05.25.2009 · Posted in Home and Garden Articles

A great question that vehicle owners ask on a regular basis. But to make this little game of hide and seek as frustration free as possible, we’re going to point you to 3 simple areas. Your car, your owners manual, and, even if you’ve found it by that point, a great online resource to not only find the factory plug for your car, but every other spark plug available.nnIf I had my way, there would be a sticker under the hood of all my vehicles that lists the OE part numbers of every major component – light bulbs and paint color included. While they’re at it, a handy little mechanic that just hides under there and performs daily maintenance would be nice too. But since we don’t live in a perfect world, we have to go hunting for this stuff. nnSome vehicle manufacturers have kindly put the OE spark plug part number, yes, on a sticker even, under the hood, complete with recommended gap setting. But, if you’re in the same boat as me, and 90% of the rest of the world, your next stop is the owner’s manual. Don’t have the owner’s manual? I’ve got one more fabulous resource for you – and this one, you’re going to love!nnCheck out this cool tool at SparkPlugs.com – use the vehicle lookup to find your car. What magically appears in front of you is every spark plug available for your car by NGK, Denso, Bosch, Autolite, Champion, E3, Splitfire and Pulstar, complete with recommended gap settings. There will likely be some plugs that say something along the lines of “OE manufacturer or OE type”. If you know the brand of the original plugs in your car, just find that brands plug with that handy label. Those are the stock plugs. All other plugs with that label are the stock equivalent in other brands.nnWant more information on any of those plugs?

Looking for higher performance or gas mileage? After talking with some mechanics and spark plug techs we’ve learned 2 things.nn#1- Never downgrade. If the stock plugs on your vehicle are higher quality than traditional nickel plugs, the vehicle manufacturer likely used them for a reason. Some manufacturers are starting to see the advantages of using ‘high performance’ plugs. Others have had the spark plug manufacturer make that specific spark plug just for your engine. Downgrading to a cheaper/inferior plug could actually lower your engine’s performance or even cause engine damage.nn#2- Upgrading your plugs CAN increase your performance. Studies have shown that using ‘high performance’ plugs that are part of newer technology, such as iridium and fine wire plugs, can actually increase a vehicles gas mileage, horsepower and performance.nnHow can you tell what would be an upgrade vs. a downgrade? According to SparkPlugs.com, the list of available plugs is categorized according to a variety of factors that affect a plugs performance, resulting in a “good, better and best” sort of ranking, with the best plugs starting at the top.
