I think auto shop spares is definately the way to go. However you do need to be careful to get filters etc of equal specification or better than the genuine part. Most of the very cheap
alternatives are sub standard. Most of the big auto workshops will have filter catalogues that will cross reference the manufacturers part number to their own non genuine part numbers. I used to own an independant franchised auto workshop and the auto manufacturers hated us. If you fit genuine filters and seize your engine
, the engine
manufacturer will never blame their own filter and you pay for repairs
. If you fit a non genuine filter and seize the engine the engine manufacturer (or their dealer) will often try to blame the non-genuine part. If they do, try to get it in writing because the suppliers of quality non genuine parts often have very zealous legal
departments who love to defend their product against the unwarranted slurs from the genuine manufacturers and it means you can win big time. Anyway, put in good quality parts, genuine or otherwise and you won't be seizing engines.
