Best Spark Plugs For 2022

The best spark plugs for any engine are the same ones it came with from the factory and these AC Delcos were original equipment in one of the most popular and prolific engines of all time. General Motors churned out its 100-millionth small-block Chevrolet V8 engine in 2011 and didn’t stop there. Using original equipment replacement parts is a no-brainer, especially with a critical and inexpensive part like a spark plug.

Going with original equipment spark plugs doesn’t always mean paying the price for a trip to the dealership, and AC Delco (see above) isn’t the only game in town. Denso is a parts supplier to automakers worldwide, and all its aftermarket parts meet or exceed original equipment specifications. These Iridium TT spark plugs bring twin tip electrode technology Denso originally developed for high-end luxury and exotic cars to economy runabouts like a Ford Fiesta ST. The Iridium TTs are made for a correspondingly wide range of vehicles, so finding a part that fits is easy.

The E3 engineering team trains a laser focus on spark plug performance, and its patented Diamondfire ring electrode brings the advantages of a surface and conventional j-shaped electrodes together for improved combustion. E3 offers spark plugs for everything from passenger cars to lawn and garden equipment. So put a set in a Chevy pickup or try one in the old lawnmower and be the judge. 

Consistently high quality, a comprehensive applications catalog and time-proven performance make NGK an excellent choice for standard electrode and noble metal wire tipped spark plugs. NGK is an OEM supplier, and these standard copper core plugs were original equipment on most Japanese cars, SUVs and motorcycles from the 1960s to the 1980s, and we’ve used them for many years in older vehicles from other countries with no problems at all. If unit 7634 doesn’t fit your vehicle, check around for the other conventional NGK plugs, they’re all of high quality.  

Champion spark plugs power the world’s fastest cars and daily drivers alike with proven performance. Lawnmowers and garden equipment need maintenance too, and this best-selling Champion Copper Plus spark plug helps keeps small engines running their best. The standard spark plug is a springtime tune-up favorite priced low enough to pick up a few spares for subsequent seasons.
