This is the replacement spark plug to for my Toro QZR 621 snowblower. You can use either ngk bpr6es brand or this Champion brand RN 9YC. The correct gap to be set for my snowblower is 0.030 inches or 0.76mm as stated in operator manual. You will have to adjust the gap for your snow blower when buying this brand new from the store.
