The denso iridium spark plug for sachs 49er 50 2006-2008 is part of the latest collection from denso.Features: six times harder than platinum, iridium withstands temperatures up to 4,000â f because the iridium electrodes of these plugs can be shrunk to only 0.4Mm, voltage requirements decrease while firing performance improves 360â laser welding of electrode provides a seal that resists wear even in the worst conditions ground electrode features a tapered cut and u-groove that form a large volume area for the flame's center specifications: center electrode projection: non-projected center electrode type: fine wire electrical resistance: 5k ohms electrode tip material: iridium ground electrode shape: grooved taper cut heat range: 22 hex size imperial: 5 8 hex size metric: 16 mm hex size: 16 mm 5 8 model: iuf22 product name: spark plug research value: finalized to fit: beta cross r 125 2009 all models beta cross r 125 2010 all models beta minimoto 2009 all models beta minimoto 2010 all models beta rr 125 2006 all models beta rr 125 2007 motard european models beta rr 125 2007 all models beta rr 125 2008 motard european models beta rr 125 2008 all models beta rr 125 2009 motard european models beta rr 125 2009 all models beta rr 125 2010 motard european models beta rr 125 2010 all models beta rr 125 2011 motard european models beta rr 125 2011 all models beta rr 125 2012 motard european models beta rr 125 2012 all models beta rr 125 2013 motard european models beta rr 125 20...
