Is it possible to replace the spark plugs on a 2006 Avalon without removing the manifold? Not sure if I want to tackle that at the moment. Looking at my Avalon and comparing it with the post “DIY 2GR-FE V6 Spark Plug Replacement” it would seem like there is a lot more room after removing the wipers and shelf on the Avalon compared to the Highlander in the post.

Has anyone done this without removing the manifold and is it possible with standard tools including the socket for plugs?

If you must remove the manifold then what would be a fair price to have a shop do it? It’s been 5+ years since I have had any work done in a shop.

I'm planning on doing the job soon, as the #1 coil on my car is kicking a CEL. There's a pretty good video here that captures the procedure as well as the tools required:

I've done the job on a couple of cars with transverse V6 engines but the Avalon requires the most parts removal for access compared to my other vehicles. Accessing the rear bank without removing what's shown in this video looks pretty difficult.

The DIY mentioned in the opening post of this thread is the best I've ever seen. It could that be more videos have appeared since I changed plugs on my '06 Avalon in June of '13.

If you wish to try to do a spark plug change on an '06 Avalon w/o removing the plenum(mistakenly referred to as manifold), go for it.

As far as I'm concerned, the ONLY way to do a plug job on this yr/model is to pull the wiper cowling and plenum like sweeneyp did in his write up. You'll have much greater access and will therefore be far less likely to break things.

I would suggest that you do the front row first; then start engine afterwards to ensure all is well. If you don't, then you'll not know which bank has an issue if the engine is not running right after the plug change. Spray electrical connectors first with brake parts cleaner; then some silicone spray to lube in the hopes the connectors don't break when you pull them apart. They may do so anyway. I broke 2 up front and used self-fusing tape to secure. 3 yrs. later - all is well.

There are all kinds of web sites with parts diagrams that can help with automotive maint/repair tasks. I like this one. Best to provide VIN when you access site to narrow things down.

Exactly the way I do my tune downs. Even more so when spark plug wires are being replaced.
