Steviekid Posted October 14, 2007 Share Posted October 14, 2007 My car ran "ok" at 1.2bar with the same plugs as it had when it was stock until I changed them so I would imagine you'd be ok. From the FAQ however: Stock TT NGK - BCPR6EP-11 - gap to 1.1mm PLATINUM NGK - BKR6E (2756) - gap 1.1mm NGK Iridium - BKR6EIX-11 (3764) leave gap alone Denso Platinum - PK20R11 - gap 1.1mm Denso Iridium - IK20 - leave gap alone TT @ upto 1bar NGK - BCPR7ES (3330) - gap 0.9mm NGK - BKR7E (6097) - gap 0.9mm NGK - Iridium - BKR6EIX or BKR7EIX - leave gap alone Denso Platinum - PK20R11 - gap 0.8mm Denso Iridium - IK22 - leave gap alone Link to comment Share on other sites More sharing options...
Steve Posted October 14, 2007 Share Posted October 14, 2007 I would change to some cooler plugs. The NGK BKR7E (6097) gapped to 0.9 - 0.8mm will be fine. They are only about £12 for 6 plugs. Link to comment Share on other sites More sharing options...
