It’s gotta be done
It’s about that time when Toyota recommends the replacement of spark plugs, typically when your vehicle reaches 120,000 miles. There are some benefits, but it’s safe to say this falls within routine maintenance and can be very costly. The dealer I talked with had proposed $900 for the job, which seemed unreasonable for a set of cheap spark plugs. Let’s look through the work that is required and you can make the decision for yourself.
Having done this before, this should serve as a helpful guide for those of you in the same predicament. There really isn’t any need to disassemble a large part of what’s under the hood. This guide will focus primarily in on getting the spark plugs replaced with the least amount of work required. Estimation is 2 to 4 hours, but will require a long reach and strong nimble fingers.
