Denso Iridium Spark plugs

[drewXrunner]

Alrighty, I have my exhaust and headers installed, URD Supercharger is going on this weekend. I saw a tip on the instructions to run these IKH-22 spark plugs. Does anyone know if its a "must" to do this or will I be ok just running the stock ones. All info would be greatly appreciated. :rock:

Recommended not required. You can run the kit without them.

I bought them from Sparkplugs.com. Paid $71.70 + $7.84 shipping.
They are one step colder than the stockers, so it's not just a change of brand or material.

Hey Jon, you think I should get these for my truck, I never got them since I've been S'C'd?

Can you tell a difference driving with them, like more power or something?

I didn't really notice much power difference, but it may help some. I got mine mainly for the benefit of not having to change them for 90k miles

The ebay source was $56.90 including shipping to Hawaii. These were the iridiums for the v6.
