Decided to replace my spark plugs, but was told it was a big job on GS models. Lexus, Toyota, and two other shops quoted me $500-$600 and said it was a 4 hour job. I was able to change them in 30 minutes at home! The passenger's side was easy, after removing air intake. Driver's side was a little tight, but I only needed to unclip the wire harness to get access. I used a 12-inch socket extension to reach through any obstructions.

Its because most people don't have the know how, tools, or desire to work on their own car.

In theory, it's supposed to be a difficult job, which is why I visited four shops before doing it myself. EVERYBODY said that it takes 2 hours just to access the plugs. I'm wondering if the 2nd generation GS300 was more difficult? I'm posting this because I couldn't find anything online about it, although there are many threads on other models which claim to correspond to the 3rd gen. GS300. Maybe the shops follow more stringent protocols, by removing all wire harnesses and obstructions?

The 2gs you have to remove the throttle body to access the plugs but it's not overly difficult, surprisingly on my gs460 the Lexus dealer did my plugs for 300 which I thought wasn't bad, I couldn't find anything on doing them on a 460 and I wanted to do them when I got the car just to know they were done.

The 3rd gen is much easier and quicker. I have done both
