Damn sure is. 01082-R. Same p/n. I run P5 plugs in it. P4 if it's cold out. I'm not against RB plugs, they are scarce here. I can get OS plugs at taco bell's drive-thru, lol. P6's won't even keep my JP running cuz it's they're so cold and i'm only running .6mm shims in a motor that had .7mm in it. A 97t is hotter than a P3.
