If you have changed the spark plugs in your rx330.


what are some tips?

can it be done without taking apart windshield wipers and associated trim?

can it be done without taking the plenum?

Let us know how you did it and if you have any tips.

Tips: Denso or NGK Iridium plugs only. Have lots of time and tools available. Easily took me 3 hours.

Can be done without taking wipers and wiper assembly off.

Personally I see no way it can be done without taking the plenum off. Plus you can clean and change gaskets while in there.

There is a guide floating around here if you search it. I forgot which user but there's a link on it to the PDF, really helpful.

I posted a excellent video in this thread, it shows exactly what you are facing for the task:

thanks.. i saw that video...but is the es330 different in terms of space compared to the rx330 s space. same motor but just wondering what peculiar
things are involved with the rx330. there are no videos that are from a rx 330. but it sounds like if the plenum can be removed without taking apart the
windshield wipers and associated trim. then it will be just like doing the es330.

Having a ratcheting wrench (gearwrench) with a flexible head makes getting to the bolts behind the upper intake manifold a lot easier. I believe they are 12 and 14 mm
