I think I will get better gas mileage along with better performance with the new plugs. Also they reccomend not gapping them because the irridium center electrode is more brittle than most metals and can be fractured or broken. I dont see a safe way of regaping them to bring the spark plug gap back in tolerance due to the design. These plugs were engineered with very thin and pointed metal for the electrode, maybe thats is why they call them Laser.

When I pulled the plugs today at the above mileage, the gap was off significantly due to the wear of the plugs and the electrode was pretty warn. I also noticed hard acceleration performance might indicate a spark plugs issues. I noticed my 2016 Outback limited 2.5i was not idling as smooth as it could at 61,311.

In line with ’s long-standing ethics policy, editors and reviewers don’t accept gifts or free trips from automakers. Play it safe by checking the maintenance schedule and following the manufacturer’s recommendations for your vehicle.Ĭars.com’s Editorial department is your source for automotive news and reviews. However, there are limits even for iridium-tipped plugs, and some manufacturers, such as Toyota, warn that not replacing them on schedule can void the emissions warranty. When manufacturers say that maintenance such as replacing spark plugs should be done only every 100,000 miles or longer, many vehicle owners think of them as lifetime parts. Unless the engine is performing poorly, replacing the plugs ahead of schedule might not produce dramatic improvements and the cost could outweigh the benefit. Even under those circumstances, the cause could lie elsewhere, so it’s better to have a technician diagnose the problem instead of reflexively replacing the plugs.Īfter 75,000 miles or more, spark plug electrodes might be worn or there might be light deposits on them, but the electronic engine controls will adjust the air-fuel mix and spark timing to compensate, so there probably will be only a slight loss of performance or fuel economy, if any. The only reason to replace plugs more often than recommended is if the engine is hard to start, idles roughly, hesitates, misfires, uses more fuel than usual or if the check engine light comes on. Now, though, there is no such thing as a tuneup. Spark plug replacement used to be an integral part of periodic engine “tuneups” that 50 years ago were necessary as often as every 5,000 miles. On some Mercedes-Benz models, it’s as frequent as every 36,000 miles, but on others, the intervals are longer.

The plugs on BMWs such as the X3 and 3 Series should be changed every 60,000 miles. If a vehicle frequently tows a trailer or spends a lot of time in stop-and-go traffic or idling, then Ford suggests installing fresh plugs every 60,000 miles. Ford advises to change the plugs at 100,000 miles on an F-150, Explorer and other models under “normal” driving conditions.

How Often Do You Need to Change Spark Plugs?īecause manufacturers use different kinds of spark plugs, the best guide as to when they should be replaced is the maintenance schedule that comes with every vehicle either as part of the owner’s manual or as a separate guide (they can also often be found online).įor example, Toyota recommends changing the plugs every 120,000 miles on a Corolla, RAV4 or 4Runner, but every 60,000 miles on an 86 coupe, which was developed with Subaru and uses a Subaru engine. The spark plugs in many vehicles today have iridium or platinum tips on the electrodes (the parts that transmit the spark) that last longer than conventional plugs with copper and nickel-alloy electrodes. That longevity is a product of the electronic controls that precisely manage the air-fuel mixture and when the spark plugs ignite that mixture, as well as improvements to the plugs themselves.
