a difference, except that you will quickly foul-up a new set of plugs.

What about Platinum and Titanium plugs?
We used to use Platinum plugs, but we discovered that the conventional metal gives the best results for most applications. This is because conventional copper-alloy oxidizes just a little bit, which makes for the ideal conductor. Platinum is long-wearing, but for people who take good care of their vehicles, we recommend conventional copper-alloy plugs. Titanium is also good, but a bit untested.

What about Split Fire^TM, Bosch^® and other high-performance plugs?
They're decent plugs. But they can't do what Sonic Spark Plugs can do, because they don't have our patented ultrasound yet.

What guarantees and warranties are on the plugs?
30-day money-back guarantee on the plugs. No other warranty is implied or expressed.
