Purflux ls324 oil filter.
Regarding plugs i just swapped pfr6q to ngk twin electrode version...not sure of code, but will say it means i cant fu@€ about gapping 'em AND tickover and moving off is much smoother. Thing is the pfr6q's were only 1k old and looked great when removed but the engine would frequently stutter on manouvering/reversing. With the twin electrodes it's like manouvering a deisel (no throttle required)

that LS324 is the smaller filter, get the larger one. Any decent factors will be able to cross referernce the Mahle OC470 number i gave you, or just put it into ebay.
PFR6Q's come pre gapped and dont need touched. I dont really see the point changing them. That said, i often use BKR6E as they're the same plug but copper rather than platinum, and are about 4x cheaper, but dont last as long.
