Folks,

On the surface an RX330 Spark Plug replacement DIY looks very difficult. However, in the RX300 (First Gen) boards, there is a great DIY that shows how to remove a throttle cable and brace and the PCV valve and tube, and the back 3 plugs can be accessed.

It shows how to use 2 smaller ratchet extenders (apparently the technical term is 3/8 and 5/8 where I would of called them 3" extenders), and that allows you to safely get to the spark plug and have enuf strength to loosen the plugs without using the standard 6" extender.

Have any of you tried this? Are there any parts in the RX330 that will still block access that weren't in the RX300?

I've uploaded a few pics from Lexmex's post where he shows the parts removed.

I have $200 riding on this being possible to do on my own, versus having to take to the dealer.
