168517-0 supersedes older part numbers: 965603021
Original Makita spark plug 168517-0 (BPMR7A) — a direct replacement spark plug for Makita 2‑stroke petrol tools. It’s the NGK‑style BPMR7A design with an M14 thread, approximately 9.5 mm thread engagement and a 19 mm hex for tightening; overall length is about 52 mm.
This genuine Makita plug is listed for several Makita handheld petrol units — for example DBC3300 / DBC4000 / DCS520 / DPC7301 / DCS461 and PS7310 so it’s a good match if your tool’s parts diagram shows 168517-0.
Factory guidance for the same engines calls for a spark‑gap of about 0.6–0.7 mm, so set the gap before installation for reliable starting and clean combustion.
If you need a straightforward, original Makita replacement to get a two‑stroke Makita petrol tool back in service, this spark plug is a simple, exact‑fit repair part — one of the Makita parts you’ll want on hand for routine maintenance and repairs.
