I installed a DRP adapter with a Donaldson P553203 on my 15 a few weeks ago and haven't had any issues. It is a super easy install. Can't really tell if its worth it or not but better filtration is better filtration.Also has anyone done the cat filter adaptor on a 15 yet? Worth the 100 bucks?
I've done it on my 11 and "No" it isn't worth it.. In a single filter system you can't beat the OEM ACDelco/Racor or a Baldwin BF9882. In fact the OEM ACDelco/Racor or Baldwin BF9882 also work great in a 2 or 3 filter system as well.Also has anyone done the cat filter adaptor on a 15 yet? Worth the 100 bucks?
