ok, my cars oil pressure was very low and i chainged my oil filter only oil filter and pressure is great when I push the gas oil pressure gos more then 75% up, if ou have problems with oil pressure you shude change oil and oil filter and thei is uther filter 1 inch biger from mazda 626 engines
The part number for these are Carquest # 85356 or Fram # PH7317. This filter has the exact same specifications as ours except that it is 1" longer.This means more cleaning power for our hi-revving engines. My engine still held only 4 qts of oil after installing the new filter. Hope this helpful
