Spark plugs
Which spark plugs do yo guys use? Recommended is NGK iridium,but is it the only way to go? What about Autolite or Denso spark plugs?

Use OEM. I bought mine from Seeell Lexus with our discount. Best deal around and you can't go wrong.

I used the OEM too, and I don't see a reason for switching to anything else. It's what the engine originally came with and 99% of us aren't doing any heavy engine mods, so they are really all you need! lol

I used the cheaper Bosch double tips, in my GS 300, and my idle was never as smooth. Gone OEM since and haven't had a single hiccup.

Don't use an Autolite plug in anything other than a lawnmower. Stick with OEM.

OE plugs from Sewell is the ONLY way to go. Factory plugs are Nippondenso, if I'm not mistaken. I got mine from Sewell for about half what my local Lexus and Toyota dealers wanted for them. Lexus wanted $25 per plug, Toyota told me $20. Sewell charged about $13 per plug plus shipping.
