I ended up just buying the plugs from Sewell Lexus Parts for about $100. My buddy and I hammered it out ourselves in about 3-4 hours. Took our time to make sure it was done right. I can hook you up with my mechanic buddy if you want. He lives in North Phoenix. He'll probably do it for less than half of what dealer wants.
DAMN ! What are they doing to the car at 60k to justify $2100 !!! Thats crazy. I am assuming they are servicing the differential, cooling system, engine, oil, ......? not sure how they can justify that kind of cost .

I wonder if it would be cheaper to take it to a Toyota dealership. My concern is someone messing something up when working on the car because they are unfamiliar with the car.

There is not much to it really. Any decent mechanic will do. Tell them in advance that they will need to remove the battery for easier and quicker access to the rear plugs

Hey guys I think Im going to to try this when it comes my time ( in 29k miles lol ) I found a 60k kit on sewell thhat has all of the parts that need to be replaced for a fraction of the cost. Just buy the 60k service kit from them and then have the dealership do the labor for the essential stuff.....if you want to go to the dealership. If not , like many have said, have a good mechanic do it but you can still use the oem parts

http://is.sewellparts.com/accessorie...2012/2095.html

kit with CL membership drops to $187.20 !! and that includes

Oil Filter and Drain Plug Gasket
Air Filter
In-Cabin Microfilter
Brake Fluid
Spark Plugs

even if you have them replace the differential fluid its still going to be a hell of a deal

you are welcome

I'm not ready yet, but when it's time I'm going to do it myself. I will stick with Denso, but I've been doing some research and found there are two other Iridium plugs in addition to the OEM FK20HBR11 that Denso makes for Toyota vehicles.

They are:

1. The IKBH20TT, a Iridium Twin Tip series plug that seems to have many advantages over the stock plug, however it's much cheaper

http://densott.com

2. VFKBH20, a Iridium Tough series plug that is supposed to maximize performance. But, this plug seems to be available only in Europe and Japan

Thanks for the leg work, Lou. I would like to upgrade when I get to that point, but sounds like we may not have many options.

Going to give these a try. Just ordered a set through Advance Auto Parts + promo codes, turned out to be a little over $50. Thanks Lou for doing the research.

I wouldn't bother messing with different plugs unless you are spraying. The OEM plugs work really well and they last the full rated service life even when occasionally asked to deliver full performance. Anything else is a crapshoot, not an upgrade.

I'd tell a long story about how I bought these super whamodyne spark plugs and they died in 600 miles, but I think you get the picture.
