April 1, 201214 yr Trying to find an NGK plug equiveland to the Denso original plug from my 2012 250 ?? The Denso is marked W16EP-U Anyone know ??
April 5, 201214 yr Do yourself a favour and get the irridium type, part code is: Ngk BPR5EIX Better yey, see if you can still locate a BP5EVX platinum, non resistor plug, the doggies dangler!
April 28, 201214 yr Sorry I'm late contributing to this one.. This is acut-n-past from a previous post. One thing a lot of people do not pick up on is there are two types of NGK Iridiums. There is a standard gap EIX and a large gap EIX . The large gap EIX is the most commonly found in Auto Parts shops, but the gap is way too BIG for modern Trials bikes. Check the code _ small gap will be say NGK BKR5 EIX (no numbers after the EIX) or BKR5EIX-11. The large gap will be say NGK BKR5 EIX 14 (two numbers after the EIX) both will work if gapped correctly, but if you chuck in a large gap iridium as it comes in the box you are wasting your $$$$$, and will be up for a new one in no time. BKR5EIX-11 gapped to 0.7mm. All the best. Neo
