Gurus, I have a question regarding Baldwin B178 and B199. Same naman sila ng diameter and length but according also to the Baldwin website "Baldwin Filters E-Catalog"
B178 Anti-Drainback Valve
30 PSID By-Pass Valve
B199 Anti-Drainback Valve
8 PSID By-Pass Valve
The one I'm using now on our Vios 1.3 (BT223) is 8 PSID By-Pass Valve
What does the 8 or 30 PSID mean? May masamang effect ba sa engine if I used a lower number (8) than a higher one (30) and vice versa? Planning to use either B178 or B199 on the next oil change of my dad's Civic EK (PH15A engine). I checked the location of the oil filter (real quite hard to see, but I think it has a lot of space to cater to a longer oil filter). Thanks.
Here's the photo
