What oil filter do you use? Do you have a bypass? If you use more than one kind, list your preffered filter. Trying to see what's the most common. If you use a Stratpore LF3894 just select the LF16035. If you use a Hastings LF608 just select Baldwin BT7349. Here is the data I have on the filters listed.
