i remember nung pumunta ako sa wix distributor sa q.ave, it seems they don't really give much thought on bringing stocks of filters for the retail-automotive sector, the cars, suv's... same with volmax,

meron sila libro ng catalogue at cross reference, pero bawat tanung ko panay walang stocks...puro pang heavy duty and pang large machines....

sa distributor ng parker racor at donaldson filters, ganun din wala sila stocks ng mga sizes that belongs to the car segment...
