I tend to stick with NGK, as far as brands go. Nissan OEM, tried and true. As far as which flavor...the cost-to-mileage ratio used to be fairly linear, but it's gotten diluted as the cheaper plugs have just become overpriced and rival better-performing plugs. In you case, going with those ruthenium ones you linked at $11/ea beats paying $10/ea for the OE-recommended double platinum ones (p/n 6240, a.k.a. PLFR5A-11) because you'll basically have a plug that far exceeds platinum tech in every way, including not having to replace them for another 100K-120K miles (vs. 50K-60K). Ultimately, I'd love for you to keep that engine running up toward 400K! Hose and jet sprayer probably isn't terrible. Otherwise, get a can/bottle of engine degreaser, head to the local spray-n-wash, spray the degreaser on and let it sit a couple minutes, then wash it off. Of course, a lot of spray-n-wash places have built in engine degreaser modes, plus a reduced spray for underhood use...but I like to go full blast.1 point
