Spark Plug Time!! What's best, where to buy...

OK so gonna change the Spark plugs in my Z as they have not been changed in over 11 years!

They have done well considering my Z has been and still is a daily drive all that time.

 

I'm thinking I would like some NGK PFR6B-11B's but where can you get them in this country or is it an order job from Z1 in America.

The only reason for this is I'm running 1.2Bar of boost on uprated Turbo's and understand the 11B's are a little longer than the NGK 11C's or any other plug.

 

The Z Centre offer NGK Iridium's but are these better, offer any benefit or should I just stick with PFR6B-11B's as they we're specially designed for our engines...

 

What Plugs is everyone running with uprated boost on here and what do you recommend please?

Iirc 11bs were for the us market, a lot of them run 11cs which his what euro cars came with. So either use these or there is a cheaper copper plug you can use that many are having joy with, bk something I believe. You will find them using the search function.
