FJ20 Turbo Spark Plugs

[FJ510]

I know i have asked this question before but what spark plugs are best to run in an FJ20 Turbo.   the car is running 20psi boost and gets driven hard all the time, would it be wise to run a colder plug?   ryan   --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
