    NGK DCPR8E # 4339. You can buy them at any auto parts store that sells NGK plugs. Cheaper than dealers sell them for and the exact plug that dealers get from BRP.

    i have been using the NGK DPR9EA-9. i found the plug to be great. i was going through the original plugs too quick. and these are for modded boats since they run cooler hence the 9 not 8. this is a standard dirtbike plug.

    Do they come pre-gapped or do we need to set the gap? I picked up three NGK DCPR8E # 4339 of these earlier at advance auto for 2.39 a piece.

    My Ski only has 36 hours but Im about to change the oil for the first time (since the factory 10hr service) and install a groco strainer, and replace the stock hose clamps with the ones from silinconeintakes.com so I figured I would do this as well.

    Thanks!
