First time poster, but been using the site as a resource for awhile. I just 100K on my runner and decided it was time to do some of the maintenance (coolant, tranny flush, etc. etc.) any way I searched on here and found like 100 spark plug posts and decided that I'd go with the Iridiums. Well I pull out the plugs that have been in the truck for the last 20K+ miles.
Thing is I don't think they affected performance in any negligible way despite being way too short. I passed the CA Smog test with flying colors and the truck has never thrown any codes or had any misfires.
No clue when or where these were installed but it was before I bought the truck.
I wouldn't be surprised if it was some halfassed dealer somewhere. The people here at Sunnyvale CA toyota tried telling me I had "World Standard" tranny fluid and had to have the service writer inspect on the hood and prove it had a dip stick reading "Type IV" and was not a WS tranny...
