Wix "flying saucer" bypass...

[geeeman]

I just purchased 2 Napa Gold 1344 oil filters for my Hondas. Both came in identical boxes, but the filters were completely different, except for the number, 1344. (Oversize for the 1334)

The first one was the regular style 1344 I'm used to; orange ADBV, conventional bypass (closed end) etc. The second one was bigger in diameter, had a black ADBV and had the Wix open end by-pass valve. Whats up with that...and does anyone know if this style bypass is better or worse. It seems like it might give the oil more area to bypass through (a good thing for cold starts?), but it's just so, well...DIFFERENT!!!

I've wondered the same thing myself, as the Wix filter for my vehicle also has this style by-pass valve. The other brands of filters (Motorcraft, Fram, Purolator, etc...) have the more well-known "spring w/ valve" type. I would love to know the advantages/disadvantages of one over the other.

Interesting. Perhaps Wix, when changing to their newer "T03" media and silicone bypass for this particular part #, also decided to change to closed-end bypass as well..? Perhaps they consolidated components for two or more filter part numbers, streamlining inventory. Wix makes great stuff -- personally I wouldn't hesitate to keep and use both filters.

Here's a good article, plus illustrations, on bypass arrangements:

You want to by-pass closest to the engine mount..less travel over dirty media to valve...Ford specs this type of by-pass...so the major manufacturers make em' that way...best system for a spin on filter...bought a load of Wix Sport Truck filters (5151ST)..nice filter for the money
