Spark plug removal

[Wibs]

Hi, to change the spark plugs for the 08 H2 is it a simple or a complicated procedure ?

An independent shop is giving me an estimate of 2.5 hours of labour needed to replace the spark plugs.

Any thoughts ?

Thanks

Book time is 1.8 hrs so they are a little high. Most difficult part is #8 plug, hard to get at. Can be done in less but as a flat rate tech i go by the book.
