Honestly I would just stick with OEM. I *think* they are Denso.

Your year should be Denso IK20 Dual Tipped Platinum. If you want to go Iridium get the OEM Denso Iridium SK20 for you 1MZ-FE.

Default 2000 RX300 Spark Plugs

Get the Denso Iridium plugs. They cost more but you'll probably never have to change them again! The NAPA store has them for about $6.00-$8.00 each. The Lexus dealer charges $20.00 each [ plus labor ] for the same plug.

Stick with Denso.

I know a few friends that have tried NGK and the Torquemasters, but went back to Denso.

Just a reminder. Get the OEM Toyota/Denso Iridium SK20 which can go up to 90k...not to be confused w/Denso "Hi Power" Iridium IK20, which only last up to 30k.

When I went up to my dealer in San Antonio, they did put in the sk20s, even saw the box. Cannot remember what they charged, but doing the labor yourself was a pain from what I recall, i.e., the throttle body.
