Weyro Posted April 18, 2013 Share Posted April 18, 2013 Ive been running a td04 at 1 bar for nearly a year now. I recently changed the plugs to Heat range 8's, the ones that came out were only range 5. Is 8 too cold? What problems would running a too cold plug cause? Reduced power?

AdamB Posted April 18, 2013 Share Posted April 18, 2013 8's is way too cold mate for that setup. 7's will do nicely till probably about 400bhp. Quote Link to post Share on other sites
Foggy Posted April 18, 2013 Share Posted April 18, 2013 As above. Heat range 8 could give a cold start issue. Im running 7s on a td05 with no issues. Quote Link to post Share on other sites
Weyro Posted April 18, 2013 Author Share Posted April 18, 2013 ok cool, car seems to be running spot on, so would i be safe waiting till i service it next? Quote Link to post Share on other sites
