I have had experience with Torquemasters and Densos (current) in my 99 RX. I am going to swtich to the Iridium IXs. I would love to go with those, V-Powers, but they are copper and won't last according to my racing buddies.
From what I have read, the IXs will give you a better performance and a slightly longer service life and the OE Lasers.
