Nic Posted October 23, 2011 Share Posted October 23, 2011 The heat range isn't ideal for a BPU Supra and could lead to fouling of the plugs. Have a read of the Spark Plug FAQ guide HERE. Link to comment Share on other sites More sharing options...
sams Posted October 23, 2011 Author Share Posted October 23, 2011 i just read that guide thanks for the link... but im letting my boost peak at 1.4-1.5bar so according to that guide what i got in the min is not good enough but will the ik27 still be wrong heat range or would it be best to try ik24's or BKR8EIX Link to comment Share on other sites More sharing options...
