The Boss and Titaniums are both overkill filters for OPE, and still way cheaper than the OPE branded filters. I've always said the OPE filters are fine, nothing wrong with them, they just aren't a good value. I was in Tractor Supply this weekend and happened to go down the OPE aisle. There wasn't an oil filter under $12, and the $12 one was a cheap knock-off.at work i run a Purolator BOSS 3614 sized filter. it will be getting an OG wire backed Titanium FS3600 on friday.
