First I want to say hello to everyone and say this great message board. Hello. Here are my questions. I will be completing part of the 120k service myself and wanted to know which parts work best with the Subaru. The Subaru I will be working on is a 95 Legacy L with a 2.2l engine. Stuff I will completing: Spark Plugs Sprak wires 02 sensor PCV Air filter (probaly K&N) I read that NGK or Denso are the best spark plugs for the car, but have not located the part for the NGK or Denso OEM or platinum replacements. Which spark plug is the better choice or are both fairly equal. A part number for the proper NGK or Denso plugs would be appreciated. While on the topic of spark which brand of spark plug wire would provide an upgrade and work well with the car? What is the torque spec for the plugs? Do I need to use anti-seize? Which O2 sensor is better the Bosch or Denso for the Legacy? I have been told Bosch and a few other brands do not well with Subaru’s. I am having the timing belt change by the repair shop; are there any associated parts (gaskets, seals, water pump, belts etc) which need to be replaced? Are there any associated repairs which are required when changing the timing belt? What is the average price for a timing belt replacement? The shop will be changes the fluids as well. Any other recommended repairs or check not listed on the Subaru 120K service interval which should be completed at this time? Thank You
