Virgin WIX 51394 C&P - Some oddities

[MurkyAsparagus]

On the cutter this evening is a WIX 51394. This crosses to a Toyota 90915-YZZN1.

At first glance, the filter looks great. The louvers are nice and open, the pleats are nicely space other than the metal seam, and their isn't a ton of excess glue. However, I thought something was off, so I look a little closer. The metal end caps are not on square. There is a ~1/8 inch difference across the metal end caps. Looking even further, the bypass valve is not centered with the rest of the filter.

Now, I don't know how much these factors will affect performance or function. I do know that PGI would never make these types of mistakes at the moment.

Here are the pictures:

As long as the ADBV seals well between the base plate and end cap then it will function OK. The bypass valve, even though not perfectly centered is still sealing due to the design (see below). There could be quite a bit of radial shift and the sealing lip will still seal the part that moves open and closed. It's not the best looking constructed filter (looks dirty), and has the black sloppy glue that Mann-Hummel likes to use on Purolators.

Not great but I'd say it's more crucial for the end caps to be square on a cartridge than a spin on. Still that build should be done better. Thanks for chopping it up.

Thanks for the info. I hadn't really thought through the construction much, I probably should have.
