How to Replace Spark Plugs on a Toyota Corolla 2003-2008

If you’re hands on and have some basic tools, consider changing your own spark plugs every 100k miles to keep yourself on the road with good mpg. You’ll just need basic tools and about 30-40 minutes. Doing this job yourself will save you about $400. Since you’re doing it yourself, go for quality and buy iridium or ruthenium, too. Parts below are for the CE, LE, and S trims. They should work for the XRS but double check before buying.
