spark plugs
just wondering what the latest 2011 spark plug innovations everyone has heard of. I currently use the Bosch FR6LDC, but am going to probably get me a new set before summer and was wondering what the general consensus is for plugs currently.

The plugs that I know of currently in use or recommended are:

Bosch FR6 LDC
denso PK20PR-P8,
NGK BKR9EIX iridiums

what about denso iridiums:
IK20- heard bad things about these, but that was some time ago
SK20PR-L11

I have used denso PK20PR-P8 for the past few changes with good results. Although I have no complaints with Bosch FR6 but have not used them since the car was over about 500 whp.

I use the EPL recommended NGK BKR7E (copper) plugs... We'll see how their tune likes it when my car goes back together.

I think the reason is most people are still running on FR6 and have no experience with Denso P. yet.

I use none of the listed plugs. You need to find work works for your motor. Heat range will change a whole list of things. afr's, exhaust temps, response. Just to name a few.

..I just put the Denso PK20s in ...The only thing I have noticed,is that my idle stayed at the same RPM speed as before the swap But it fluctuates a very little bit up and down[sway] at the same RPM increments.Before with the Bosch plugs,it was rock steady......I had 10,000 miles on the Bocsh,they looked great and I hit 1.4 bars in the cold weather here with no problems..
