NGK BPMR7A. NGK's cross-reference catalog lists BPMR7A (stock number 4626) for Champion RCJ7Y, the same NGK plug it lists for RCJ6Y. Set the gap to your saw's specification: our Husqvarna 120 and 435 to 460 records list 0.5 mm, and the Poulan Pro P3314 to PP4620AV records list 0.025 in (about 0.6 mm).

Where RCJ7Y Is Used
Husqvarna's operator manual for the 120 Mark II specifies Champion RCJ7Y at 0.5 mm. Our records for the Husqvarna 435, 440, 445, 450, 455 Rancher, and 460 Rancher list RCJ7Y or BPMR7A at the same gap.
The Poulan Pro P3314, P3816, PP4218A, and PP4620AV records list Champion RCJ-7Y at 0.025 in. RCJ-7Y and RCJ7Y are the same plug written two ways.
Why RCJ6Y and RCJ7Y Share One NGK Number
NGK's catalog maps both Champion plugs to BPMR7A. The two Champion plugs sit one step apart in heat range, and NGK does not list a separate plug for each.
If your manual names one specific Champion plug, that is the safest match. Use BPMR7A when the manual or model page lists it as an option.
