It is totaly up to you the stock(iridium)plugs are good for 100,000miles. I changed my plugs to NGK TR55's it smoothed out the idle quality thats about it.

My 06 C6 was part of a test for Pulstar plugs.

They ran the car on a dyno. It had 27,000 miles on it at the time.

The put the Pulstar plugs in and ran it again. Lots of cool down time and the same atmospheric conditions. I picked up 7 RWHP with the Pulstar plugs.

They fire off quicker and the engine registers knock and pulls timing because the flame front travels faster. You get more complete combustion which gives a bit more power but the timing can't be tricked/tuned out of the computer. So you lose some of the advantage from the faster more complete combustion.

Here's the real kick in the nuts, they put in NGK TR55 copper plugs. The car gained 3 hp over the Pulstar plugs.

The $1.99 copper plugs produced more power than the $25.00 trick plugs.
